[0023] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0024] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0025] In the field of CNC machining of structural components, NC programs usually need to be simulated offline using simulation software before they can be sent to the production site for execution.

[0026] However, due to the significant amount of manual intervention in existing CNC machining processes—such as the need for manual clamping of tool system elements like cutting tools, extension rods, and tool holders onto the machine tool spindle—relying solely on pre-simulated offline operations cannot completely prevent quality and safety incidents during actual machining. Human error, such as an operator incorrectly installing the wrong cutting tool, extension rod, or tool holder, leading to incorrect tool system specifications, or an incorrect tool clamping length resulting in an excessively long or short working length, can easily cause abnormal tool breakage during machining or collisions between non-cutting parts of the tool system and the worktable, resulting in significant damage to the cutting tool, parts, and machine tool.

[0027] To address the aforementioned issues, this application provides an automatic construction method, apparatus, equipment, and medium for CNC machining tool systems. The solution described in this application will be detailed below.

[0028] Figure 1 The flowchart of the automatic construction method for CNC machining tool system provided in Embodiment 1 of this application is shown below. Figure 1 The automatic construction method for a CNC machining tool system may include the following steps:

[0029] S11. Real-time acquisition of data during CNC machining.

[0030] The data in the CNC machining process refers to the data released by the CNC machining data acquisition platform.

[0031] It should be noted that the CNC machining tool system constructed in this embodiment does not directly participate in data acquisition, but obtains real-time data acquisition of the tool machining process by subscribing to data published by the CNC machining data acquisition platform.

[0032] In the specific implementation process, real-time data acquisition of the machining process is obtained by subscribing to the data released by the CNC machining data acquisition platform.

[0033] For example, during the CNC machining of a certain part, the data stream, including tool-related information, can be obtained in real time by subscribing to platform data.

[0034] S12. Determine tool data information based on data from the CNC machining process. Tool data information includes tool drawing number, tool holder drawing number, and clamping length.

[0035] The tool drawing number identifies the tool currently being machined and can be used to determine the tool's geometric parameters. The tool holder drawing number identifies the tool holder currently being machined and can be used to determine the tool holder's geometric parameters. The clamping length refers to the clamping length of the tool system currently being machined, i.e., the offset distance from the tool tip to the spindle end face, which can be used to determine the assembly position of the tool system. The tool drawing number, tool holder drawing number, and clamping length are all indispensable information.

[0036] In the specific implementation process, the data acquired in real time during the machining process is analyzed to extract the essential information required to establish the tool system model, including the tool drawing number, tool holder drawing number, and clamping length.

[0037] For example, to construct a CNC machining tool system, this embodiment acquires data streams including tool-related information during the current CNC machining process in real time, and parses the tool drawing number GXLZY2GNT / 12*14*40R3, tool holder drawing number BBT50-MEGA13N-90, and clamping length used in the current machining process. ,in This indicates the clamping length of the tool system.

[0038] In one embodiment, the tool data information may further include an extension rod drawing number, which is used to identify the extension rod currently being machined and can correspondingly determine the geometric parameter information of the extension rod.

[0039] It should be noted that extension rods are not always used during the machining process. Generally, when the working length of the tool is insufficient to machine the features of the part, extension rods are used to connect the tool and the tool holder to extend the working length of the tool. Therefore, the extension rod drawing number is optional information.

[0040] For example, this embodiment also obtains the extension rod drawing number ST20-NBS13-60 used in the current machining process by acquiring the data stream including tool-related information in real time during the current CNC machining process.

[0041] S13. Based on the tool drawing number and tool holder drawing number, retrieve and obtain the corresponding geometric parameter information from the preset tool system file.

[0042] The preset tool system file refers to a pre-created *.csv file containing geometric parameter information for all tools, extension rods, and tool holders. This file allows for real-time retrieval of the corresponding geometric parameter information for each tool, extension rod, and tool holder. The geometric parameter information includes general geometric parameters for the tools and geometric point information for the tool holders.

[0043] It is understood that in this embodiment, retrieving and obtaining the corresponding geometric parameter information from the preset tool system file based on the tool drawing number and the tool holder drawing number means: retrieving and obtaining the general geometric parameter information corresponding to the tool drawing number from the tool CSV file based on the tool drawing number, and retrieving and obtaining the geometric point information corresponding to the tool holder drawing number from the tool holder CSV file based on the tool holder drawing number.

[0044] In the specific implementation process, based on the tool drawing number obtained in step S12, the tool information used for the current machining is retrieved from the tool CSV file, and its corresponding general geometric parameter information, including the tool diameter, is obtained. Tool clamping diameter Cutting tool bottom angle radius tool taper Cutting blade length Tool length .

[0045] Furthermore, based on the tool holder drawing number obtained in step S12, the tool holder information currently used in machining is retrieved from the tool holder CSV file, and its corresponding geometric point information is obtained, including the coordinates of tool holder contour point 1. 2. Coordinates of tool holder outline point 2 3 coordinates of the tool holder outline point 4 coordinates of the tool holder outline point 5 coordinates of the tool holder outline point 6 coordinates of the tool holder outline point 7 coordinates of the tool holder outline point 8 coordinates of the tool holder outline points 9 coordinates of the tool holder outline point Coordinates of point 10 on the tool sheath outline .

[0046] It should be noted that since the tool holder model is more complex than the tool model, and the tool holder is not a key element in forming the features of the part during the machining process, the geometric accuracy requirement of its model is not high. In order to simplify the definition of the tool holder model, this embodiment uses a rotary element composed of 10-point polyline drawing to define the tool holder contour.

[0047] For example, the current tool drawing number is GXLZY2GNT / 12*14*40R3. The general geometric parameters of the tool can be retrieved from the tool CSV file: tool diameter... Tool clamping diameter Tool base corner radius tool taper , blade length Tool length The current tool holder drawing number is BBT50-MEGA13N-90. The coordinates of tool holder contour point 1 are retrieved from the tool holder CSV file. 2. Coordinates of tool holder outline point 2 3 coordinates of the tool holder outline point 4 coordinates of the tool holder outline point 5 coordinates of the tool holder outline point 6 coordinates of the tool holder outline point 7 coordinates of the tool holder outline point 8 coordinates of the tool holder outline points 9 coordinates of the tool holder outline point Coordinates of point 10 on the tool sheath outline .

[0048] In one embodiment, step S13 may further include: retrieving and obtaining the geometric parameter information of the extension rod from a preset tool system file based on the extension rod drawing number.

[0049] Specifically, if extension rods are used, the system retrieves the information of the extension rod currently being processed from the extension rod CSV file based on the read extension rod drawing number, and obtains its corresponding general geometric parameters, including the extension rod diameter. and extension rod length .

[0050] For example, if the current extension rod drawing number is ST20-NBS13-60, the diameter of the extension rod can be retrieved. Length of extension pole .

[0051] S14. Based on the geometric parameter information, establish the tool geometric model and the tool holder geometric model respectively.

[0052] Among them, the tool geometry model refers to the three-dimensional model of the tool constructed in the open-source simulation engine through parametric modeling, and the tool holder geometry model refers to the three-dimensional model of the tool holder constructed through the polyline method.

[0053] In the specific implementation process, this embodiment can construct a piecewise function of the tool profile in the first quadrant of the tool tip coordinate system based on the tool's geometric parameter information, and generate a tool geometric model based on the piecewise function; and determine the rotational element of the tool holder profile in the first quadrant of the tool holder coordinate system based on the tool holder's geometric parameter information, and generate a tool holder geometric model based on the rotational element.

[0054] Please see Figure 2 , Figure 2 This is a schematic diagram illustrating the construction of a tool geometry model based on the tool's geometric parameter information provided in this embodiment, as shown below. Figure 2 As shown, this embodiment can construct a tool geometry model in an open-source simulation engine based on the tool's general geometric parameter information using a parametric modeling approach. First, a function of the tool profile in the first quadrant of its own tool tip ZOX coordinate system is constructed. ,when hour:

[0060] Secondly, the tool profile is circumscribed in the first quadrant of its own tool tip ZOX coordinate system by a function. The tool geometry model is obtained by rotating the axis 360°.

[0061] For example, the tool currently in use, part number GXLZY2GNT / 12*14*40R3, is a bullnose end mill with a bottom angle of 3mm. In this embodiment, the tool profile is first constructed as a function in the first quadrant of its own tool tip ZOX coordinate system. :

[0062] (2-1)

[0063] Therefore, through the tool profile in the first quadrant of its own tool tip ZOX coordinate system... Around The tool geometry model is obtained by rotating the axis 360°.

[0064] Please see Figure 3 , Figure 3 A schematic diagram illustrating the construction of a tool holder geometric model based on the tool holder's geometric parameter information provided in this embodiment is shown below. Figure 3 As shown, this embodiment can construct the geometric model of the tool holder in an open-source simulation engine based on the geometric point information of the tool holder and using the polyline modeling method.

[0065] Specifically, connect the coordinates of the tool holder contour point 1 in sequence. 2. Coordinates of tool holder outline point 2 3 coordinates of the tool holder outline point 4 coordinates of the tool holder outline point 5 coordinates of the tool holder outline point 6 coordinates of the tool holder outline point 7 coordinates of the tool holder outline point 8 coordinates of the tool holder outline points 9 coordinates of the tool holder outline point coordinates of point 10 on the tool holder profile Construct the tool holder profile in the first quadrant of the ZOX coordinate system at its bottom center, and rotate around it. The axis rotates 360° to generate the geometric model of the tool holder.

[0066] For example, the coordinates of tool holder contour point 1 are connected sequentially. 2. Coordinates of tool holder outline point 2 3 coordinates of the tool holder outline point 4 coordinates of the tool holder outline point 5 coordinates of the tool holder outline point 6 coordinates of the tool holder outline point 7 coordinates of the tool holder outline point 8 coordinates of the tool holder outline points 9 coordinates of the tool holder outline point coordinates of point 10 on the tool holder profile Obtain the rotation element of the tool holder profile in the first quadrant of the ZOX coordinate system at its bottom center, and rotate this rotation element around... The axis can rotate 360°, and the geometric model of the tool holder can be built in an open-source simulation engine.

[0067] In one embodiment, step S14 may further include: establishing a geometric model of the extension rod based on the geometric parameter information of the extension rod.

[0068] In the specific implementation process, this embodiment can construct a function of the extension rod profile in the first quadrant of the extension rod coordinate system based on the geometric parameter information of the extension rod, and generate the extension rod geometric model based on the function.

[0069] Please see Figure 4 , Figure 4 A schematic diagram illustrating the construction of the geometric model of the extension rod based on its geometric parameters, as provided in this embodiment, is shown below. Figure 4 As shown, this embodiment can construct the geometric model of the extension rod in an open-source simulation engine based on the geometric parameter information of the extension rod using a parametric modeling approach. First, the first quadrant function of the extension rod's profile in the ZOX coordinate system at its bottom center is constructed. :

[0070] (3)

[0071] In equation (3), Indicates the diameter of the extension rod. This indicates the length of the extension rod.

[0072] Secondly, through functions Around The geometric model of the extension rod is obtained by rotating the shaft 360°.

[0073] For example, if the current extension rod drawing number is ST20-NBS13-60, the diameter of the extension rod can be retrieved. Length of extension pole In this embodiment, the first step is to construct the first quadrant function of the ZOX coordinate system at the center of the bottom of the extension rod. :

[0074] (3-1)

[0075] Therefore, the extension rod profile is expressed as a function in the first quadrant of the ZOX coordinate system at its own tip. Around The geometric model of the extension rod is obtained by rotating the shaft 360°.

[0076] S15. Adjust the clamping position of the tool geometry model relative to the tool holder geometry model, assemble the tool geometry model and the tool holder geometry model to form a tool system assembly, so that the virtual clamping length of the tool system assembly is consistent with the clamping length.

[0077] It should be noted that step S15 is to ensure that the clamping position of the tool in the tool system in the open-source simulation engine is consistent with the actual clamping position. Tool holder , The position is where the tool holder mates with the end face of the machine tool spindle; the actual clamping length is the tool holder... , The distance from the position to the tool tip needs to be adjusted, therefore the clamping depth of the tool in the tool holder needs to be adjusted so that the virtual clamping length equals the actual clamping length. .

[0078] In the specific implementation process, by adjusting the axial position of the tool geometry model within the tool holder geometry model, the distance from the end face of the tool system assembly to the tool tip is made equal to the actual clamping length. .

[0079] In one embodiment, step S15 may further include: adjusting the clamping position of the tool geometry model relative to the extension rod geometry model and the tool holder geometry model, and assembling the tool geometry model, the tool holder geometry model and the extension rod geometry model to form a tool system assembly.

[0080] Please see Figure 5 , Figure 5 This is a schematic diagram of the geometric model of the CNC machining tool system provided in this embodiment, such as... Figure 5 As shown, in the specific implementation process, this embodiment first assembles the extension rod geometric model and the tool holder geometric model (the extension rod is inserted into the tool holder), and then inserts the tool geometric model into the extension rod and tool holder assembly.

[0081] Specifically, based on the actual clamping length Calculate the actual working length of the tool based on the length of the extension rod. :

[0082] (4)

[0083] in, Indicates the length of the extension rod. Indicates the actual clamping length. This indicates the Z-axis coordinate of point 8 on the tool holder profile.

[0084] Furthermore, based on tool length and the actual working length of the cutting tool Determine the clamping position of the tool geometry model in the extension rod and tool holder, i.e., the length of the clamped portion of the tool. .

[0085] Therefore, by making the length of the clamped part of the tool equal to The distance from the blade tip to the end face of the blade sheath is... Even if the virtual clamping length of the tool system assembly is consistent with the clamping length, the construction of the CNC machining tool system is completed.

[0086] For example, the actual working length of the tool for:

[0087] (4-1)

[0088] Therefore, the clamping length of the current tool GXLZY2GNT / 12*14*40R3 in the open-source simulation engine is... .

[0089] This application proposes an automatic construction method for CNC machining tool systems. By constructing a general mathematical model of the tool system, it supports rapid modeling of various types of tools such as milling cutters, drills, and reamers, effectively enhancing the versatility of the tool system. Simultaneously, this method independently stores the geometric parameters of each element, such as the tool, extension rod, and tool holder, in *.csv file format. This not only facilitates unified management of the various elements of the tool system but also improves the convenience of maintaining and updating geometric parameters.

[0090] Furthermore, the tool system model constructed in this application clearly distinguishes between the cutting edge and the tool holder based on the structural characteristics of real machining tools, enabling the model to perform geometric Boolean operations and interference collision detection. The cutting edge can be used to perform Boolean subtraction operations between the tool system and the workpiece to simulate the material removal process; the tool holder, extension rod, and tool sleeve can be used for interference collision detection between the tool system and the workpiece and the machine tool table, providing a real-time simulation model for the CNC machining process of complex parts.

[0091] Based on the above embodiments, Figure 6 This is a structural block diagram of an automatic tool-building device for a CNC machining tool system according to one embodiment of this application, such as... Figure 6 As shown, the automatic construction device 600 for the CNC machining tool system may include: a data acquisition module 610, a tool basic information determination module 620, a geometric information acquisition module 630, a geometric model construction module 640, and a model testing and adjustment module 650.

[0093] In an exemplary embodiment, the tool basic information determination module 620 can also be used to retrieve and obtain the geometric parameter information of the extension rod from a preset tool system file based on the extension rod drawing number, and establish a geometric model of the extension rod based on the geometric parameter information of the extension rod.

[0097] In an exemplary embodiment, the geometric parameter information of the tool in the geometric information acquisition module 630 includes one or more of the following: tool diameter, tool clamping diameter, tool base corner radius, tool taper, tool cutting edge length, and tool length.

[0098] In an exemplary embodiment, the geometric parameter information of the extension rod in the geometric information acquisition module 630 includes the extension rod diameter and the extension rod length.

In actual applications, they can be fully or partially integrated into one or more actual carriers. These modules can be implemented entirely in software through processing unit calls, entirely in hardware, or a combination of software and hardware.
