Experimental analysis of friction behaviour for different linear guideways

Abstract

<p>The feed drive system for machine tool consists of rolling elements such as ball screw and linear guideways. It is well known that in the positioning of linear guideways using steel ball rolling, the contact surface has nonlinear spring characteristics. This phenomenon is deteriorating the accuracy of the machine tool. In this study, we have manufactured a feed drive system in which the physical contacts are only linear guides by using a linear motor as actuator. At first, we measured the responses to some fine feed amount for feed drive system. Next, the same experiment was performed by changing the linear guideways. This paper presents the transition of nonlinear spring characteristic region by considering the response to guideways.</p>
