Embodiment Construction

[0035] In order to facilitate the understanding of the present invention, the method and cutting system for laser cutting corners of workpieces will be described more fully below with reference to related drawings. The preferred embodiment of the method for laser cutting workpiece corners and the cutting system is given in the accompanying drawings. However, the method and the cutting system for laser cutting workpiece corners can be implemented in many different forms, and are not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the method and cutting system for laser cutting workpiece corners more thorough and comprehensive.

[0036]It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be dir...

Abstract

The invention relates to a method and cutting system for laser cutting workpiece turning. The method for cutting the corner of the workpiece by the laser includes: providing a workpiece; controlling the laser beam to adopt first curve cutting model to control the laser beam to cut the workpiece from the first edge to the start point of the corner position, controlling a laser beam to cut a predetermined length from the corner position of the workpiece using a second curved cutting mode of a control curve; controlling the laser beam to cut from the end point of the corner position to the secondedge of the workpiece by using the third curve cutting mode of the control curve; controlling the laser beam to cut along the second edge of the workpiece by using the fourth curve cutting mode of the control curve; the method for cutting the corner of the workpiece according to the laser beam is adapted to be processed at different positions of the workpiece processed by the laser beam, so thatthe problem that airflow turbulence occurs at the corner position of the workpiece and is not easy to be eliminated is avoided, and the cutting of the plate is continuously carried out.

Description

technical field [0001] The invention relates to the technical field of fiber laser cutting, in particular to a method and a cutting system for laser cutting workpiece corners. Background technique [0002] Laser cutting is to irradiate the workpiece with a focused high-power-density laser beam, so that the material of the irradiated workpiece is rapidly melted or vaporized or ablated or reaches the ignition point, and at the same time, the molten material is blown away by the high-speed airflow coaxial with the laser beam. In this way, the workpiece can be cut. However, when the laser beam cuts at the corner position of the workpiece, especially when the corner angle is too small and the thickness of the workpiece is thick, there will be problems of turbulent air flow and difficult removal of the melt at the corner position of the workpiece, resulting in the cutting of the plate. Difficulty, so that the cutting of the plate cannot continue. [0003] Such as figure 1 As sh...
