Machine tool motion dynamic graphic simulation system using service filed bus to communicate

Abstract

The invention discloses a construction method of a machine tool motion dynamic graphic simulation system and the machine tool motion dynamic graphic simulation system established on the method. The simulation system comprises a numerical control system, a servo device, a field bus, a bus data receiver, a simulation PC (Personal Computer) and a CAD (Computer Aided Design) modeling system. A machine tool layout structure and part modeling data which are provided by the CAD system are used by the PC; when the numerical control operates, a data frame is transmitted by the servo field bus during each cycle; a position instruction data frame is received by the simulation system through the bus data receiver and is transmitted to a simulation computer through Ethernet; and the simulation system can be used for generating three-dimensional virtual motion of a machine tool part according to the machine tool modeling data and each servo position. By adopting the construction method of the machine tool motion dynamic graphic simulation system, a software structure of the numerical control system is simplified and the simulation and operation time of the numerical control system is reduced; and a general numerical control machine tool motion simulation system is formed without occupying a system operation display interface, and thus development expense of software is reduced.
