摘　　要：介绍了自动对刀仪。该对刀仪采用电触发式传感器,利用FANUC系统的宏程序编制对刀监测程序,刀具以一定速度向传感器接近,接触后瞬间发出系统信号,数控系统立即记录当前刀具坐标值,并自动修正刀具补偿值,完成对刀功能。根据自制对刀仪设计时的问题提出该设计的一些改进措施。This paper firstly introduces the self-made tool auto-checking instrument. By using the electric-based trigger sensor, the macro program of the FANUC system is utilized in the tool to compile the surveillance procedure. The tool approaches the sensor at a certain speed and sends out the systematic signals instantly after approaching, meanwhile, the NC system will immediately record the current tool coordinate value and automatically modify the tool compensation value to complete the function of the auto-checking instrument. Finally, this paper puts forward some improvement measures of this design based on some problems.
