Integration of Cutting Robot with CAD/CAM System Based on STEP-NC

Abstract

In order to solve the problem of openness, intelligence and low integration in the current machining robot control system, STEP-NC standard is introduced into the field of robot machining, and defines the STEP-NC data model of industrial robots. The 6R industrial robots are used to build the machining platform and the connection between the machining robot and the CAD / CAM system and the integrated data stream structure are discussed. The key issues involved in the post processing of the machining robot are studied. Taking the 6R robot as an example, the robot prototype system is established, and the kinematics solution in the post-processing process is studied and deduced. The cutting and post-processing system platform of cutting robot was established and the sample art machining was completed. The experimental and simulation results show that the system can complete the machining process of the cutting robot and generate executable robot machining instructions.
