Research on the off-line programming system of six degree of freedom robot in vehicle door welding based on UG

Abstract

In this research, a 3D visual off-line programming system of six degree of freedom robot is developed based on the secondary development function of the 3D software UG. A new structure of off-line programming system for welding of six degree of freedom robot is built according to the characteristics of vehicle door welding. In this paper, C++ as the programming language and functions and development tools provided by UG/OPEN are applied to create a system of equipment modeling, motion simulation, path planning, off-line programming, state monitoring and other functional modules. In this research, the welding objects and six degrees of freedom robot were modeled respectively, genetic algorithm is used to realize the path planning of vehicle door welding, and a new system is applied to simulate the welding of the door, which proves to be effective. The system is able to meet the off-line programming requirements for the six degree of freedom robot in vehicle door welding process.
