设计了刀具磨损检测控制系统,采用EPF10K10TC144-4主控芯片、位移传感器,采用分布式算法编制了控制软件并进行了系统仿真.将数据输入到CNC系统,修改刀具参数,并在数控车床上进行了切削实验.对比研究结果表明,该系统避免了人工检测误差、机床频繁停机,减少了换刀次数和重新对刀引入的二次误差,延长了刀具有效使用时间,且加工效率、加工精度、产品合格率都有明显提高.%The test and control system was designed on tools wear, it selected EPF10K10TC144-4 type controlling chip, displacement sensor, the control software was programmed using distributed algorithm, and system simulation was carried out. The data was input into the CNC system, tools parameters were modified. The cutting experiment was carried out in turning machine. The results of comparing study indicate that the manual examination errors and machine tools on-and-off frequently are avoided, the quadric errors introduced by the number of change tools and re-adjust tools are reduced, the effective time of using the tools was extended, in addition , machining efficiency, machining precision and product qualification rate have been obviously improved.
