[0005] To achieve the above objectives, this application provides a workpiece machining method applied to a machine tool. The machine tool is equipped with a composite cutting tool, which includes a tool holder and a cutting head connected in sequence. The cutting head includes a chamfering tool, a finishing tool, and a roughing tool connected in sequence. The chamfering tool is located at one end near the tool holder, and the roughing tool is located at one end away from the tool holder.

The composite tool is controlled to feed from the center position of the preset hole, so that the roughing tool roughens the workpiece, the finishing tool finishes the roughened hole wall, and the chamfering tool chamfers the hole opening to machine a positioning hole on the workpiece.

[0006] In one embodiment, the roughing cutter includes a drill bit and a taper, the drill bit being disposed at one end near the finishing cutter, and the taper being disposed at the other end away from the finishing cutter.

When the machining type is blind hole, if the target machinable depth is equal to the target finishing depth, the difference between the target machinable depth and the target finishing depth is less than the first tool length, or the target finishing depth is greater than the second tool length, then a tool replacement prompt is output.

[0009] In one embodiment, after the step of obtaining the machining type of the preset positioning hole on the workpiece to be machined, the workpiece machining method further includes: When the machining type is through hole, if the target finishing depth is greater than the second tool length and the target finishing depth is less than or equal to twice the second tool length, then when the diameter of the roughing tool of the composite tool is less than the target hole diameter of the positioning hole and the diameter of the finishing tool is equal to the target hole diameter, the workpiece to be machined is machined on both sides by the composite tool.

[0010] In one embodiment, the preset hole center position includes a first center and a second center, and the step of performing double-sided machining on the workpiece using the composite tool includes: For positioning holes with a through-hole machining type, a first center and a second center are determined from the preset hole center position, and the first center and the second center are coaxial and opposite to each other; The composite tool is positioned at the first center and fed axially from the first center to obtain the single-sided feed depth, and the composite tool is positioned at the second center and fed axially from the second center to obtain the single-sided feed depth, so as to process and form a through hole.

[0011] In one embodiment, the step of obtaining the single-sided feed depth includes: Obtain the chamfering depth of the chamfering tool of the composite tool, and take the sum of the first cutting length of the roughing tool, the second cutting length of the finishing tool, and the chamfering depth as the single-sided feed depth.

[0012] Furthermore, to achieve the above objectives, this application provides a workpiece processing apparatus applied to a machine tool. The machine tool is equipped with at least one composite tool, which includes a tool holder and a tool head connected in sequence. The tool head includes a chamfering tool, a finishing tool, and a roughing tool connected in sequence. The chamfering tool is located at one end near the tool holder, and the roughing tool is located at one end away from the tool holder. The workpiece processing apparatus includes: The positioning module is used to position the composite tool at the center position of the preset positioning hole on the workpiece to be processed; The control module is used to control the composite tool to feed from the center position of the preset hole, so that the roughing tool roughens the workpiece to be processed, the finishing tool finishes the hole wall after roughing, and the chamfering tool chamfers the hole opening to process a positioning hole on the workpiece to be processed.

[0013] In addition, to achieve the above objectives, this application also provides a machine tool device, which includes: a memory, a processor, and a program for the workpiece machining method stored in the memory and executable on the processor.

Thus, the three processes of roughing, finishing and chamfering are completed sequentially in one composite tool, one positioning and one continuous feed process, avoiding the multiple shutdowns, tool changes and repositioning operations caused by the need to use three different tools to process separately in the prior art, reducing processing time and thus effectively improving workpiece processing efficiency.

[0021] The objectives, features, and advantages of the embodiments described in this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of the embodiments of this application and are not intended to limit the embodiments of this application.

[0023] To better understand the technical solutions of the embodiments of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0024] In product manufacturing, especially for watch cases, locating holes are a crucial machining step. To better distinguish the clamping direction of the product and prevent parts from being installed backwards or incorrectly, two locating holes of different sizes are usually designed, such as φ3 and φ4. These locating holes serve as product references to ensure the accuracy of the relative position of the product's structure in subsequent processing and to guarantee consistency in repeated assembly. Positioning the product using locating holes restricts the part's degrees of freedom (such as rotation or translation). In actual machining, three different cutting tools are usually required, and each tool change necessitates tool switching and repositioning, which increases machining time and leads to low workpiece machining efficiency.

[0025] Therefore, this embodiment provides a workpiece machining method. The machine tool in this embodiment is equipped with a composite tool, wherein the cutting head of the composite tool includes a chamfering tool, a finishing tool, and a roughing tool connected in sequence. The chamfering tool is located at the end near the tool holder, while the roughing tool is located at the end away from the tool holder. In this embodiment, after positioning the composite tool at the center position of the preset positioning hole on the workpiece to be machined, the composite tool is controlled to feed from the center position of the preset hole in one pass. The roughing tool performs roughing machining on the positioning hole, the finishing tool performs finishing machining on the roughened hole wall, and the chamfering tool performs chamfering machining on the hole opening. Thus, the three processes of roughing, finishing, and chamfering are completed sequentially in one composite tool, one positioning, and one continuous feed. This avoids the multiple downtimes, tool changes, and repositioning operations caused by the need to use three different tools for machining in the prior art, which reduces machining time and effectively improves workpiece machining efficiency.

[0026] Based on this, the embodiments of this application provide a workpiece processing method, referring to... Figure 1 and Figure 2 , Figure 1 This is a flowchart illustrating the first embodiment of the workpiece processing method of this application. Figure 2 This is a schematic diagram of a composite cutting tool. The workpiece machining method is applied to a machine tool equipped with at least one composite cutting tool. The composite cutting tool includes a tool holder and a cutting head connected in sequence. The cutting head includes a chamfering tool, a finishing tool, and a roughing tool connected in sequence. The chamfering tool is located at the end closest to the tool holder, and the roughing tool is located at the end furthest from the tool holder. The method includes steps S10 to S20: Step S10: Position the composite tool at the center position of a preset hole on the workpiece to be processed, wherein the center position of the preset hole is the center position of the positioning hole that is determined in advance on the surface of the workpiece to be processed. It should be noted that the machine tool is equipped with a composite tool. The machine tool can hold the composite tool by using a tool holder. For example, when machining is required using a composite tool, the composite tool can be clamped in the machine tool, and the machining can be controlled by the clamped composite tool. When machining is not required using a composite tool, the composite tool can be installed in the tool holder of the machine tool. The tool holder is used to store the tool, and the machine tool can have multiple tool holders.

[0027] A composite cutting tool is a combination tool that connects a roughing tool, a finishing tool, and a chamfering tool sequentially along the axial direction on the same tool holder, enabling roughing, finishing, and chamfering to be completed in a single operation. The tool holder is the clamping part of the composite cutting tool used to connect to the machine tool spindle, and its end is connected to the tool head. The tool head is the working part of the composite cutting tool used to directly cut the workpiece, and it is composed of a chamfering tool, a finishing tool, and a roughing tool connected sequentially. For example, refer to... Figure 2 , Figure 2 A structural diagram of a composite cutting tool is shown, including the tool holder DB and the cutting head DT.

[0028] The roughing cutter is the cutting tool section located at the end of the cutter head furthest from the tool shank. It is used for initial, large-scale cutting of the positioning hole, removing most of the material. The finishing cutter is the cutting tool section located between the roughing and chamfering cutters. It is used for finishing the roughened hole wall; the finishing cutter can be a reamer. The chamfering cutter is the cutting tool section located at the end of the cutter head closest to the tool shank. It is used to machine the edges of the finished hole to create a chamfer.

[0029] The workpiece to be processed is the workpiece that requires the machining of positioning holes. The positioning holes are pre-set holes on the workpiece to be processed, which can be used for subsequent assembly or as machining references. The center position of the pre-set hole is the center position of the positioning hole on the surface of the workpiece to be processed; the center position of the pre-set hole can be predetermined on the workpiece to be processed, but this embodiment does not impose a specific limitation on this, and it can be set according to the actual situation.

[0030] In this embodiment, the composite tool for positioning the center position of the preset hole supports machining the preset positioning hole on the workpiece to be machined. Before positioning the composite tool to the center position of the preset hole on the workpiece to be machined, a composite tool that can be used to machine the positioning hole on the workpiece to be machined can be determined in the machine tool equipment so that the workpiece to be machined can be machined accurately.

[0031] For example, the machine tool can be controlled to clamp a composite tool (a composite tool that supports machining positioning holes on the workpiece); the workpiece is fixed on the worktable of the machine tool, and the workpiece has a preset hole center for machining the positioning hole. The composite tool is controlled to move and position itself to the preset hole center on the workpiece. After positioning, it is ensured that the composite tool and the preset hole center are coaxial to avoid positioning offset during subsequent machining. The hole parameters may include at least the target hole diameter, target finishing depth, and target machinable depth of the positioning hole, etc., but this embodiment does not specifically limit these parameters.

[0032] In one feasible embodiment, the roughing tool includes a drill bit and a cone angle. The drill bit is located at one end close to the finishing tool, and the cone angle is located at one end away from the finishing tool. Step S10 also includes step S11: controlling the cone angle to be positioned at the center of a preset hole so that the composite tool is positioned at the center of the preset hole.

[0033] It should be noted that the cone angle refers to the part of the roughing tool that is far from the finishing tool. Together with the drill bit, it forms the roughing tool. During the positioning stage of the composite tool, the cone angle first contacts the center position of the preset hole on the workpiece. The cone angle achieves positioning guidance through its conical structure, ensuring that the composite tool can accurately align with the center of the preset hole surface and avoid positioning deviation. At the same time, in the early stage of roughing, it can assist the drill bit in centering, reduce the shaking of the drill bit during cutting, and improve the stability and accuracy of roughing.

[0034] The drill bit refers to the component near the finishing cutter end of the roughing tool. Together with the taper, it forms the roughing tool. After the taper provides positioning and guidance, the drill bit cuts the workpiece material at the center of the pre-set hole position surface, quickly removing excess material and initially forming the shape of the positioning hole. The taper, roughing tool, finishing cutter, and chamfering tool are coaxially arranged.

[0035] For example, the cone angle is controlled to be positioned at the center of the preset hole surface. The cone shape of the cone angle is used to achieve precise centering and guidance, so that the entire composite tool is precisely positioned at the center of the preset hole. The center of the preset hole can be a point. The angle of the cone angle can be 140°.

[0036] This embodiment uses cone angle positioning to achieve rapid and accurate positioning of the composite tool, effectively avoiding the problem of composite tool positioning offset and improving the positional accuracy of positioning hole machining.

[0037] For example, you can refer to Figure 3 , Figure 3 An enlarged schematic diagram of the composite tool is given, from... Figure 3 As can be seen from this, the cutting head includes a chamfering tool D1, a finishing tool D2, a drill bit D3, and a taper angle D4. Figure 3It can also be seen that the cone angle is 140°, the taper of the chamfering tool can be 90°, and the bevel of the chamfering tool can be 45°.

[0038] Step S20: Control the composite tool to enter from the center position of the preset hole, so that the roughing tool performs roughing of the workpiece to be processed, the finishing tool performs finishing of the roughened hole wall, and the chamfering tool performs chamfering of the hole opening, so as to process the positioning hole on the workpiece to be processed.

[0039] It should be noted that the composite tool can be controlled to feed axially from the center position of the preset hole. The roughing tool is used for roughing, the finishing tool is used for finishing, and the chamfering tool is used for chamfering.

[0040] After the control compound tool enters from the center of the positioning hole, roughing is performed using a roughing tool to initially machine the approximate shape and size of the positioning hole. Finishing refers to the fine machining of the hole wall after roughing using a finishing tool. This corrects dimensional errors, surface unevenness, burrs, and other defects generated during roughing, ensuring that the dimensional accuracy and surface roughness of the positioning hole meet the preset standards. The hole opening refers to the open end of the positioning hole, that is, the edge where the positioning hole connects to the surface of the workpiece. A chamfering tool removes sharp edges and burrs from the hole opening, making the edge smooth.

[0041] For example, the machine tool controls a composite cutting tool to feed axially into the workpiece from the center of a preset hole. During the feed, since the roughing tool is located at the end furthest from the tool holder, it contacts the workpiece first and roughens the workpiece material at the center of the preset hole surface, quickly removing excess material and initially forming the shape of the positioning hole. As the composite cutting tool continues to feed, the finishing tool located between the roughing tool and the chamfering tool gradually contacts the roughened hole wall and performs finishing on the roughened hole wall. As the tool continues to feed, the chamfering tool located near the tool holder contacts the opening of the positioning hole and performs chamfering on the opening, removing sharp edges and burrs, making the opening smooth, and thus completing the machining of the positioning hole on the workpiece.

[0042] The machine tool in this embodiment is equipped with a composite tool, wherein the tool head includes a chamfering tool, a finishing tool, and a roughing tool connected in sequence. The chamfering tool is located at the end near the tool holder, while the roughing tool is located at the end away from the tool holder. In this embodiment, after positioning the composite tool at the center position of the preset positioning hole on the workpiece to be processed, the composite tool is controlled to feed in one pass from the center position of the preset hole. The roughing tool performs roughing of the positioning hole, the finishing tool performs finishing of the roughened hole wall, and the chamfering tool performs chamfering of the hole opening. Thus, the three processes of roughing, finishing, and chamfering are completed sequentially in one composite tool, one positioning, and one continuous feed. This avoids the multiple downtimes, tool changes, and repositioning operations caused by the use of three different tools for processing in the prior art, which reduces processing time and effectively improves workpiece processing efficiency.

[0043] In a feasible embodiment, the workpiece processing method further includes steps A10 to A20: Step A10: Obtain the target hole diameter of the positioning hole to be machined in the workpiece; It should be noted that the target aperture is the aperture size that the positioning hole on the workpiece to be processed needs to achieve in the final machining process.

[0044] Step A20: If the diameter of the roughing tool of the composite tool is greater than or equal to the target hole diameter, and / or the diameter of the finishing tool is not equal to the target hole diameter, then output a prompt to change the tool.

[0045] It should be noted that the diameter of the roughing cutter refers to the maximum outer diameter of the drill bit portion within the roughing cutter. The diameter of the roughing cutter should be smaller than the target hole diameter to allow sufficient cutting allowance for the finishing cutter. The diameter of the finishing cutter refers to its outer diameter, which should be precisely equal to the target hole diameter to ensure that the size of the locating hole after finishing meets the design requirements. In other words, the diameter of the locating hole after finishing is the target hole diameter.

[0046] The tool replacement prompt refers to the notification to the operator to replace the composite tool when the machine tool detects that the currently clamped composite tool does not meet the machining conditions (the diameter of the roughing tool is greater than or equal to the target hole diameter, and / or the diameter of the finishing tool is not equal to the target hole diameter). This is done by displaying text and / or issuing an audible and visual alarm on the machine tool's screen.

[0047] In other embodiments, when the machine tool detects that the diameter of the roughing cutter of the currently clamped composite tool is greater than or equal to the target hole diameter, and / or the diameter of the finishing cutter is not equal to the target hole diameter, a target tool with a roughing cutter diameter smaller than the target hole diameter and a finishing cutter diameter equal to the target hole diameter can be selected from the preset composite tools of the machine tool, and the target tool can be used as a composite tool for machining the positioning hole of the workpiece to be machined.

[0048] Specifically, before positioning the composite tool at the center position of the preset hole on the workpiece, it can be detected whether the diameter of the roughing tool in the composite tool currently held by the machine tool is less than the target hole diameter and whether the diameter of the finishing tool is equal to the target hole diameter. If the diameter of the roughing tool is greater than or equal to the target hole diameter and / or the diameter of the finishing tool is not equal to the target hole diameter, a tool replacement prompt is output, and the composite tool used to process the positioning hole is determined from the preset composite tools of each machine tool according to the hole parameters of the positioning hole.

[0049] For example, the target hole diameter of the positioning hole to be machined on the workpiece is obtained; the machine tool automatically reads the diameter of the roughing tool and the diameter of the finishing tool in the currently clamped compound tool. If the diameter of the roughing tool is detected to be greater than or equal to the target hole diameter, or the diameter of the finishing tool is detected to be not equal to the target hole diameter, or if the diameter of the roughing tool is greater than or equal to the target hole diameter and does not match the diameter of the finishing tool, a tool replacement prompt is output. The tool replacement prompt may also include replacing the compound tool with a diameter that is more compatible with the tool.

[0050] This embodiment allows for advance compatibility testing of the roughing and finishing tools of the composite cutting tool with the target hole diameter. This effectively avoids problems such as the hole diameter being larger than or equal to the target hole diameter after roughing due to the roughing tool diameter being too large or equal to the target hole diameter, which would prevent subsequent finishing from correcting the issue, or the final forming size of the positioning hole being unqualified due to the mismatch between the finishing tool diameter and the target hole diameter. This reduces the generation of processing waste and improves the dimensional accuracy of positioning hole processing and the workpiece processing pass rate. At the same time, by promptly outputting tool replacement prompts, it can prevent operators from continuing processing when the tools are incompatible, reducing ineffective processing time and material waste.

[0051] In a feasible embodiment, the workpiece processing method further includes steps B10 to B20: Step B10: Obtain the machining type of the preset positioning hole on the workpiece to be machined, the target finishing depth and the target machinable depth of the positioning hole, and obtain the first cutting length of the roughing tool and the second cutting length of the finishing tool in the composite tool. It should be noted that the machining type refers to the structural form of the pre-set hole to be machined on the workpiece. Machining types can be divided into two types: blind holes and through holes. A blind hole is a hole that does not penetrate the workpiece, and its bottom is located inside the workpiece; a through hole is a hole that penetrates the workpiece, and both ends of the through hole are connected to the outside.

[0052] The target finishing depth refers to the axial depth to which the positioning hole to be machined needs to be finished. The target machinable depth is the maximum depth that a composite tool can machine at the preset hole center position on the workpiece. The target machinable depth can be determined based on actual conditions. For example, the target machinable depth can be determined based on factors such as the structure and size of the workpiece itself, and also based on the design requirements of the workpiece. This embodiment does not impose specific limitations on this. For example, in some scenarios, the target machinable depth can be set to be equal to the target finishing depth according to the workpiece design requirements. In other possible scenarios, the target machinable depth can also be greater than the target finishing depth. This embodiment does not impose specific limitations on this and can be flexibly adjusted according to actual machining needs.

[0053] The first cut length is the axial length of the roughing cutter in a compound tool set, which is the sum of the axial length of the drill bit and the axial length of the taper angle in the roughing cutter. The second cut length is the axial length of the finishing cutter in a compound tool set.

[0054] Step B20: When the machining type is blind hole, if the target machinable depth is equal to the target finishing depth, the difference between the target machinable depth and the target finishing depth is less than the first tool length, or the target finishing depth is greater than the second tool length, then output a tool change prompt.

[0055] It should be noted that since one end of a blind hole is closed, the machining depth of a blind hole is limited. Therefore, when the positioning hole to be machined is a blind hole, the tool feed depth during the machining process cannot exceed the target machinable depth, otherwise the workpiece to be machined may be damaged.

[0056] In blind hole machining, if the target machinable depth equals the target finishing depth, it means there is no redundant space at the bottom of the hole for the roughing tool. When the compound tool reaches the target finishing depth, the finishing tool has completed the finishing of the hole wall. However, because it is a blind hole, the roughing tool located below the finishing tool cannot withdraw from the workpiece and is instead pressed further into the hole. Since the roughing tool has a certain length, if it continues to advance to complete the finishing and chamfering, the tip of the roughing tool will be forced into the bottom of the hole, causing the actual depth of the locating hole to exceed the target machinable depth, rendering the workpiece unusable or failing to meet design requirements.

[0057] The difference between the target machinable depth and the target finishing depth is the redundancy depth, which is the depth of the hole segment that can be rough-machined but does not require finishing. If the difference between the target machinable depth and the target finishing depth is less than the first cut length, it will also lead to an excessive roughing feed, making the final depth of the positioning hole too deep, exceeding the target machinable depth. If the target finishing depth is greater than the second cut length, the finishing cutter cannot completely finish the hole wall, and because the chamfering cutter diameter is larger than the finishing cutter, the larger diameter chamfering cutter will enter the already finished small-diameter hole segment, causing a collision, which will result in the positioning hole in the workpiece not meeting the requirements.

[0058] For example, the machining type, target finishing depth, and target machinable depth of the preset positioning hole on the workpiece to be machined are obtained, and the first cutting length of the roughing tool and the second cutting length of the finishing tool in the currently clamped compound tool are obtained. If the preset positioning hole machining type of the workpiece to be machined is a blind hole, if the target finishing depth is greater than the second cutting length or the difference between the target machinable depth and the target finishing depth is less than the first cutting length, the machine tool will output a tool replacement prompt. If the target finishing depth of the blind hole is equal to the target machinable depth, a tool replacement prompt will also be output. When the target finishing depth of the blind hole is equal to the target machinable depth, it means that the compound tool does not support machining the positioning hole to be machined in the workpiece to be machined. Such positioning holes need to be machined sequentially with separate tools and cannot be machined with the compound tool.

[0059] If the target finishing depth is greater than the second cut length, or the difference between the target machinable depth and the target finishing depth is less than the first cut length and greater than zero, it indicates that the tool needs to be replaced. The replaced tool can also be a composite tool, that is, a composite tool for machining the positioning hole in the workpiece can be selected from the preset composite tools of the machine tool equipment.

[0060] Specifically, before positioning the composite tool at the center position of the preset hole on the workpiece, it can first detect whether the diameter of the roughing tool in the composite tool currently held by the machine tool is less than the target hole diameter, whether the diameter of the finishing tool is equal to the target hole diameter, whether the difference between the target machinable depth and the target finishing depth is less than the first tool length, and whether the target finishing depth is the second tool length. If it is detected that the diameter of the roughing tool of the composite tool is greater than or equal to the target hole diameter, the diameter of the finishing tool is not equal to the target hole diameter, the target finishing depth is greater than the second tool length when the machining type is blind hole, and / or the difference between the target machinable depth and the target finishing depth is greater than zero and less than the first tool length, a tool replacement prompt is output until it is detected that the diameter of the roughing tool of the composite tool is less than the target hole diameter, the diameter of the finishing tool is equal to the target hole diameter, the target finishing depth is less than or equal to the second tool length when the machining type is blind hole, and the difference between the target machinable depth and the target finishing depth is greater than or equal to the first tool length.

[0061] If it is detected that the diameter of the roughing cutter of the composite tool is smaller than the target hole diameter, the diameter of the finishing cutter is equal to the target hole diameter, and the target finishing depth is less than or equal to the second cutter length when the machining type is blind hole, and the difference between the target machinable depth and the target finishing depth is greater than or equal to the first cutter length, it is determined that the composite tool currently held by the machine tool supports machining the positioning hole to be machined in the workpiece to be machined, and thus supports the execution of the step: positioning the composite tool to the center position of the preset hole on the workpiece to be machined.

[0062] This embodiment comprehensively identifies risks such as excessively large hole diameter, excessively deep hole depth, and chamfering tool collision interference that may result from mismatched tool sizes. It can promptly prompt tool replacement until a perfectly compatible tool is selected, thereby effectively avoiding workpiece scrap and tool damage, and ensuring the dimensional accuracy of blind hole machining.

[0063] In a feasible embodiment, step B30 is further included after step B10: when the machining type is through hole, if the target finishing depth is greater than the second tool length and the target finishing depth is less than or equal to twice the second tool length, then when the diameter of the roughing tool of the composite tool is less than the target hole diameter of the positioning hole and the diameter of the finishing tool is equal to the target hole diameter, the workpiece to be machined is machined on both sides by the composite tool.

[0064] It should be noted that double-sided machining refers to machining two opposite surfaces of the workpiece to obtain a positioning hole for a through hole type.

[0065] Furthermore, double-sided machining can compensate for the insufficient second cutting length of the finishing tool. When the target finishing depth of the through hole is greater than the second cutting length of the finishing tool, and the target finishing depth is less than or equal to twice the second cutting length, the finishing tool cannot complete the finishing machining of the entire through hole wall by entering the tool from one side. However, since the through hole has the characteristic that both ends are connected to the outside, the finishing tool can complete the finishing machining of part of the hole wall on both sides by entering the tool from both sides, thus eliminating the need to change the composite tool, which ensures machining accuracy and improves machining efficiency.

[0066] For example, when the machining type is through hole, if the target finishing depth is less than or equal to the second tool length, then the workpiece to be machined is machined on one side when the diameter of the roughing tool of the composite tool is less than the target hole diameter of the positioning hole and the diameter of the finishing tool is equal to the target hole diameter; if the target finishing depth is greater than twice the second tool length, then a tool replacement prompt is output to replace it with a composite tool with a roughing tool diameter less than the target hole diameter of the positioning hole, a finishing tool diameter equal to the target hole diameter, and a second tool length less than or equal to the target finishing depth.

[0067] Because the finishing depth on one side of a compound tool cannot exceed the length of the second cutter, otherwise the chamfering cutter above it will enter the already finished small-diameter hole section before the finishing cutter has completed its finishing, causing a collision. Therefore, when performing double-sided machining, the longest finishing length is twice the length of the second cutter. Thus, when the target finishing depth is greater than the length of the second cutter, and the target finishing depth is less than or equal to twice the length of the second cutter, and the diameter of the roughing cutter of the compound tool is less than the target hole diameter of the positioning hole, and the diameter of the finishing cutter is equal to the target hole diameter, the workpiece can be machined on both sides using a compound tool.

[0068] In a feasible embodiment, the preset hole center position includes a first center and a second center, and step B30 further includes steps B31 to B32: Step B31: For positioning holes with a machining type of through hole, determine the first center and the second center from the preset hole center position. The first center and the second center are coaxial and opposite to each other. It should be noted that when double-sided machining of the positioning hole in the workpiece is required, the preset hole center position includes a first center and a second center. The first center is a single point, and the second center is also a single point. The first center and the second center are coaxial and opposite to each other. When single-sided machining is required instead of double-sided machining of the positioning hole, the preset hole center position does not include the first center and the second center; the preset hole center position is simply a single point.

[0069] The first center is located on one surface of the workpiece, corresponding to the center of one side of the through hole opening. It serves as the positioning reference point for the compound tool when entering the machine from that side. It is coaxial with the second center to ensure precise alignment of the hole sections machined from both sides. The second center is located on the other surface of the workpiece opposite to the first center, corresponding to the center of the other side of the through hole opening, and is coaxial with the first center.

[0070] Step B32: Obtain the single-sided feed depth, control the composite tool to be positioned at the first center and feed the single-sided feed depth axially from the first center, and control the composite tool to be positioned at the second center and feed the single-sided feed depth axially from the second center to process and form a through hole.

[0071] It should be noted that the single-sided feed depth refers to the depth of a single axial feed of the composite tool from the first center or the second center. This embodiment can control the composite tool to feed from both the first and second centers respectively, forming a complete through hole through two feed operations. Based on the single-sided feed depth, this embodiment avoids tool collisions caused by excessive feed depth. Simultaneously, controlling the composite tool to align with both the first and second centers ensures coaxiality of the machining on both sides, guaranteeing coaxial connection of the machined hole segments, thereby ensuring the depth accuracy and wall smoothness of the through hole. Through hole machining with a target finishing depth greater than the second cut length can be completed without changing the composite tool, thus improving machining quality and efficiency.

[0072] For example, in this embodiment, a first center and a second center are determined from the preset hole center position. The first center is located at the center of the through hole opening on the upper surface of the workpiece to be processed, and the second center is located at the center of the through hole opening on the lower surface of the workpiece to be processed. The first center and the second center are on the same axis and coaxially opposite each other. The single-sided feed depth is obtained, and the composite tool is controlled to be precisely positioned to the first center. The single-sided feed depth is fed axially from the first center to complete the roughing, finishing, and chamfering of one side of the hole. Then, the composite tool is controlled to move to the second center and feed axially from the second center to complete the processing of the other side, so as to obtain the positioning hole on the workpiece to be processed. The feed speed of the composite tool can be set based on the actual situation. This embodiment does not specifically limit the feed speed of the composite tool.

[0073] By clearly defining the preset hole center position, including the coaxially opposite first and second centers, accurate positioning basis is provided for double-sided machining. This effectively avoids problems such as hole wall misalignment and insufficient coaxiality caused by positioning deviations during on-side tool feed, ensuring the positional accuracy of through-hole machining. At the same time, by determining the single-sided feed depth and controlling the composite tool to feed axially from the first and second centers at that depth, it ensures that roughing, finishing, and chamfering can all complete the corresponding machining processes in a single feed, while avoiding risks such as tool collision and incomplete machining caused by excessive feed depth. This enables the machining of excessively deep positioning holes, improves the efficiency and pass rate of through-hole machining, and reduces machining costs and workpiece scrap rate.

[0074] In a feasible embodiment, step B32 further includes step B321: obtaining the chamfering depth of the chamfering tool of the composite tool, and using the sum of the first cutting length of the roughing tool, the second cutting length of the finishing tool, and the chamfering depth of the composite tool as the single-sided feed depth.

[0075] It should be noted that the chamfering depth refers to the distance that the chamfering tool in a compound tool needs to feed axially when chamfering at the opening of a hole.

[0076] In double-sided machining, each side requires independent roughing, finishing, and chamfering processes. The composite tool begins its feed from the workpiece surface. First, the roughing tool contacts the workpiece and drills to a depth of the first cut length, completing the roughing. Then, the finishing tool enters the roughened section and continues drilling to a depth of the second cut length, completing the finishing. Finally, the chamfering tool contacts the edge of the hole and drills to the chamfering depth, completing the chamfering. Therefore, the total feed distance from the workpiece surface to the chamfering depth is exactly equal to the sum of the first cut length, the second cut length, and the chamfering depth. This single-sided feed depth ensures that during the machining of each side, the roughing, finishing, and chamfering tools work sequentially within their respective effective lengths, and the chamfering tool only contacts the hole opening after finishing, avoiding mismachining and ensuring that the machining of each side is complete and meets the requirements in double-sided machining.

[0077] To better understand this embodiment, refer to Figure 4 and Figure 5 The process of machining using a composite tool in this embodiment is briefly described below, and references are made to... Figure 6 Here is a brief explanation of the conventional machining process using three cutting tools: Let's take a target hole diameter of 4mm as an example for illustration: (Refer to...) Figure 4 , Figure 4 The diagram shows a composite tool for roughing workpiece G using a drill bit. The composite tool used for roughing has a 140° taper angle and a φ3.9 drill bit. The rotational speed of the composite tool can be S9000-S13000, the feed rate of the composite tool can be F1000-F1800, and the depth of cut of the composite tool can be 0.05mm-0.16mm.

[0078] Reference Figure 5 , Figure 5 The diagram illustrates the chamfering process of a composite cutting tool for chamfering the opening corresponding to workpiece G. The composite cutting tool uses a reamer of φ4 and a chamfering cutter at a 45° angle. The tool's rotational speed is S9000-S13000 RPM, feed rate is F500-F800 RPM, and depth of cut is 0.05mm-0.1mm. The machining path is as follows: Figure 5 .

[0079] In the composite cutting tool, the 140° cone at the tip of the tool head is a symmetrical guiding structure. The cone contacts the surface of the workpiece or the pre-drilled center hole, providing radial support before the cutting force is fully established, ensuring that the composite tool is aligned with the center of the preset hole. Then, a 3.9mm diameter drill bit begins its work, removing most of the material from the hole through rotational and axial feed motions. The drill bit undertakes the main material removal task, leaving a uniform and small allowance for finishing. After the drill bit, a 4mm diameter reamer (finishing cutter) performs micro-cutting on the drilled 3.9mm initial hole. Through the precision scraping of the reamer, the hole diameter is precisely machined to the tolerance requirements, and the hole wall is finished, achieving higher dimensional accuracy, cylindricity, and lower surface roughness. After the reamer, a chamfering cutter performs chamfering. The chamfering cutter has a 45° bevel angle and contacts the edge of the hole, removing burrs generated during drilling and reaming in one pass, and creating a uniform 45° chamfer, facilitating assembly and improving the appearance and safety of the parts. The diameter of the shank in a composite tool can be larger than that of a finishing tool.

[0080] In this embodiment, when using the same composite tool for machining, the rotational speed and feed rate during roughing can differ from those during finishing and chamfering. This embodiment does not impose specific limitations on these differences. This embodiment integrates the cutting functions of drilling, reaming, and chamfering into a single tool, i.e., a composite tool. The machining of the positioning hole is completed in one pass through axial feed, optimizing the machining process from three separate tools to a single tool, effectively reducing tooling costs.

[0081] The composite tool in this embodiment is a special tool that integrates guiding, roughing, finishing and deburring functions. In one clamping and one axial feed process, it continuously and coaxially completes all the forming processes of a precision positioning hole in the order of positioning, drilling, reaming and chamfering, thereby improving the processing efficiency while ensuring accuracy and quality.

[0082] Refer to Figure 6 A comparison will be made with this embodiment. Figure 6 The processing steps using three different tools are shown separately: Figure 6 P1 in the diagram shows a roughing operation performed by the first cutting tool J1, for example, Figure 6 The spiral trajectory shown in P1 is the roughing trajectory of the first tool. For example, when using the first tool (which can be a single drill bit) for roughing, the rotational speed of the first tool can be S10000-S15000, the feed rate can be F1000-F1500, and the depth of cut can be 0.05mm-0.1mm.

[0083] Figure 6 P2 in the diagram shows a schematic of the second tool J2 performing finishing. For example, the second tool (which can be a separate reamer) is used for finishing. The rotational speed of the second tool can be S12000-S15000, the feed rate can be F500-F1000, and the depth of cut can be 0.03mm-0.05mm (the allowance after roughing).

[0084] Figure 6P3 in the diagram illustrates the chamfering process performed by the third tool J3. This third tool (a separate chamfering tool) removes burrs. The rotational speed of this third tool can be S12000-S14000, the feed rate can be F1000-F2000, and the depth of cut can be 0.1mm-0.5mm. It can be seen that using three separate tools for machining the positioning hole is cumbersome, requiring multiple tool changes during the machining of the same positioning hole, resulting in low efficiency. Therefore, this embodiment uses a composite tool to machine the positioning hole, which not only improves machining efficiency but also enhances machining commands. Because the roughing tool, finishing tool, and chamfering tool in the composite tool are coaxially arranged, the resulting positioning hole is also coaxially machined, thus improving machining quality. Combining the tools avoids frequent tool changes between roughing, finishing, and chamfering processes, shortening the overall machining cycle. Furthermore, since individual tools need to be purchased, maintained, and stored separately, combining them into a single tool (composite tool) reduces the number of tools required, saving costs. Furthermore, the tool magazine space of the machine tool equipment is optimized, allowing for the accommodation of more other types of tools and simplifying factory inventory management. In addition, the tool changing process may introduce workpiece positioning errors or vibrations, affecting dimensional accuracy. After merging the tools, the cumulative errors caused by repositioning the tool are reduced, ensuring more consistent machining positions of the positioning holes (especially in precision parts); and the on-site operator only needs to monitor the status of one tool (composite tool) (such as wear or lifespan), reducing the workload of debugging and maintenance.
