Cutting Force Model for Diamond Cutting Microstructured Surfaces

Abstract

The depth of cut changed periodically along the contour of the cutting surfaces. The diamond tool of sharp point tip was used in diamond cutting microstructured surfaces with Fast Tool Serve (FTS). All reported the cutting force model were not suitable for accurately predicting cutting force. A cutting forces model concerned with edge radius, spring back and dynamic shear angle was proposed for diamond cutting microstructured surfaces. The model was verified with a series of experimental results. The results showed that the proposed model was able to exactly predict the cutting force.
