Abstract

This research deals with the estimation of cutting forces by using motor currents in a drive system on a machine tool. Since motor currents are greatly influenced by the friction imposed on a drive system, a model of the friction forces is needed to estimate cutting forces. In this paper, we propose a friction model that considers influences of the feedrate and the table position on the friction for two different machine tools. One of those has a ball screw and linear guides for its drive systems. The other has a linear motor and hydro static guideways. The estimation accuracy of cutting forces are evaluated experimentally with the present friction model.
