[0065] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.
[0066] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same category, and do not limit the number of objects. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.
[0067] Next, in conjunction with the accompanying drawings, the turning processing method, device, and electronic device provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.
[0068] When turning a workpiece, in some scenarios, such as when processing plastic materials, it is easy for chips to wind around the workpiece or the tool.
[0069] In order to reduce chip entanglement, the related art performs chip breaking by selecting a cutting tool. Due to different machining conditions and significant differences in tool models, this method requires high proficiency from the operator in tool selection and deep selection experience. Moreover, during the machining process, impacts are generated, which can easily cause fatigue failure of the cutting tool and result in poor stability.
[0070] In an embodiment of the present application, by using program instructions to change the turning machining operation, through a vibration turning principle, continuous turning is replaced with interrupted turning, thereby achieving turning chip breaking.
[0071] See Figure 1 , Figure 1 which is a flowchart of a turning machining method provided by an embodiment of the present application. As Figure 1 shown, the turning machining method includes:
[0072] Step 101, the machining equipment successively performs turning machining on the workpiece in a first machining stage using a first machining method and in a second machining stage using a second machining method;
[0073] wherein, the first machining stage and the second machining stage are different machining stages, the first machining method is the machining method corresponding to the feed movement, the second machining method is the machining method including a feed movement and a retraction movement, and the second machining stage is the machining stage where chip entanglement occurs in the machining equipment.
[0074] The machining equipment can be equipment for turning machining, such as a machining tool.
[0075] The first machining method can be the machining method corresponding to the feed movement, and the main purpose of this machining method is machining; the second machining method takes into account the influence of chip entanglement and requires chip breaking treatment. Therefore, during the machining process, it includes a feed movement and a retraction movement.
[0076] In some alternative embodiments, in order to ensure the machining progress while breaking chips, the feed distance corresponding to the feed movement in the second machining method can be set to be greater than the retraction distance corresponding to the retraction movement.
[0077] In some alternative embodiments, in order to improve the chip breaking effect, the retraction distance of the retraction movement in the second machining method can be set to be greater than a preset value.
[0078] In some alternative embodiments, the second machining method can further include a first sub-machining method and a second sub-machining method. In the first sub-machining method, the feed distance corresponding to the feed movement is greater than the retraction distance corresponding to the retraction movement; in the second sub-machining method, feeding can be performed in segments, that is, after feeding a certain distance, pause for a preset time period and then continue feeding.
[0079] The above specific processing method can be selected according to the requirements such as the type of workpiece to be processed, the processing progress, and the degree of chip entanglement.
[0080] Optionally, before the processing equipment performs turning on the workpiece using the second processing method in the second processing stage, the method further includes:
[0081] The processing equipment determines the processing parameters corresponding to the second processing method according to the processing type of the workpiece;
[0082] The processing equipment performing turning on the workpiece using the second processing method in the second processing stage includes:
[0083] The processing equipment performs turning on the workpiece using the second processing method according to the processing parameters in the second processing stage.
[0084] The processing type of the workpiece can be a processing type determined according to the shape, material, etc. of the workpiece.
[0085] For example, when the processing trajectory corresponding to the contour of the workpiece includes a straight line, the processing type of the workpiece can be a straight line type; when the processing trajectory corresponding to the workpiece contour includes an arc, the processing type of the workpiece can be an arc processing type; when the processing trajectory corresponding to the workpiece contour includes a thread, the processing type of the workpiece can be a thread processing type.
[0086] For example, if the workpiece is a cylindrical shaft part, the processing type can include arc processing.
[0087] Corresponding to each different processing type, different processing parameters need to be set, such as feed speed, cutting depth, processing path, etc.
[0088] Based on the processing parameters corresponding to the processing type, the workpiece is processed. Since the second processing type includes a feed action and a retraction action, the processing progress and the chip breaking effect can be considered simultaneously.
[0089] Optionally, when the processing type of the workpiece includes the first processing type, the processing parameters include at least one of a feed path, a retraction path, a feed angle, a retraction angle, a feed distance corresponding to the feed action, and a retraction distance corresponding to the retraction action;
[0090] When the processing type of the workpiece includes the second processing type, the processing parameters include at least one of a first cut depth, a minimum cut depth, a taper, a thread tooth height, a retraction distance, a retraction height, a finishing allowance, a feed distance, a retraction distance, an angle of the thread tooth profile, a retraction angle, a finishing repetition number, and a skew retraction height coefficient.
[0091] Among them, the first machining type may include at least one of an arc machining type and a linear machining type; the second machining type may be a thread machining type.
[0092] For the parameters corresponding to the first machining type, among them, the feed path can be understood as the path corresponding to the machining trajectory; the feed angle and the retraction angle can be understood as the angles between the tool and the workpiece surface during feeding or retraction; the feed distance can be understood as the distance that the tool feeds and moves along the machining path on the workpiece surface, and the retraction distance is the distance that the tool retracts along the machining path.
[0093] For the parameters corresponding to the second machining type, among them:
[0094] The first cut depth can be understood as the first feed amount;
[0095] The minimum cut depth can be understood as the minimum feed amount. In some embodiments, the cut depth T per cut can be taken as T = E * N 0.5 , where E represents the first cut depth and N represents the number of cycles. If the feed amount per time is less than T, the feed amount is clamped at T and takes the value of T;
[0096] Taper: Diameter programming, the set value includes positive and negative. When set to 0, it is a straight thread cutting;
[0097] Retraction distance: In some embodiments, the set value is a multiple of the lead;
[0098] Retraction height: Diameter programming, indicating the retraction height per cut cycle. In some embodiments, the set value is a positive number;
[0099] Feed distance: The feed and movement distance along the machining trajectory. In some embodiments, it can be set as a multiple of the lead. For example, retraction and chip breaking are performed once every set value multiple of the lead distance. The set value is a positive integer. For example, the default value is set to 2;
[0100] Retraction distance: The retraction distance along the machining trajectory. In some embodiments, it can be set as a multiple of the lead. For example, each time chip breaking occurs, the retraction distance is the set value multiple of the lead distance. The set value is a positive integer. For example, the default value is set to 1;
[0101] Angle of the thread profile: Thread tooth angle (tip angle). For example, it is set to 80°, 60°, 55°, 30°, 29°. For example, the default value is set to 60°;
[0102] Retraction angle: For example, the default value is set to 45°;
[0103] Number of finishing repetitions: The number of times of final dimension finishing repetition. For example, the default value is set to 1;
[0104] The height coefficient of chip breaking with oblique retraction and oblique advancement. In some embodiments, the oblique retraction height is a multiple of the tooth height set, for example, taking any value in the range of 1.2 - 1.5, such as setting the default value to 1.3.
[0105] Implement different types of machining based on the above machining parameters.
[0106] Optionally, in the second machining stage, the machining equipment performs turning on the workpiece according to the machining parameters and using the second machining method, including:
[0107] In the second machining stage, the machining equipment performs turning on the workpiece according to the machining parameters and using at least one of the following machining methods:
[0108] The tool of the machining equipment feeds a first distance along the machining path and retracts a second distance, and the first distance is greater than the second distance;
[0109] The tool of the machining equipment feeds in sequence in the direction of a first preset angle and retracts in the direction of a second preset angle;
[0110] The tool of the machining equipment feeds a third distance in sequence in the direction of a third preset angle, retracts a fourth distance in the direction of a fourth preset angle, retracts a fifth distance in the direction of a fifth preset angle, feeds the fourth distance in the direction of the fourth preset angle, and the third distance is greater than the fifth distance;
[0111] The tool of the machining equipment feeds a sixth distance along the machining path in sequence, pauses feeding for a first preset time period, and then feeds a seventh distance along the machining path;
[0112] During the rotation of the workpiece, the tool of the machining equipment feeds an eighth distance along the machining path in sequence, pauses feeding for a second time period, and then feeds a ninth distance along the machining path, where the second time period is the time duration for the workpiece to rotate a preset number of turns;
[0113] Wherein, the angle is the angle between the feeding path or the retracting path and the surface of the workpiece.
[0114] Among them, the above machining methods can be applied to the linear type or the arc type. The second machining method can specifically include the following five machining methods:
[0115] The first one is chip breaking by feeding and retracting along the machining path.
[0116] Such as Figure 2As shown, (a) is a general tool path without turning chip breaking enabled, and (b) is the tool path after enabling the turning chip breaking function. As shown in (b), the tool feeds along the machining path on the workpiece surface for a first distance, then retracts for a second distance (K), and then continues to feed for a moving distance l. When the first distance is greater than the second distance, the overall machining progress remains in the feeding state, which can improve the machining progress.
[0117] The above method can be applied to single-axis feeding. For example, it can be applied to external cylindrical turning machining.
[0118] The second is to feed along a first preset angle and retract along a second preset angle.
[0119] Among them, the first preset angle can be the angle between the tool and the workpiece surface during feeding. This angle can take any angle value from 0° to 90°. In some alternative embodiments, for example, it can take the values of 0° and 45°.
[0120] The second preset angle can be the angle between the tool and the workpiece surface during retraction. This angle can take any angle value from 0° to 90°. In some alternative embodiments, for example, it can take the values of 0° and 45°.
[0121] In some alternative embodiments, the first preset angle and the second preset angle can be the same or different.
[0122] As Figure 3 shown, (a) is a general tool path without turning chip breaking enabled, and (b) is the tool path after enabling the turning chip breaking function. As shown in (b), the tool feeds along the workpiece surface (the first preset angle is 0°) for a moving distance 1, and then retracts for a distance K along the retraction angle A (i.e., the second preset angle).
[0123] The above method can be applied to parts with higher hardness, such as stainless steel, etc. The above machining method can improve the surface finish of chip breaking machining.
[0124] The third is to feed and retract multiple times along different angular directions.
[0125] As Figure 4 shown, (a) is a general tool path without turning chip breaking enabled, and (b) is the tool path after enabling the turning chip breaking function. As shown in (b), the tool successively feeds along the workpiece surface for a moving distance l, retracts for a distance K along the retraction angle A, retracts for a distance B along the direction parallel to the workpiece surface, and feeds along the same angle A as the retraction angle. The above feeding path and retraction path form a rhombus.
[0126] This machining path is in Figure 3Based on the shown processing method, a retraction action is added. In this way, by means of the retraction point of the secondary processing, the surface finish can be improved.
[0127] The fourth method is to pause for chip breaking for a period of time after machining for a certain period (or a certain distance, or a certain stage), and then continue the feed machining.
[0128] For example, every 5 s of machining, pause for 1 s and then continue machining for 5 s and pause for 1 s; it can also be that for every feed movement distance A, pause for 1 s, continue the feed movement distance B, and pause for 1 s.
[0129] In this way, chip breaking is achieved through feed and short-term feed stop, which can be applicable to chip breaking of materials with low plasticity, such as 7-series aluminum alloy materials, etc.
[0130] The fifth method is to pause the feed for chip breaking according to the number of turns of the workpiece rotation.
[0131] During the machining process, the workpiece rotates around the axis. After machining for a certain period (or a certain distance, or a certain stage), the feed is paused. After the workpiece rotates 5 turns, the feed is continued.
[0132] For the fourth and fifth processing methods, reference can be made to Figure 5 as shown. (a) is the general tool path without turning chip breaking enabled, and (b) is the tool path after the turning chip breaking function is enabled. As shown in (b), after the tool feeds and moves a distance l, it pauses for a time K (or pauses machining during the period when the workpiece rotates K turns), and then continues to feed. By feeding in segments in the above manner, the purpose of chip breaking is achieved.
[0133] During actual use, it can be set to the corresponding five modes and the corresponding parameters are set. For example, in the linear machining type, the above five modes can be in turn:
[0134] P1: G1401 P1 X(U)_Z(W)_I_K_F_(Q) Retract for chip breaking along the machining path;
[0135] P2: G1401 P2 X(U)_Z(W)_I_K_A_F_(Q) Retract for chip breaking with oblique feed and oblique retraction;
[0136] P3: G1401 P3 X(U)_Z(W)_I_K_A_B_F_(Q) Diamond-shaped retract for chip breaking;
[0137] P4: G1401 P4 X(U)_Z(W)_I_K_F_ Pause for chip breaking by time;
[0138] P5: G1401 P5 X(U)_Z(W)_I_K_F_ Pause for chip breaking by the number of turns;
[0139] Among them, G represents the chip breaking instruction, P represents the chip breaking processing method, X(U) represents the end coordinate of the X-axis, supporting absolute instruction / incremental instruction; Z(W) represents the end coordinate of the Z-axis, supporting absolute instruction / incremental instruction; I represents the feed distance; among P1 to P3, K represents the retraction distance, and among P4 and P5, K represents the pause time or the number of turns of the workpiece rotation during the pause time; A represents the oblique retraction angle (the positive and negative values of A represent internal and external circle machining); B represents the diamond retraction distance; Q represents the percentage of the retraction action speed, for example, the default value is set to 100%; F represents the feed speed.
[0140] For the above five methods, one or more combinations can be selected according to the actual workpiece machining profile, workpiece material, machining quality requirements, etc. The code instructions corresponding to the above multiple machining methods can be modal or non-modal.
[0141] Optionally, the machining type of the workpiece includes an arc machining type, and the workpiece includes an arc surface;
[0142] Both the first preset angle and the second preset angle are the angles between the arc surface and the normal of the arc; or,
[0143] The first preset angle is the angle between the arc surface and the tangent of the arc, and the second preset angle is the angle between the arc surface and the normal of the arc.
[0144] In the case where the first machining type is an arc type, the first preset angle can be along the arc normal, and the second preset angle can be along the arc normal or tangent.
[0145] Based on the arc-type workpiece, the parameters corresponding to the above five machining methods are as follows:
[0146] P1: G1402(G1403)P1 X(U)_Z(W)_I_K_R_F_(Q_) Chip breaking along the arc of the machining path
[0147] P2: G1402(G1403)P2 X(U)_Z(W)_I_K_F_(Q_) Chip breaking along the normal arc and straight retraction and advancement

[0151] Wherein: G represents the chip breaking instruction, P represents the chip breaking processing method, X(U) represents the end coordinate of the X-axis, supporting absolute instruction / incremental instruction; Z(W) represents the end coordinate of the Z-axis, supporting absolute instruction / incremental instruction; I represents the feed movement distance (determining the chip breaking frequency and chip breaking length); K represents the retraction distance, and to ensure the chip breaking effect, it can take a value greater than 1.3*F; F represents the feed speed; R represents the arc radius; in the chip breaking processing methods corresponding to P2 and P3, the positive and negative of K represent the positive and negative of the normal direction, with the direction pointing to the center of the circle being positive; in the chip breaking processing methods corresponding to P4 and P5, K represents the pause time or the number of turns of the workpiece rotation during the pause period; Q represents the percentage of the retraction action speed. For example, the default value is set to 100%.

[0153] The tool of the processing equipment feeds the tenth distance along the processing path in sequence in the second processing stage, retracts the eleventh distance after retracting along the angle of the thread profile, and feeds the twelfth distance along the direction of the sixth preset angle;
[0154] Wherein, the tenth distance is greater than the eleventh distance, and the angle is the angle between the feed path or the retraction path and the surface of the workpiece.
[0155] For the thread processing type, the processing path can be referred to Figure 6 as shown. (a) is the tool path without thread chip breaking enabled, and (b) is the tool path after the thread chip breaking function is enabled. As shown in (b), after the tool feeds the moving distance l along the surface of the workpiece and retracts along the direction corresponding to the thread profile angle, it retracts the distance K, and then feeds along the preset angle, which can be equal to the thread profile angle. The above feed and retraction paths form a trapezoid.
[0156] Among them, the parameter settings of the thread chip breaking instruction are, for example:
[0157] G1404 X(U)_Z(W)_F_A_E_T_H_D_R_B_(I_K_Q_P_C_M_)
[0158] Among the above parameters, G represents the chip breaking instruction, X(U) represents the end coordinate of the X-axis, supporting absolute instruction / incremental instruction; Z(W) represents the end coordinate of the Z-axis, supporting absolute instruction / incremental instruction; F represents the lead of the thread; E represents the first cutting depth; T represents the minimum cutting depth; A represents the taper; H represents the thread height; D represents the retraction distance; R represents the retraction height; B represents the finishing allowance; l represents the feed movement distance; K represents the retraction distance; Q represents the thread profile angle; P represents the retraction angle; C represents the number of finishing repetitions; M represents the inclined retraction height coefficient.
[0159] Based on the above parameter settings, chip breaking machining of the thread type can be achieved.
[0160] Through the above method, the problem of chip entanglement in thread turning can be reduced, and the correct thread profile (i.e., no thread disorder) can be ensured during retraction, which can be applied to various thread fixed cycle machining scenarios.
[0161] For the above multiple machining types and the multiple machining methods corresponding to each type, the corresponding machining type can be selected according to the actual situation, and one or more of the machining methods can be selected for combined machining.
