Teaching device and teaching method for laser machining

Abstract

Provided is a teaching device whereby it is possible to avoid twisting a fiber connected to a galvano scanner beyond an allowable range. A teaching device for teaching a robot in a laser machining system, wherein the teaching device includes a path determination unit for determining a motion path for a robot on the basis the positions of a plurality of machining points set on an object; a simulation execution unit for executing a robot motion simulation in accordance with the determined motion path; a torsion amount evaluation unit for ascertaining the amount of torsion of an optical fiber by simulating the behavior of the optical fiber in accordance with the movement of the robot according to the motion simulation, and evaluating the torsion amount by comparing the torsion amount and a prescribed allowable range; and a robot orientation changing unit for changing the orientation of the robot so as to reduce the torsion amount for motion of the robot in which the torsion amount exceeds the prescribed allowable range.
