概要:
In turning of platinum alloy Pt850, the wear behavior of tools and the cutting characteristics of Pt850 are investigated experimentally. K10 carbide, cermet, ceramics and PCD are used as tool materials. K10 carbide and cermet are not suitable for the cutting of this material because severe wear on the tool flank was observed after a few second of cutting, that is, the width of the flank wear land was about 1 mm after 10 seconds cutting. The width of wear land of Al2O3 and Si3N4 ceramic tools was small compared with K10 carbide tool, but the cutting forces increased rapidly as the cutting proceed. PCD tool can be used for cutting of Pt850 because the width of flank wear land is much small compared with other tool materials used in this experiment and the increasing rate of cutting force is not so great. The influence of cutting speed on the flank wear of PCD tool is small. The surface roughness of work material Pt850 becomes lower when the smaller feed rate is chosen as a cutting condition and the cutting tool of larger radius corner is used. 続きを見る
