Numerical Painting Application and Control for NC Painting Robot.

Abstract

Ultimate goal of this study is making up CIM of painting process for large scale steel product. For the purpose of it, the study aims at obtaining numerical conditions of painting application and applying them to the control of robot. First, we made it clear that spray distance, painting velocity and orientation of spray gun are basic conditions of painting application for robot. Then we have developed the method of simulation of numerical relationship between application condition and film thickness through experimental equation. This method is essential for generating operation data for robot in the offline programming system. We have also developed the new control method for dynamic painting application. That is the active control of film thickness change at the start and end section of painting path, which means that painting robot have obtained the skill of painting belonging to painting worker.
