Development of Small Displacement Device of End-mill at Cutting Point using Electro-magnetic Force

Abstract

This paper presents that the small displacement device to be driven by electro-magnetic force compensates the quadrant glitches which is one of machining error caused by dynamic motion error of machine tool table. New small moving device is designed and made by way of trial and the device is installed to spindle head of machine tool. The proposed compensation method is verified through simulation and experiment.
