Abstract
Frictional behaviour becomes main study in machining, especially for ball screw driven positioning stage. This paper presents friction behaviour analysis in pre-sliding regime using various mathematical models that produce a sigmoid like curve. In pre-sliding regime, friction behaviour is described while axes moving at relatively low velocity. Furthermore, a smooth continuous curve is needed in the transition between sliding regimes. Generalized Maxwell Slip (GMS) model is known model that well describes the friction behaviour at pre-sliding regime. Sigmoid like function is proposed as a significant parameter in modified GMS. The numerical simulation was performed to show the influences and effects for each sigmoid like curve. The result analysis leads to the development of an adaptive friction compensation model.
