Abstract

Surface topography is a significant factor that affects directly the surface integrity. There are several influencing factors. The purpose of the study is to investigate the effects of edge radius on surface integrity of Ti6Al4V. The proposed approach uses three different angles to study the relationship between the edge radius and surface roughness. The study develops theoretical model, roughness model based on cutting force and roughness empirical model. Experimental results show that machined surface integrity of TC4 is sensitive to the variations of the edge radius. The method is effective and can provide a guidance to optimize edge radius. It has realized higher accurate prediction of surface integrality in precision high speed milling with one of the models and has improved surface roughness quality of the work-piece.
