All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The three axial directions are all on the Y coordinate system of the device, that is, the projections of the trajectories of the first cutting axis 1, the second cutting axis 2 and the measuring axis My in the axial directions are on the same plane, and the motion trajectories of the axes can be simplified to be straight lines on the same plane. Fig. 2 is a simplified schematic diagram of a motion trajectory. The axes may not be perfectly parallel, thus causing differences in coordinate representation of the axes. It should be noted that the number of the cutting axes is only illustrated schematically and is not limited specifically.
Therefore, for a cutting device with multiple cutting axes, fig. 3 is a flowchart of a coordinate compensation method provided in an embodiment of the present invention, which is applicable to a situation where the cutting device performs cutting coordinate compensation, and the method can be executed by a coordinate precision compensation device, which can be implemented in a hardware and/or software manner. The method specifically comprises the following steps:
s110, acquiring the track length between two coordinate points on the cutting axis based on the uncompensated coordinates of the cutting axis;
specifically, the uncompensated coordinates refer to coordinates determined with the cutting axis itself as an axis standard before being uncompensated. The trace length refers to the length between two coordinate points that cut the workpiece in the axial direction according to uncompensated coordinates along the cutting axis. Fig. 4 is a simplified schematic diagram of a motion trajectory on the first cutting axis and the measuring axis according to an embodiment of the present invention, and referring to fig. 4, a cut is performed on a workpiece according to a coordinate standard of the first cutting axis itself to obtain two cutting points, so that a trajectory length LenthY1 of the two coordinate points on the cutting axis can be determined according to the two cutting points.
S120, taking the measuring axis as a standard coordinate axis, and obtaining the standard length of the track on the relative measuring axis between the coordinate points of the cutting axis;
specifically, referring to fig. 4, taking the measuring axis as a standard coordinate axis, and the axial direction of the measuring axis is a horizontal direction, for example, the length of the motion track on the measuring axis corresponding to two cutting points may be measured by using the measuring device as the standard length lentitmy.
S130, determining the offset ratio of the cutting axis to the measuring axis according to the track length and the standard length;
wherein the offset ratio may characterize the offset angle of the first cutting axis from the measuring axis according to similar principles. For example, the offset ratio may be the ratio of the track length to the standard length, i.e., Δ C = LenthY1/LenthMy. For data accuracy, the corresponding track length may be as long as possible.
S140, acquiring the offset of the cutting axis coordinate relative to the measuring axis coordinate;
specifically, the offset is a difference between a coordinate determined by itself as an axis standard before the cutting axis is not compensated and a coordinate of a measurement axis as a standard coordinate axis, and in an exemplary manner, the offset obtaining process: fig. 5 is a simplified schematic diagram of the first cutting axis, the second cutting axis and the motion track on the measuring axis according to the embodiment of the present invention, referring to fig. 5, a target coordinate P0 is set with the measuring axis as a standard axis, the target coordinate P0 is sent to the first cutting axis and the second cutting axis, so that the first cutting axis and the second cutting axis respectively scribe on a workpiece according to their own standards, and respectively observing the position coordinates of the scratch corresponding to the first cutting axis and the scratch corresponding to the second cutting axis on the measuring axis through the measuring device, wherein the position coordinates are respectively counted as P1 and P2, and then P1-P0 and P2-P0 are the Offset Offset1 of the first cutting axis and the Offset Offset2 of the second cutting axis. The coordinate relation is thus compensated in the parallel state: the compensation coordinate PY1 of the first cutting axis = PMy + Offset1, and the compensation coordinate PY2 of the second cutting axis = PMy + Offset1. The compensation coordinate is only suitable for the condition that the cutting axis is parallel to the measuring axis, the mapping of the same position under the coordinate of the other axis is unchanged under the parallel condition, and if the cutting axis is not parallel to the measuring axis, the deviation ratio, namely the coordinate change caused by the included angle between the cutting axis and the measuring axis, needs to be considered.
And S150, determining the compensation coordinate of the cutting axis according to the offset ratio and the offset.
Specifically, in combination with the compensation coordinate relation in the parallel state, the product of the Offset amount Offset1 of the first cutting axis and the Offset ratio according to the similarity relation is the Offset amount when the first cutting axis and the measuring axis are not parallel in the axial direction. The product of the Offset amount Offset2 of the second cutting axis and the Offset ratio is an Offset amount in the case where the second cutting axis and the measuring axis are not parallel in the axial direction. The final coordinate compensation relationship is therefore: the compensated coordinates PY1 = PMy + Offset1 × Δ C of the first cutting axis, and the compensated coordinates PY2 = PMy + Offset2 × Δ C of the second cutting axis.
According to the technical scheme provided by the embodiment of the invention, the track length between two coordinate points on the cutting axis is obtained based on the uncompensated coordinates of the cutting axis; then taking the measuring axis as a standard coordinate axis, and obtaining the standard length of the track on the relative measuring axis between the coordinate points of the cutting axis; therefore, the angular offset between the cutting axis and the measuring axis is reflected according to the track length and the standard length, the offset of the cutting axis coordinate relative to the measuring axis coordinate is obtained, and the compensation coordinate of the cutting axis is determined according to the offset ratio and the offset. The measuring shaft is used as a standard shaft, and the angle deviation and the coordinate deviation of the plurality of cutting shafts relative to the measuring shaft are respectively recorded, so that the coordinates of the cutting shafts are subjected to coordinate compensation by utilizing the coordinates of the measuring shaft, the coordinate values with the same value can be reflected to the same point by the cutting shafts in a non-parallel state, the coordinate difference of each cutting shaft is reduced, the accurate movement in a system can be realized, the shaft error adjusting time is shortened, and the production efficiency is improved.
Optionally, determining the compensation coordinates of the cutting axis according to the offset ratio and the offset amount includes: the compensation coordinate of the cutting axis is the sum of the product of the offset and the offset ratio and the coordinate of the measuring axis.
Specifically, the offset is a difference between a coordinate determined by itself as an axis standard before the cutting axis is not compensated and a coordinate of a measurement axis as a standard coordinate axis, and in an exemplary manner, the offset obtaining process: fig. 5 is a simplified schematic diagram of the first cutting axis, the second cutting axis and the motion track on the measuring axis according to the embodiment of the present invention, referring to fig. 5, a target coordinate P0 is set with the measuring axis as a standard axis, the target coordinate P0 is sent to the first cutting axis and the second cutting axis, so that the first cutting axis and the second cutting axis respectively scribe on a workpiece according to their own standards, and respectively observing the position coordinates of the scratch corresponding to the first cutting axis and the scratch corresponding to the second cutting axis on the measuring axis through the measuring device, wherein the position coordinates are respectively counted as P1 and P2, and then P1-P0 and P2-P0 are the Offset Offset1 of the first cutting axis and the Offset Offset2 of the second cutting axis. The coordinate relation is thus compensated in the parallel state: the compensation coordinate PY1 of the first cutting axis = PMy + Offset1, and the compensation coordinate PY2 of the second cutting axis = PMy + Offset1. The compensation coordinate is only suitable for the condition that the cutting axis is parallel to the measuring axis, the mapping of the same position under the coordinate of the other axis is unchanged under the parallel condition, and if the cutting axis is not parallel to the measuring axis, the deviation ratio, namely the coordinate change caused by the included angle between the cutting axis and the measuring axis, needs to be considered.
And combining the compensation coordinate relation in the parallel state according to the similarity relation, wherein the coordinate compensation relation is as follows: the compensated coordinates PY1 = PMy + Offset1 × Δ C of the first cutting axis, and the compensated coordinates PY2 = PMy + Offset2 × Δ C of the second cutting axis.
Optionally, the cutting device comprises a cutting device and a measuring device; the cutting device moves on the cutting shaft along the axial direction; the measuring device moves on the measuring shaft along the axial direction; fig. 6 is a schematic flow chart of a method for obtaining a track length according to an embodiment of the present invention, and referring to fig. 6, the method includes:
s210, based on the uncompensated coordinates of the cutting shaft, cutting the workpiece at two different positions by the cutting device;
specifically, the uncompensated coordinates refer to coordinates determined with the cutting axis itself as an axis standard before being uncompensated. The cutting device cuts at two different positions on the workpiece according to the uncompensated coordinates, and the coordinates of the two scratch positions can be reflected on the motion track of the cutting shaft as the cutting device moves along the axial direction of the cutting shaft.
S220, obtaining the track length between two coordinate points on the corresponding cutting axis of the two cutting positions on the workpiece.
Specifically, the length of the track between two coordinate points on the cutting axis of two cutting positions on the workpiece is measured.
Optionally, determining the offset ratio of the cutting axis to the measuring axis according to the track length and the standard length includes:
the offset ratio is the ratio of the track length to the standard length.
Specifically, when the cutting axis and the measuring axis are not parallel, only the angle between the cutting axis and the measuring axis needs to be determined, but actually, the measurement implementation difficulty is high, so that the offset ratio of the cutting axis and the measuring axis can be represented by using the actual length of the distance with the same length on each axis as a reference.
Fig. 7 is a schematic flowchart of a method for obtaining an offset of a cutting axis coordinate relative to a measuring axis coordinate according to an embodiment of the present invention, and referring to fig. 7 in conjunction with fig. 5, the method includes:
s310, setting a target coordinate by taking the measuring axis as a standard coordinate axis;
in which the coordinate information of the measuring axis is related to the position observed by the measuring device, so that the coordinates of the measuring axis are the same as the coordinate system of the measuring device and different from the coordinate system of the cutting axis, and thus it is necessary to relate the coordinate systems of the measuring axis and the cutting axis. The target coordinate P0 is a coordinate parameter set with the measurement axis as a standard coordinate axis.
S320, cutting the workpiece by the cutting device according to the target coordinates;
specifically, the cutting device cuts the workpiece with target parameters according to the cutting shaft standard.
S330, measuring the measurement coordinate of the cutting position of the workpiece relative to the measurement axis by the measuring device;
specifically, the measuring device is used for respectively observing the measuring coordinates of the scratch position corresponding to the first cutting axis and the scratch position corresponding to the second cutting axis on the measuring axis, and the measuring coordinates are respectively counted as P1 and P2.
And S340, determining the offset of the cutting axis coordinate relative to the measuring axis coordinate according to the measuring coordinate and the target coordinate.
Illustratively, the Offset amount is the value obtained by subtracting the target coordinate from the cutting coordinate, and P1-P0, and P2-P0 are the Offset amount Offset1 of the first cutting axis and the Offset amount Offset2 of the second cutting axis. Compensating the coordinate relation in the parallel state: the compensation coordinate PY1 of the first cutting axis = PMy + Offset1, and the compensation coordinate PY2 of the second cutting axis = PMy + Offset1. The compensation coordinate is only suitable for the condition that the cutting axis is parallel to the measuring axis, the mapping of the same position under the coordinate of the other axis is unchanged under the parallel condition, and if the cutting axis is not parallel to the measuring axis, the deviation ratio, namely the coordinate change caused by the included angle between the cutting axis and the measuring axis, needs to be considered.
Fig. 8 is a schematic structural diagram of a coordinate precision compensation device according to an embodiment of the present invention, and referring to fig. 8, the coordinate precision compensation device is applied to a cutting apparatus, the cutting apparatus includes a measuring axis and at least two cutting axes; wherein, the projection of cutting axis and measuring axis orbit on the axial is in the coplanar, and coordinate precision compensation arrangement includes:
a first obtaining module 810, configured to obtain a length of a trajectory between two coordinate points on a cutting axis based on an uncompensated coordinate of the cutting axis;

a third obtaining module 840, configured to obtain an offset of the cutting axis coordinate relative to the measurement axis coordinate;
and a second determining module 850 for determining the compensated coordinates of the cutting axis according to the offset ratio and the offset amount.
Specifically, the first obtaining module 810 performs cutting on the workpiece according to the coordinate standard of the first cutting axis itself to obtain two cutting points, so that the trajectory length LenthY1 of the two coordinate points on the cutting axis can be determined according to the two cutting points. The second obtaining module 820 takes the measuring axis as a standard coordinate axis, and measures the length of the motion track on the measuring axis corresponding to the two cutting points by using the measuring device, as a standard length LenthMy. The first determination module 830 makes a ratio of the track length to the standard length, i.e., Δ C = LenthY1/LenthMy. The third obtaining module 840 sets a target coordinate P0 with the measuring axis as a standard axis, sends the target coordinate P0 to the first cutting axis and the second cutting axis, so that the first cutting axis and the second cutting axis are respectively scribed on the workpiece according to their own standards, and then respectively observes the scribe line position coordinates corresponding to the first cutting axis and the scribe line position coordinates corresponding to the second cutting axis on the measuring axis through the measuring device, and respectively counts as P1 and P2, and then P1-P0, and P2-P0 are the Offset1 of the first cutting axis and the Offset2 of the second cutting axis. The coordinate relation is thus compensated in the parallel state: the compensation coordinate PY1 of the first cutting axis = PMy + Offset1, and the compensation coordinate PY2 of the second cutting axis = PMy + Offset1. The second determining module 850 obtains the final coordinate compensation relationship according to the similarity relationship by combining the compensation coordinate relationship under the parallel state, wherein the final coordinate compensation relationship is as follows: the compensation coordinate PY1 = PMy + Offset1 × Δ C of the first cutting axis, and the compensation coordinate PY2 = PMy + Offset2 × Δ C of the second cutting axis.
