Abstract

As a consequence of widening range of applications of metal-matrix composites (MMCs), the machining of these materials has become a very important subject for research. 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 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 turning age hardened 6061 Al-SiCp Metal matrix composites with SiC 15vol.% and 25μm particle size. The effects of steam jet and dry cutting on four selected samples on chip and built up edge formation at 150m/min Cutting speed, 0.2mm/rev Feed and 1.5 mm Depth of cut have been investigated
