摘　　要：自动换刀模块是数控加工设备中的重要部分。设计一种圆盘式刀库的换刀控制系统,以西门子S7-200系列的PLC为控制器,步进驱动器设定脉冲电流值和细分数,驱动步进电机带动刀具盘旋转确定角度实现自动换刀功能。侧重步进电机的驱动参数在软件STEP7 MicroWin中的两种设置方法。Automatic Tool changing module is an important part of NC machining equipment.In this paper,a tool changing control system of disc Cutter storehouse is designed.The Siemens S7-200 PLC is used as the controller,the driver is used to setup the pulse current value and the subdivision number,and the driving step motor drives the cutter disc to rotate to the angle to realize the function of automatic tool changing.This paper focuses on three methods of setting up step motor parameters in STEP7.
