Abstract

Slideway is often employed in machine tools for heavy loading. As the rail is associated with the feeding system that required low friction, it is needed to scrap the contact surface in order to improving the lubrication condition and to lower the sliding friction. However, the scraping skill has been passing from mentor manually in the past, thus makes the scraping quality differs and difficult to effectively control the performance of the feeding system. This study develops a systematic approach to investigate the friction characteristics of scraping geometries in particular focuses on the tribological mechanism of wedged texture, in micron level, on the surface through theoretical analysis and numerical simulation. It explores the influences of the geometry configurations on the friction characteristics. The results show that the sliding block with micron level wedged texture can lower the sliding friction while makes itself moving upward. These effects lead to that the reduction of friction with time and finally approaches a steady state.
