摘　　要：通过对刀建立数控机床的工件坐标系是数控加工的重要内容,正确的对刀操作是数控加工精度的重要保证,也是实现数控机床高效率的基本要求。通过对对刀原理及机床坐标系的研究,针对FANUC-0i数控系统,对G50对刀、G54对刀和T指令对刀等多种不同的方法进行了较为深刻的分析,揭示了每种对刀方法与编程的联系。结合实例,对于合理设置刀具补偿参数,提高数控加工精度的方法进行了探讨。It is an important part of NC processing to set up the workpiece coordinate system by CNC machine toolsetting. The correct operation of the toolsetting is an important guarantee to the accuracy of CNC machining, and the basic requirements of high efficiency. Through the research of tool setting principle and the machine coordinate system, different methods have been carried out a more in-depth analysis, such as tool setting G50, G54 and T instructions for FANUC-0i CNC system.Each of the methods and programming link is revealed. With examples, the method are discussed for reasonable compensation parameters setting tool to improve the machining accuracy.
