Computer Virtual Technology Used in Nc Machine Tool Compensation

Abstract

This paper presents a comprehensive virtual simulation model for CNC systems. The Virtual CNC (VRCNC) has a modular architecture and the special function. It can show movement process and the result, it can also show the effect of different movement mode, the displacement, velocity and acceleration of the process, the rationality of interpolation method and the motion control method. Additional CNC modules can easily be prototyped and integrated to the VRCNC by the user. Various application examples are presented which include building of physical dynamic control model, the prediction of the displacement, velocity and acceleration of the process, and the process of secant instead of curve. It can show closed loop drive dynamics. Detailed experimental verification is presented for each algorithm.
