Development of CNC System for Machining of Grooves in Automobile Synchronization Regulators Sleeve

摘要

On the basis of analyzing the shortcomings of the current technics for grooves machining, this paper deals with the development of Numerical Control System for machining of grooves in automobile synchronization regulator sleeve, which holds first-rate technics. In order to improve efficiency and precision of grooves machining and reduce cost of the cutter, Hypocycloid-based technique together with interpolation is introduced and studied. With IPC as system platform and PMAC (Programmable Multiple-Axes Controller) as the controlling center of the system, the open architecture of "PC-Based" is used in the CNC system and the framework of the CNC hardware is developed. According to the ideas of modularization and real-time multi-task scheduler, the CNC software system is carved into many modules and the framework of the CNC software is developed.
