Abstract

Metal matrix composites (MMCs) have been found to possess tremendous prospective engineering applications that require materials offering a combination of lightweight with considerably enhanced mechanical and physical properties. However, the applications of MMCs are limited by their poor machinability which is a result of their highly abrasive nature that causes excessive wear to the cutting tools. Steam generator and steam feeding system was developed to generate and feed steam and is designed in such a way to control the cutting temperatures on the tool by circulating steam at different directions on chip tool interface.This arrangement maintains the tool's hot-strength at its desirable range to resist tool wear in the cutting process. Comparative experiments is carried out in PSG Lathe A141 with 2.2 kW power, and Cubic boron nitride inserts (CBN) KB-90 grade for cutting 6061 Al-SiCp Metal matrix composites with SiC 15% volume fraction and 25μm particle size. The effects of steam jet under different directions and dry cutting on tool wear at different Cutting speed, Feed and Depth of cut have been investigated
