TEACHING DATA GENERATION METHOD FOR INDUSTRIAL ROBOT, TEACHING DATA GENERATION DEVICE FOR INDUSTRIAL ROBOT AND INDUSTRIAL ROBOT SYSTEM

摘要

PROBLEM TO BE SOLVED: To precisely polish the surfaces of plural curve surfaces by generating temporary tracks on virtual planes generated on the plural curve surfaces, projecting the virtual tracks on the plural curve surfaces and generating a real track, generating teaching data and the program of a robot based on the real track. SOLUTION: A CAM device generates polishing tracks for polishing the respective curve surfaces 41-44 based on inputted CAD data. The CAM device generates teaching point data and the program of the polishing robot. Namely, the CAD device generates the temporary polishing track on the generated virtual plane 49. At that time, the CAM device projects a start track, an end track and a point on an external line on the temporary plane 49 in accordance with an area where the curve surfaces 41-44 are ground. The start track and the end track equally divide opposite points and generate the virtual polishing track. Then, the temporary polishing track is projected on the respective curve surfaces 41-44 and generates the real polishing track.
