Abstract: A cutting platform is established by using a 6R industrial robot. The data flow for cutting robot to connect and integrate CAD/CAM system is studied. Some crucial problems encountered during the post-processing procedure are specially investigated. A prototype of cutting robot is established, on which some processing steps in the post-processing process are studied and discussed. The steps include transforming coordinate systems, solving kinematics, solving redundant degrees of freedom and avoiding singular points. A simulation and post-processing system platform is developed in order to perform the implementation of a cutting robot. Some 2D and 3D workpieces are cut by the cutting robot, which verifies the functionality and feasibility of the post-processor and the robot code generator inside the whole system.

Key words: CAD/CAM, Cutting robot, Post-processing
