开放式数控磨削加工系统中直线电机的应用研究

对高速、超精密加工来说，传统的进给系统已难以满足要求。近年来，直线电机作为一种新型直接驱动进给装置得到广泛应用。简单介绍了直线电机的基本原理，并利用开放式控制器PMAC(Programmable Muhi—Axis Controller)集成了一套磨削加工系统，在利用PID 前馈控制法对直线电机控制性能研究的基础上，实现了直线电机的微量往复进给运动，为推动直线电机及PMAC在高速高精度数控机床中的应用打下了基础。

Application Research of Linear Motor on Open CNC Grinding Manufacture System

To the manufacture of high-speed and super- precision, the conventional feed system hasn't satisfied the requirements . Recently, as a new-style feed equipment drived directly, linear motor is being applied widely. In this paper, the basal principle of linear motor is introduced simply and the NC grinding machine is integrated with PMAC(Programmable Multi-Axis Controller).On the base of the control performance research of Linear Motor with PID plus forward feed control algorithm ,reciprocating movement has been accomplished.The results of research promote the application of linear motor and PMAC in the high-speed and super-precise NC machine tools.
