Off-Line Programming Design of Robots Based on DXF Files

To solve the problems of low efficiency and inaccurate positions of artificial trial teaching with industrial robots, a path method is developed to precisely control the robots. Based on a study of general and specific DXF file formats and developed in C # programming language, this method proposes a file format converting algorithm to extract the primitive information and optimize the primitives. The set of points optimized will then be transmitted to the robots through Ethernet and conduct the space coordinates calibration to finally generate robot path codes. Simulations and welding experiments prove that the method will greatly reduce the artificial trial teaching time, improve the working efficiency of robots, and it is adapted to the robots welding, cutting, coating and other trajectory path problems,etc..
