Offline automatic programming of arc prototype system based on arc welding robot

At present, methods of graphic teaching for robot are mostly adopted in offline programming system to establish the path of robotic movement.However, for this programming of the approach complex path, the workload is still a large.Moreover, the robot procedure (JOB)is hardly formed by using the position data and welding instructions, which calculated directly by path planning.The offline automatic programming was researched for arc welding robots.The relative JOB is a data exchange interface ofMOTOMAN robots.With this interface, the offline automatic programming module generates robots procedures.Through ODBC interface, offline automatic programming module queries the planning instructions and data in the corresponding database in the arc prototype system. The advantages of database are conducive to the expansion of offline programming system.The experiment results show that the researched offline programming operates stably, and the robot moves coherently, and the welding path is accordant to the design.
