数控机床伺服进给系统状态监测方案的分析比较

摘要

为了得到准确获取机床状态监测信号的方法，研究了机床状态信号获取的3种方案，即外置传感器信号、内置传感器信号和伺服驱动器监测端口信号。这3种信号都是可靠的信息来源，但是信号获取的难度和信号质量各有优劣。分析比较了这3种方案，分析结果对研究数控机床伺服进给系统在线监测技术、提高机床可靠性和加工质量具有参考意义。%In order to get methods of accurately obtaining machine tools condition monitoring signals,the three schemes of obtai-ning machine tools condition signals were researched,which included external setting sensor signals,internal setting sensor signals and servo drivers monitoring interface signals. The three signals were all reliable signal sources,however,the quality and difficulty level to obtain of signals were different. These three schemes were compared and analyzed. The analysis result has reference significance for re-searching the monitoring technology on-line of CNC machine tools servo feed system and improving reliability and machining quality of machine tools.
