The Surface Roughness Modeling of End Milling on Orthogonal Turn-milling Process

Abstract

The surface roughness of workpiece in turn-milling has become the research emphasis in recent years as an important evaluating factor. Based on the theoretical analysis of the residual height in orthogonal turn-milling, a roughness prediction model is established. The influences of turning speed, milling speed, radius of workpiece and axial cutting depth are discussed. It can be concluded that the ratio of turning speed and milling speed, the difference between radius of workpiece and axial cutting depth are the direct factors which affect the surface roughness.
