The final adjusted CNC parameters are then used as the target CNC parameters, and the final adjusted cutter parameters are used as the target cutter parameters.

[0014] In one embodiment, adjusting the initial CNC parameters when any one of the parameters—surface flatness, thickness, or milling cutter wear—does not reach a preset standard range includes:

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0040] In this embodiment, a workpiece milling method is provided. This embodiment uses the application of this method to a computer device as an example for illustration. It can be understood that this method can also be applied to a server, and can also be applied to a system including a computer device and a server, and can be implemented through the interaction between the computer device and the server.

[0041] Figure 1 This is a flowchart illustrating the workpiece milling method provided in an embodiment of this application. The method is applied in a computer device. In one embodiment, such as... Figure 1 As shown, it includes the following steps:

[0042] S101, obtain initial CNC parameters and initial milling cutter parameters; wherein, the initial CNC parameters are used to indicate the method of milling the simulated workpiece.

[0043] Initial milling cutter parameters are used to determine the milling cutter used to mill the simulated workpiece.

[0044] S102, based on the initial CNC parameters and initial milling cutter parameters, performs a milling simulation test on the simulated workpiece to be milled until the workpiece reaches the preset thickness range after milling.

[0045] S103, obtain the surface flatness and thickness of the milled workpiece within the preset thickness range, as well as the milling cutter wear.

[0046] The surface flatness of the milled workpiece is defined as the maximum absolute distance from all points on the workpiece surface to the reference plane. The thickness dimension of the milled workpiece includes at least one of its length, width, height, or radius. The cutter wear indicator is used to indicate the degree of wear on the milling cutter.

[0047] In some embodiments, the wear of the milling cutter can be obtained by acquiring images of the milling cutter before and after use, or by directly detecting the milling cutter using a tool setter; the specific method is not limited.

[0048] S104, based on surface flatness, thickness, and milling cutter wear, adjusts the initial CNC parameters and initial milling cutter parameters to determine the target CNC parameters and target milling cutter parameters.

[0049] S105, determine the target milling cutter using the target milling cutter parameters, and use the target CNC parameters and the target milling cutter to mill the actual workpiece to be milled.

[0050] The actual workpiece to be milled and the simulated workpiece to be milled belong to the same category.

[0051] The workpiece milling method provided in this embodiment uses initial CNC parameters and initial milling cutter parameters to indicate the milling method for a simulated workpiece. A milling simulation experiment is conducted on the simulated workpiece until it reaches a preset thickness range. Based on the surface flatness and thickness of the milled workpiece within the preset thickness range, as well as the milling cutter wear, the initial CNC parameters and initial milling cutter parameters are adjusted to determine target CNC parameters and target milling cutter parameters. The target milling cutter parameters are then used to determine the target milling cutter, and the actual workpiece is milled using these target CNC parameters and the target milling cutter. Compared to traditional techniques that rely on the experience of milling engineers to set CNC parameters, resulting in poor milling quality, this embodiment, through milling simulation experiments, considers parameters affecting milling quality such as the surface flatness, thickness, and milling cutter wear of the milled workpiece. Adjusting the initial CNC parameters and initial milling cutter parameters to determine the target CNC parameters and target milling cutter parameters results in higher accuracy and ensures the quality of milling the actual workpiece.

[0052] In one embodiment, the initial CNC parameters include at least one of feed power, cutting edge angle, or workpiece clamping force, wherein the feed power is used to control the milling speed of the simulated workpiece to be milled; the initial milling cutter parameters include at least one of milling cutter diameter or milling cutter material.

[0053] The cutting edge angle is the angle between the milling cutter and the simulated workpiece surface. The workpiece clamping force is the compressive pressure exerted on the simulated workpiece to hold it in place. The milling cutter material includes at least one of high-speed tool steel or cemented carbide.

[0054] In this embodiment, the initial CNC parameters and initial milling cutter parameters are specifically elaborated. The parameters considered are both concise and comprehensive, which improves the efficiency of determining the target CNC parameters and target milling cutter parameters.

[0055] In one embodiment, based on surface flatness, thickness, and cutter wear, initial CNC parameters and initial cutter parameters are adjusted to determine target CNC parameters and target cutter parameters, including:

[0056] If any parameter, such as surface flatness, thickness, or cutter wear, fails to meet the preset standard range, the initial CNC parameters and initial cutter parameters are adjusted. The adjusted CNC parameters and cutter parameters are then used to repeatedly perform milling simulation tests on the simulated workpiece until the surface flatness, thickness, and cutter wear all meet the preset standard range. The final adjusted CNC parameters are then used as the target CNC parameters, and the final adjusted cutter parameters are used as the target cutter parameters.

[0057] Specifically, the preset standard range corresponding to the thickness dimension is more precise than the preset thickness dimension range.

[0058] In some embodiments, if any parameter among surface flatness, thickness, or milling cutter wear does not reach a preset standard range, the initial CNC parameters and initial milling cutter parameters are adjusted, including:

[0059] The initial CNC parameters and initial milling cutter parameters are given a certain range. The milling simulation test is carried out starting from the minimum value in the range. The initial CNC parameters and initial milling cutter parameters are adjusted by continuously increasing them.

[0060] It should be understood that there are no restrictions on how the initial CNC parameters and initial milling cutter parameters are adjusted.

[0061] In this embodiment, considering both the quality issues of the milled workpiece and the wear issues of the milling cutter, the determined target CNC parameters and target milling cutter parameters are used to mill the actual workpiece to be milled, thereby improving the milling quality.

[0062] In one embodiment, if any parameter among surface flatness, thickness, or milling cutter wear does not meet a preset standard range, the initial CNC parameters are adjusted, including:

[0063] If any parameter, such as surface flatness, thickness, or milling cutter wear, fails to meet the preset standard range, the corresponding initial CNC parameters are adjusted based on at least one of the first, second, third, or fourth mapping relationships.

[0064] In this embodiment, adjusting the corresponding initial CNC parameters based on at least one of the first, second, third, or fourth mapping relationships can improve the efficiency of adjusting the initial CNC parameters.

[0065] In one embodiment, the methods for obtaining the first, second, third, and fourth mapping relationships are elaborated. Specifically, a flowchart illustrating the process of obtaining the mapping relationships is shown below. Figure 2 As shown, it includes the following:

[0066] S201, during a historical time period, the sample workpiece to be milled is milled to obtain the relationship between the historical cutting edge entry angle and the historical thickness dimension, which is used as the first mapping relationship.

[0067] The sample workpiece to be milled and the simulated workpiece to be milled belong to the same category.

[0068] S202, obtain the relationship between historical workpiece clamping force and historical thickness dimension, as the second mapping relationship.

[0069] S203, obtain the relationship between historical feed power and historical milling cutter wear as the third mapping relationship.

[0070] S204, obtain the relationship between the historical cutting edge entry angle and the historical surface flatness, as the fourth mapping relationship.

[0071] In this embodiment, based on the historical milling data of the sample workpiece to be milled, a relationship is established between three parameters—surface flatness, thickness, and milling cutter wear—and CNC parameters. This relationship is used to adjust the initial CNC parameters, ensuring the accuracy and efficiency of parameter adjustment.

[0072] In one embodiment, before determining the target milling cutter using the target milling cutter parameters, the following steps are included:

[0073] Display the target CNC parameters and target milling cutter parameters and issue a confirmation command;

[0074] Upon receiving a confirmation instruction, the steps are as follows: determine the target milling cutter using the target milling cutter parameters, and then use the target CNC parameters and the target milling cutter to mill the actual workpiece.

[0075] It is worth noting that there can be more than one target CNC parameter and one target milling cutter parameter.

[0076] In this embodiment, confirming the target CNC parameters and the target milling cutter parameters can avoid directly performing the milling step on the actual workpiece to be milled, thus avoiding the consumption of the actual workpiece to be milled. Adding a confirmation step further improves the quality of milling.

[0077] Here, the workpiece milling method provided in this application is described in detail by way of a specific embodiment, including the following implementation process:

[0078] Obtain initial CNC parameters and initial milling cutter parameters; wherein, the initial CNC parameters include at least one of feed power, cutting edge angle of entry, or workpiece clamping force, and the initial milling cutter parameters include at least one of milling cutter diameter or milling cutter material; specifically, the feed power is used to control the milling speed of the simulated workpiece, the cutting edge angle of entry is the angle between the milling cutter and the surface of the simulated workpiece, the workpiece clamping force is the squeezing pressure on the simulated workpiece when fixing it, and the milling cutter material includes at least one of high-speed tool steel or cemented carbide.

[0079] Based on the initial CNC parameters and initial milling cutter parameters, a milling simulation test is conducted on the simulated workpiece to be milled until the workpiece reaches the preset thickness range after milling.

[0080] The system obtains the surface flatness and thickness of the milled workpiece within a preset thickness range, as well as the milling cutter wear. If any parameter, including surface flatness, thickness, or milling cutter wear, fails to meet the preset standard range, the initial milling cutter parameters are adjusted. Furthermore, the corresponding initial CNC parameters are adjusted based on at least one of the first, second, third, or fourth mapping relationships. The adjusted CNC parameters and milling cutter parameters are used to repeatedly perform milling simulation tests on the simulated workpiece until the surface flatness, thickness, and milling cutter wear all reach the preset standard range. The final adjusted CNC parameters are then used as the target CNC parameters, and the final adjusted milling cutter parameters are used as the target milling cutter parameters.

[0081] Specifically, the first, second, third, and fourth mapping relationships can be obtained in advance. The methods for obtaining these relationships include: milling the sample workpiece during a historical time period and obtaining the relationship between the historical cutting edge angle and the historical thickness dimension as the first mapping relationship; obtaining the relationship between the historical workpiece clamping force and the historical thickness dimension as the second mapping relationship; obtaining the relationship between the historical feed power and the historical milling cutter wear as the third mapping relationship; and obtaining the relationship between the historical cutting edge angle and the historical surface flatness as the fourth mapping relationship.

[0082] Display the target CNC parameters and target milling cutter parameters and issue a confirmation command; determine whether to perform climb milling or conventional milling on the actual workpiece to be milled, and select the appropriate parameters from the target CNC parameters and target milling cutter parameters for confirmation;

[0083] Upon receiving a confirmation instruction, the target milling cutter is determined using the target milling cutter parameters, and the actual workpiece to be milled is milled using the target CNC parameters and the target milling cutter.

[0084] Specifically, the simulated workpiece to be milled, the sample workpiece to be milled, and the actual workpiece to be milled belong to the same category.

[0085] The workpiece milling method provided in this application determines the target CNC parameters and target milling cutter parameters through milling simulation experiments, and applies them to the actual milling process of the workpiece to be milled, so as to avoid factors that may affect the milling quality and ensure the quality of milling.

Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.
