[0054] Step 102, obtaining workpiece size information of the grooved workpiece and the outer rectangular size of the grooved workpiece.

[0055] The groove workpiece may be a workpiece that needs to be grooved. The workpiece size information may be the transverse span size and the longitudinal span size of the groove workpiece. The outer rectangle size may be the size information of the minimum outer rectangle corresponding to the groove workpiece.

[0056] Optionally, the grooved workpiece may be a structure such as a plate, the workpiece size information includes a transverse length value of the workpiece and a longitudinal width value of the workpiece, and the outer rectangle size includes an outer rectangle length value and an outer rectangle width value. The transverse length value of the workpiece may be the maximum length along the transverse direction of the workpiece.

[0058] Step 104 , based on the workpiece size information and the outer rectangular size, the groove workpiece is subjected to point height measurement processing to determine the groove surface height value of the groove workpiece.

[0059] The point-taking height measurement process can be a process of taking points on the groove surface of the grooved workpiece based on the workpiece size information and the outer rectangular size and measuring the height of the taken points. The slope surface height value can be obtained after measuring the height of the taken points, which can reflect the height of the groove surface of the grooved workpiece.

[0060] The case where the height value of the groove surface of the grooved workpiece is determined by taking points and measuring the height of the points according to the workpiece size information and the outer rectangular size includes: taking points on the groove surface of the grooved workpiece according to the workpiece size information, and measuring the height of the taken points according to the outer rectangular size to obtain the groove surface height value of the grooved workpiece.

[0061] Step 106, determining the groove angle compensation value of the grooved workpiece according to the workpiece size information and the groove surface height value.

[0062] The groove angle compensation value can be formed based on the workpiece size information and the groove surface height value, and can be a numerical value for groove angle compensation during the groove processing process.

[0068] In sub-step 202, a machining start position and a machining real-time position of a groove machining line segment of a grooved workpiece are obtained.

[0069] In sub-step 204, the real-time processing direction of the grooved workpiece is determined according to the processing start position and the processing real-time position.

[0070] The groove processing line segment may be an actual trajectory line segment used for groove processing of the groove workpiece. The processing start position may be the processing start point of the groove processing line segment. The processing real-time position may be the processing real-time point of the groove processing line segment. The real-time processing direction may be a parameter formed based on the processing start position and the processing real-time position, and can reflect the processing direction of the groove workpiece at the current moment.

[0072] In sub-step 206, a groove angle compensation value of the grooved workpiece is determined according to the workpiece size information, the groove surface height value and the real-time processing direction.

[0073] The situations in which the groove angle compensation value of the grooved workpiece is determined based on the workpiece size information, the groove surface height value and the real-time processing direction include: determining multiple processing area compensation values ​​based on the workpiece size information and the groove surface height value; determining the groove angle compensation value of the grooved workpiece based on the real-time processing direction and multiple processing area compensation values.

[0074] The processing area may be different areas obtained by dividing the groove workpiece according to different processing directions. The processing area compensation value may be a groove angle compensation value corresponding to the processing directions of different processing areas.

[0075] The specific circumstances of determining multiple processing area compensation values ​​according to the workpiece size information and the groove surface height value include: obtaining the difference between multiple groove surface height values ​​of the grooved workpiece; determining multiple processing area compensation values ​​according to the difference between multiple groove surface height values ​​obtained based on the transverse span size and the longitudinal span size of the grooved workpiece.

[0078] By analyzing the processing start position and real-time processing position on the groove processing line segment of the groove workpiece, the real-time processing direction of the groove workpiece is obtained, and multiple processing area compensation values ​​are determined according to the workpiece size information and the groove surface height value. Then, according to the matching relationship between the real-time processing direction and the processing directions of the processing areas corresponding to the multiple processing area compensation values, the groove angle compensation value of the groove workpiece is determined, thereby improving the specificity of the processing direction of the groove angle compensation, thereby improving the accuracy of the groove angle compensation and ensuring the efficiency of the groove angle compensation.

[0079] Figure 3 , which is a specific flow chart of step 106 in one embodiment.

[0080] In this embodiment, if Figure 3 As shown, step 106 includes sub-steps 302 to 304 .

[0081] In sub-step 302, a plurality of workpiece horizontal slope values ​​are determined according to a workpiece transverse length value, a workpiece longitudinal width value and a plurality of groove surface height values.

[0082] In sub-step 304, a plurality of machining area compensation values ​​are determined according to a plurality of workpiece horizontal slope values.

[0083] The workpiece horizontal slope value can be formed based on the workpiece transverse length value, the workpiece longitudinal width value and multiple groove surface height values, and can reflect the horizontal inclination degree of the groove surface of different processing areas of the grooved workpiece. Optionally, the workpiece horizontal slope value includes a first workpiece horizontal slope value, a second workpiece horizontal slope value and a third horizontal slope value.

[0084] The situations in which multiple horizontal slope values ​​of a workpiece are determined based on the transverse length value of the workpiece, the longitudinal width value of the workpiece and multiple groove surface height values ​​include: determining the first horizontal slope value of the workpiece based on the transverse length value of the workpiece and multiple groove surface height difference values; determining the second horizontal slope value of the workpiece based on the transverse length value of the workpiece, the longitudinal width value of the workpiece and multiple groove surface height difference values; determining the third horizontal slope value of the workpiece based on the longitudinal width value of the workpiece and multiple groove surface height difference values.

[0085] The first workpiece horizontal slope value can be formed based on the workpiece transverse length value and the multiple groove surface height differences along the transverse direction of the workpiece, and can reflect the numerical value of the inclination degree of the groove surface along the transverse direction of the workpiece. The second workpiece horizontal slope value can be formed based on the workpiece transverse length value, the workpiece longitudinal width value and the multiple groove surface height differences along the non-transverse or non-longitudinal direction of the workpiece, and can reflect the numerical value of the inclination degree of the groove surface along the non-transverse or non-longitudinal direction of the workpiece. The third workpiece horizontal slope value can be formed based on the workpiece longitudinal width value and the multiple groove surface height differences along the longitudinal direction of the workpiece, and can reflect the numerical value of the inclination degree of the groove surface along the longitudinal direction of the workpiece.

[0088] Figure 4 , which is a specific flow chart of step 104 in an embodiment.

[0089] In this embodiment, if Figure 4 As shown, step 104 includes sub-steps 402 to 404 .

[0090] In sub-step 402, a height measurement position of a groove surface of the grooved workpiece is determined according to a transverse length value of the workpiece and a longitudinal width value of the workpiece.

[0091] In sub-step 404, a point height measurement process is performed on the groove workpiece according to the outer rectangle size and the groove surface height measurement position to determine the groove surface height value of the groove workpiece.

[0092] The height measurement position of the groove surface can be formed based on the transverse length value and the longitudinal width value of the workpiece, and can reflect the position of the inclination degree of each part of the groove surface. Optionally, the height measurement position of the groove surface includes the edge endpoint, the edge middle point of the groove workpiece, and the edge endpoint and edge middle point of the minimum outer bounding rectangle corresponding to the groove workpiece. The edge middle point can be the middle value of the two edge endpoints.

[0093] The situations of determining the height measurement position of the groove surface of the grooved workpiece according to the transverse length value and the longitudinal width value of the workpiece include: determining the minimum outer rectangle corresponding to the grooved workpiece according to the transverse length value and the longitudinal width value of the workpiece; and determining the height measurement position of the groove surface of the grooved workpiece by the edge end points, the edge middle points of the grooved workpiece and the edge end points and the edge middle points of the minimum outer rectangle corresponding to the grooved workpiece.

[0094] According to the size of the outer rectangle and the height measurement position of the groove surface, the groove workpiece is subjected to point height measurement processing to determine the groove surface height value of the groove workpiece, including: obtaining the height measurement compensation threshold of the groove workpiece; when the length value of the outer rectangle or the width value of the outer rectangle meets the height measurement compensation threshold, according to the height measurement position of the groove surface, the groove workpiece is subjected to point height measurement processing to determine the groove surface height value of the groove workpiece.

[0095] Through the workpiece size information of the groove workpiece, the minimum outer rectangle corresponding to the groove workpiece is obtained, and based on the edge endpoints and edge midpoints of the groove workpiece and the minimum outer rectangle corresponding to the groove workpiece, the groove surface height measurement position of the groove workpiece is obtained, which is convenient for subsequent point measurement of the groove workpiece, and can be adaptively adjusted according to the actual groove processing conditions, effectively improving the scope of application of the groove processing compensation method.

[0096] For example, Figure 5As shown, after analyzing the size of the groove workpiece, the workpiece size information of the groove workpiece is obtained, the maximum coordinate value Xmax in the X direction (i.e. the maximum coordinate value along the longitudinal direction of the workpiece), the minimum coordinate value Xmin (i.e. the minimum coordinate value along the longitudinal direction of the workpiece), the maximum coordinate value Ymax in the Y direction (i.e. the maximum coordinate value along the transverse direction of the workpiece), the minimum coordinate value Ymin (i.e. the minimum coordinate value along the transverse direction of the workpiece); the minimum outer rectangle of the groove workpiece has an X-direction length XL=Xmax-Xmin, a Y-direction length YL=Ymax-Ymin, Xmid=(Xmax+Xmin) / 2, and Ymid=(Ymax+Ymin) / 2.

[0097] To ensure machining efficiency, points are taken on the groove surface of the grooved workpiece according to the workpiece size information, and the height of the taken points is measured according to the size of the outer rectangle, and the height value of the groove surface of the grooved workpiece is obtained as follows: According to the size of the grooved workpiece, it is divided into the following two working conditions: XL < 300mm and YL < 300mm, no point taking height measurement is performed, and no angle compensation is performed; XL ≥ 300mm or YL ≥ 300mm, the positioning machining head takes points on P1, P2, P3, P4, P5, P6, P7, and P8 to measure the height and obtain the Z coordinate of each point.

[0098] Firstly, the real-time processing direction α=arctan[(Yd-Yo) / (Xd-Xo)] of the groove workpiece is obtained through the processing starting position Po(Xo, Yo) and the processing real-time position Pd(Xd, Yd) of the groove processing line segment of the groove workpiece.

[0099] Secondly, according to the workpiece size information and groove surface height value, the situations in which the compensation values ​​of multiple processing areas are determined include:

[0100] 1. According to the transverse length value of the workpiece and the height difference values ​​of the multiple groove surfaces, the horizontal slope value of the first workpiece is determined, and according to the obtained horizontal slope value of the first workpiece, the compensation value of the first processing area is determined as follows:

[0101] K1=(Z1-Z5) / (Xmax-Xmin); β1=arctan(K1)

[0102] 2. According to the horizontal length value of the workpiece, the longitudinal width value of the workpiece and the height difference values ​​of the multiple groove surfaces, the horizontal slope value of the second workpiece is determined, and according to the obtained horizontal slope value of the second workpiece, the compensation value of the second processing area is determined as follows:

[0103] K2=(Z2-Z6) / √[(Xmax-Xmin)^2+(Ymax-Ymin)^2]; β2=arctan(K2)

[0104] K4=(Z4-Z8) / √[(Xmin-Xmax)^2+(Ymin-Ymax)^2]; β4=arctan(K4)

[0105] 3. According to the longitudinal width value of the workpiece and the height difference values ​​of the multiple groove surfaces, the horizontal slope value of the third workpiece is determined, and according to the obtained horizontal slope value of the third workpiece, the compensation value of the third processing area is determined as follows:

[0106] K3=(Z3-Z7) / (Ymax-Ymin); β3=arctan(K3)

[0107] Then, according to the real-time processing direction and the compensation values ​​of the multiple processing areas, the situations where the groove angle compensation value of the grooved workpiece is determined include:

[0108] like Figure 6 As shown in the figure, when the processing direction is 0°<α≤22.5° or 337.5°<α≤360° or 157.5°<α≤202.5°, that is, the processing direction is in the A and E processing areas, and XL≥300mm or YL≥300mm, the groove angle compensation value is β3; when the processing direction is 22.5°<α≤67.5° or 202.5°<α≤247.5°, that is, the processing direction is in the B and F processing areas, and XL≥300mm or YL≥300mm, the groove angle compensation value is β3.
