Abstract:By taking the 6R industrial robot as a numerical control processing platform, difficult points arising in the post processing of 5 axes cutter location file are studied. By taking cutter location files generated in Pro/E software as examples, integrated with unique structure of an industrial robot, expressing the coordinate system transformation, removing redundant degree of freedom (DOF), and deduced the relationship between each joint angle and the cutter location data, kinematics solution in post processing was realized, in order to develop a special purpose post processor of industrial robots in NC machining. Finally develop a post processor and realize data processing with VC60++.
