Abstract

In this study, during the machining of metal matrix composites produced by a hot pressing method in CNC milling, the effects of cutting parameters and coating type on the surface roughness were experimentally and statistically investigated. The production of composite samples was accomplished by hot pressing, in which Al was used as the matrix element and 10 % SiC particles were chosen for the reinforcing phase. In the machining of samples, three different cutting tools (uncoated, multi-layered and Nano TiAlN coated), three different cutting speeds (60, 78, 101 m/min) and three different feed rates (0.04, 0.08 and 0.12 mm/rev) were employed. Full factorial (3(3)) experimental design was chosen for the statistical investigation of the cutting parameters and parameter interactions. The response surface method was used in the mathematical modelling of the surface roughness obtained from the experiments and in the optimisation of cutting parameters. At the end of the study, the cutting tool's wear was evaluated and the wear was discussed by comparison with similar studies.
