Investigation of Cutting Phenomena in Screw Cutting by Three Axis Controlling Helical Interpolate Motion

Abstract

In the present report, we focus on the screw cutting phenomena by three axis controlling helical interpolate motion with a machining center. A thread mill tool is used to perform the screw cutting. We measured the cutting forces and the cutting torque in screw cutting, and proposed a novel method to derive the radial force component from the measured ones. As a result, it could be seen that the cutting forces at the rough and finishing tool edge were discussed from a view of machined accuracy.
