数控机床是集机、电、液于一身的机电设备,具有技术密集和知识密集的特点。一旦发生故障,诊断的难度大。尤其是对机械部件的检测与诊断更为困难,误诊率较高。主要研究数控机床上滚动轴承的特点与故障检测。 CNC machine is a machine, electricity, liquid in a mechanical and electrical equipment, with technology-intensive and knowledge-intensive features. In the event of failure, diagnosis is difficult. Especially for the detection and diagnosis of mechanical parts more difficult, higher misdiagnosis rate. Mainly on NC machine tool rolling bearing characteristics and fault detection.
