[0023] The method for realizing water jet cutting table avoidance control of the present invention comprises the following steps:

[0024] (1) Collect the areas that need to be avoided and generate an avoidance graphic set;

[0025] (2) Collect the graphics elements that need to be processed in the tool path and generate a processing graphics set;

[0026] (3) Calculate the optimal offset of the tool path.

[0027] As a preferred embodiment of the present invention, the step (3) specifically comprises the following steps:

[0028] (3.1) Determine the range of possible deviation;

[0029] (3.2) At each offset position, calculate the total intersection length of the processing graphics set in the avoidance graphics set;

[0030] (3.3) The offset position corresponding to the minimum total intersection length is taken as the optimal offset.

[0031] The device for realizing water jet cutting table avoidance control of the present invention comprises:

[0032] a processor configured to execute computer-executable instructions;

[0033] The memory stores one or more computer executable instructions. When the computer executable instructions are executed by the processor, the steps of the method for realizing water jet cutting table avoidance control are realized.

[0034] The processor for implementing water cutting table avoidance control of the present invention, wherein the processor is configured to execute computer executable instructions, and when the computer executable instructions are executed by the processor, the various steps of the above-mentioned method for implementing water cutting table avoidance control are implemented.

[0035] The computer-readable storage medium of the present invention stores a computer program thereon, and the computer program can be executed by a processor to implement the various steps of the above-mentioned method for achieving water jet cutting table avoidance control.

[0036] In a specific embodiment of the present invention, a better water jet cutting table avoidance method is provided to solve the defects brought by the area intersection method and achieve a better avoidance effect.

[0037] The total length of the intersection of the machining graphics set in the avoidance graphics set is used as the judgment condition for whether it is the best offset, rather than the total area of ​​the intersection.

[0038] The purpose of the present invention is to achieve a better table avoidance effect through the following measures:

[0039] (1) Collect the areas that need to be avoided and generate an avoidance graphic set;

[0040] (2) Collect the graphics elements that need to be processed in the tool path and generate a processing graphics set;

[0041] (3) Calculate the optimal offset of the tool path;

[0042] (3.1) Determine the range of possible deviation;

[0043] (3.2) At each offset position, calculate the total intersection length of the processing graphics set in the avoidance graphics set;

[0044] (3.3) The offset position corresponding to the minimum total intersection length is taken as the optimal offset.

[0045] The technical solution of the present invention does not compensate the graphics, but only calculates the distance that the graphics need to be offset, without changing the shape of the graphics. The technical solution of the present invention needs to calculate the cutting length of the intersection of the processing graphics and the avoidance area, and use this as the convergence judgment condition for the optimal offset.
