Method and device for avoiding corner overburning slag adhering defect based on sharp corner technology and arc technology, processor and storage medium thereof

Abstract

The invention relates to a method for avoiding a corner overburning slag adhering defect based on a sharp corner process and an arc process in a numerical control system. The method comprises the following steps of: drawing a cutting graph, and generating a tool path; calculating a sharp corner angle of each inflection point, and inserting an instruction of a sharp corner process; calculating the radius length of each section of arc, and inserting an instruction of an arc process; controlling a laser cutting head to move according to a cutting movement track, and starting cutting; starting the sharp corner process, and emitting light according to the sharp corner process when the sharp corner angle of the corner and the distance before the corner meet conditions; and starting the arc process, and when the arc radius and the arc starting point position meet conditions, emitting light according to the arc process. By the adoption of the method and device for avoiding the corner overburning slag adhering defect based on the sharp corner technology and the arc technology in the numerical control system, the processor and the computer readable storage medium of the processor, the situation that the laser power is too high due to movement deceleration is avoided, the problem that the corner position is prone to overburning slag adhering is solved, the cutting effect of the corner is improved, and the cutting quality requirement is met.

Description

technical field [0001] The present invention relates to the field of laser cutting, in particular to the field of high-power laser cutting, and specifically refers to a method, device, processor and computer-based computer control system for avoiding corner overburning and dross defects based on sharp corner technology and arc technology. Read storage media. Background technique [0002] Laser cutting technology is to control the laser generated by the laser cutting head to move along a certain direction, so as to realize the cutting of the plate and produce the required parts. [0003] In the existing related technologies, when cutting corners such as acute angles or small arcs, the setting requirements for the moving speed of the cutting head and the laser power are very precise, which easily affects the processing quality of the workpiece. Due to the special position of the corner, deceleration processing is required in motion control. When the laser power is too high, i...

Problems solved by technology

[0003] In the existing related technologies, when cutting corners such as acute angles or small arcs, the setting requirements for the moving speed of the cutting head and the laser power are very precise, which easily affects the processing quality of the workpiece.

Due to the special position of the corner, deceleration processing is required in motion control. When the laser power is too high, it is easy to cause over-burning and slag at the corner, resulting in the workpiece not meeting the quality requirements. The phenomenon of impermeability, the scrap rate of cutting workpieces is extremely high
