Study on key technologies of numerical control turning simulation based on STEP-NC

This paper presents a simulation system of intelligent STEP-NC Turning controller. Architecture of the STEP-NC turning simulation system was presented. Some key technologies to implement the simulation system including cutting force modeling, vibration modeling and surface roughness modeling were described in detail. Furthermore, graphic user interface (GUI) was developed to input the simulation parameters and output the simulation results. Simulating with the developed simulation models, some important conclusions were obtained. As a result, the numerical control simulation system based on STEP-NC provides a critical module to aid STEP-NC controller intelligently controlling the turning machining process.
