Study on Skiving Process : Surface Accuracy

Abstract

The surface properties of workpieces obtained by skiving process (off-center turning) have been investigated experimentally for the effect of cutting conditions. The fidelity of transcription of cutting edge profile to skived surface and the methods to improve the surface accuracy are discussed. It was found that the surface roughness profile appeared having a plateau shape with small value of centerline depth Rp and that the surface roughness could be reduced by using the skiving tool with a small negative clearance angle or a certain edge roundness. The latter result can be explained in terms of the stronger burnish action. It is concluded that, from the viewpoint of the fidelity of transcription by power spectra, cemented carbide and cermet tools are superior to high speed steel tool.
