Utilizing TiC Cermet in Face-Milling

抄録

A higher production rate of face-milling will be realized if a more abrasion resistant but less tough tool material can be used without breakage. For this purpose, titanium carbide cermet tool material is studied for utilization in steel face-milling. The main problem is to provide the effective land and the proper rake angle to the cutting edge. The land strengthens the cutting edge against the impact, while the proper positive radial rake recovers the sharpness which is lost by the land. Basic studies with single bladed cutters presented enough knowledge for the design of a TiC cermet cutter. According to the basic data, a multi-bladed TiC cermet throw-away cutter was designed and examined in an experimental run. The trial multi-bladed cutter proved a good utility of TiC cermet in steel face-milling.
