A Study on the Calibration of Z-axis Depth of Cut using AE Signal in Micro-machining

마이크로 가공에서 AE 신호를 이용한 z 축 절삭깊이 보정에 관한 연구

There are technical requirements to manufacture large size functional parts with not only simple geometries like a flat or spherical surface but also sculptured geometries. In addition, the required machining accuracy for these parts is becoming more severe day-by-day. In general, the forms of machined parts are determined by relative position between the workpiece and the tool during cutting. To improve machining accuracy, the relative position error should be maintained within the required accuracy. This study deals with estimation and calibration of depth of cut using AE signal in micro-machining.
