Method of machining regular holes with laser cutting robot arm

Abstract

A method for processing regular holes using a laser cutting robot arm, comprising: controlling the end of the laser cutting robot arm to move to the center point of the rule hole to be processed through a teaching pendant, and recording the coordinates of the center point through a robot arm controller ; The robot arm controller calculates the coordinates of multiple key points on the contour of the regular hole to be processed according to the coordinates of the center point and the preset geometric parameters of the regular hole; the robot arm controller first controls the laser cutting robot arm The end moves from the center point to one of the key points, and after the laser cutter is turned on, the end of the laser cutting robot arm is controlled to move to each of the remaining key points in order to form a closed path and return to one of the key points point. The teaching process of the invention is simple, and the processing precision is high.

Description

technical field [0001] The invention relates to a method of laser cutting and opening using a robot arm. Background technique [0002] With the needs of the production industry, the requirements for industrial robots in the laser processing industry have risen from simple planar manipulators to multi-degree-of-freedom manipulators. At present, six-axis manipulators are more commonly used. The rapid development of robotic arm technology has made it more and more widely used in the field of laser cutting technology. The six degrees of freedom of the six-axis robotic arm mean that the end of the robotic arm can translate along the xyz axis of the coordinate system and rotate around the xyz axis. Compared with traditional planar laser cutting equipment, the six-axis robotic arm can satisfy machine substitution to a greater extent. demand. [0003] In the implementation process of the six-axis robotic arm applied to laser cutting and opening, there are problems such as many gra...
