Abstract

This study deals with a new method of the compliance measurement in cutting process on a CNC lathe. In general, the impact test is widely used to measure frequency response functions (FRF). However, this test cannot be adopted during cutting process in terms of danger and accuracy of measurement. Therefore, a new method of the FRF measurement that the turning process itself becomes frequency-sweep excitation is proposed. In this paper, our method is explained first, and a comparison experiments between results of the conventional impact test and our proposed method is described. As the result, it was confirmed that the measured natural frequencies was slightly different between these tests.
