Problems solved by technology

After cutting the contour in laser processing, the part may turn upside down, causing the risk of head collision when cutting the part with which it is co-edged
The traditional co-edge cutting either manually removes the lifted parts by the operator; or solves this problem by adding micro-joints to the outer contour of the parts to prevent the parts from warping. Manual operations cause frequent pauses in the processing process and affect production efficiency; adding micro-joints will give Processing brings additional piercing actions, which affects the quality of the cut section of the outer contour of the part and wastes cutting time

Embodiment Construction

[0022] The present invention will be further described in conjunction with the accompanying drawings.

[0023] see figure 1 , first perform one-dimensional coedge on the regular rectangle, and set the size of the gap, then sort the coedge parts and confirm the processing order of the parts.

[0024] When generating the toolpath, search for parts according to the order of the parts. After judging that the part is not the last one to be processed, find the end point of the common side line between the part and the next part. Through the end point and gap parameters, find the processing start and end point of the part contour, and confirm Cutting direction; if it is judged that the part is the last one to be processed, it is only necessary to ensure that the starting point of the part is not on the common edge line, and the entire tool path generation process can be completed.

[0025] Such as figure 2 As shown, the black rectangle is a schematic diagram of the coedge parts to...

Abstract

The invention relates to the technical field of laser cutting, in particular to a method for generating a one-dimensional common-edge C-type cutting tool path. Only when an (n+1) part is cut, canan n part is completely separated from a board, meanwhile, due to an existing gap, the n part is separated by breaking off the gap through the self-weight, and the separation time is enough for a laser cutting machine to completely go through the contour of the n part. The problem of a collision deviation due to part upwarping in the common-edge cutting process is completely avoided, meanwhile, the method is safe and reliable, and the whole cutting process does not need manual intervention.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to a method for generating a one-dimensional coedge C-shaped cutting tool path. Background technique [0002] In the laser cutting process, one-dimensional coedge cutting of regular rectangles is widely used as a method to improve cutting efficiency and material utilization rate. The one-dimensional coedge C-type tool path is to generate a special processing path for one-dimensional array coedge a solution for . After cutting the contour in laser processing, the part may turn upside down, causing a risk of head collision when cutting the part with which it is co-edged. The traditional co-edge cutting either manually removes the lifted parts by the operator; or solves this problem by adding micro-joints to the outer contour of the parts to prevent the parts from warping. Manual operations cause frequent pauses in the processing process and affect production efficiency; adding ...
