Effect of nominal diameter difference of threads due to Change in orbital radius of helical interpolation motion in high-speed cutting on thread mills.

Abstract

This study examined the effect of nominal diameter on the machining of female threads using a TiSiN-based coated thread mill by changing the orbital radius of the helical interpolation motion. The work material was S50C and the nominal diameters of the threads were M10 and M12. The cutting conditions were varied in terms of rotation speed and feed rate. A wireless holder capable of simultaneously measuring tool vibration and cutting temperature and a 3-component piezoelectric cutting power meter were used as measuring instruments, and the machining characteristics were analyzed.
