Towards the prediction of surface roughness induced by the belt finishing process:influence of the workmaterial on the roughness reduction rate

摘要

The belt finishing process is of great interest for the automotive industry so as to obtain smooth surfaces,especially after hard tuning operations.It enables to reduce and homogenize the surface roughness.It also prevents any shifting of surface quality from tool wear in hard turning.Belt finishing induces its own surface topography which will be rather independent of the previous one.Its surface signature is correlated to the abrasive belt topography.However models able to predict the final roughness of a part are missing.This article proposes to investigate the roughness reduction during the transitory state of the belt finishing process.The study is performed for different workmaterials.The main objective being to propose a first simple approach to predict the final roughness as a function of the initial roughness,work material and time.
