Automatic Robot Trajectory for Thermal‐Sprayed Complex Surfaces

Abstract

Automatic trajectory generation for thermal spray application is highly desirable for today’s automotive manufacturing. Automatic robot trajectory for free‐form surfaces to satisfy the coating uniform is still highly challenging due to the complex geometry of free‐form surfaces. The purpose of this study is to present and implement a method for automatic generation of robot trajectory according to the given spray parameters on polygon profile and complex curved free‐form surfaces, such as torch speed, spray distance, spray angle, and so on. This software development foundation is an Add‐In programme of RobotStudio, which is off‐line programming and simulation software of ABB Company. The experimental results show that the robot trajectory can be generated rapidly, accurately, and automatically on the complex geometries by this method.
