数控机床故障诊断中PLC的应用研究

Application of PLC to Fault Diagnosis of CNC Machine Tool

以编程逻辑控制器PLC在数控机床中的应用为切入点,采用实例与理论相结合的方法,有效地对数控机床的各种故障加以反映,快速发出报警信号,帮助维修人员对数控机床的故障进行准确定位,及时地维修和排除数控机床发生的故障,使数控机床恢复正常,为PLC程序有效诊断数控机床故障提供经验借鉴.

Based on the application of programmable logic controller PLC to the numerically-controlled machine tool,using the method of combination of theory and examples,this study effectively reflects the faults of CNC machine tools,quickly issues a warning signal,and helps to locate the faults,and timely puts the CNC machine tools back to normal,thereby offering experience reference for the effective fault diagno-sis of CNC machine tools for the PLC program.
