Study on Surface Roughness of Inclined Surface Machining using Radius End Mill

Geometrical Analysis of Theoretical Roughness and Experiments with Scanning

Abstract

Recently, radius end mills have been developed to machine highly accurate and efficient three-dimensional shapes. But the cutting edge shape of the cutters is complex and there are few papers that focus on the radius end mill. Therefore, in this paper we geometrically analyze the theoretical roughness for inclined surface with the scanning method. At first, the equation for theoretical roughness is shown. Secondly, the surface roughness is measured by cutting tests and compared with the experimental results. Finally, it is shown that the estimated values of the theoretical roughness are almost coincident to the experimental values and analytical method for calculating the theoretical roughness is highly accurate.
