Influence of kinematics on the surface integrity in orthogonal turn-milling of aluminium matrix composites

This paper deals with the investigation of orthogonal turn-milling of aluminium matrix composites using CVD (chemical vapour deposition) diamond tipped end mills. The influence of eccentricity, tool position and milling strategy on the surface integrity is described. The results show that the lowest roughness values can be achieved by positioning the tool below the work piece axis, using an eccentricity e = 2.5 mm and choosing up milling.
