For a Long Life of Natural Single Crystal Diamond Tool

The Investigation of Ultra Precision Cutting for Electroless Ni-P

Abstract

This research is primarily aimed at the longer tool life of natural single crystal diamond in ultra precision for an electroless nickel phosphorus plating. The following results have been obtained : (1) The profile to increase of the tool life drawn from this work is that back and side rake angle were formed at -5 with nose radius 0.76mm and other tool dimensions has constant values. (2) The groove wear of natural single diamond tool is grown by asperity of tool feed mark on the ultra precision machined surface. (3) The typical tool wear of diamond shows an attrition wear without a chipping failure in the optimum tool profile.
