Signal Sources

Obtaining the condition monitoring signals by rule and line is the base of distinguishing accurately the machine tool condition. In the paper, the three schemes of obtaining machine tool condition signals are researched, which are build-in sensor, external sensor and servo drivers monitoring interface. The three schemes are all reliable signal sources, however, the quality and difficulty level to obtaining of signals are different. In the paper, the three schemes are compared and analyzed. It is important for researching the condition monitoring technology of CNC machine tool servo system and improving machine tools reliability and machining quality.
