Study of the Statistical Models with Contact Parameters of Machine Tool Guideway Rough Surface

Abstract:

Friction and wear of the guideway is an important factor which affects its precision, the parameter which affects friction and wear performance is no single. Among them, surface precision of the guideway has a great influence on the wear. In this paper, Taylor Hobson roughness profilometer is used to measure the guideway specimen according to the principle of statistics, and then the surface topography assessment parameters are obtained. Based on those, the rough surface topography is characterized and statistical models with contact parameters are established. Contact models are analyzed by using simulation software Mat lathe results: the contact parameter values show linear growth trend as the distance decreasing, the values become smaller as the roughness increasing, but the trend increases corresponsive.
