Abstract

In this study, the authors investigate improving the precision of a thread by deriving its radial force (thrust force) with a four-component piezoelectric dynamometer and thread cutting by helical interpolation motion using a thread mill. The accuracy of the thread is discussed with respect to changing hardness of the work material. In addition, by recording the position information at the time of thread cutting from the servo guide on the data logger, the relationships among the cutting forces of the four components and the radial force are confirmed by various methods; further, the consistency of these relationships was confirmed.
