Minimising tool wear by optimisation (ANOVA) of cutting parameters in machining of 7075Al Alloy SiC particle composite

Abstract

ABSTRACT In this experimental work, AA7075-15 wt. % SiC (10–20 µm) composite was made through stirring casting. Experiments were performed on this composite by tungsten carbide cutting tools of different nose radius at diverse cutting speeds, feed rate and depth of cut. Outcome of process parameters i.e cutting speeds, feed, depth of cut and nose radius on response i.e tool wear (flank & crater) was examined. Optimum amount of process parameters were obtained to minimise flank and crater wear using multi objective optimisation. According to outcomes of multi objective optimisation, optimum amount of cutting speed, feed, depth of cut and nose radius are 90.02 m/min, 0.15 mm/rev, 0.23 mm and 0.40 mm, respectively. Novelty this research is that little work is reported about optimisation of parameters while turning the AA7075-15 wt. %, to minimising tool wear. Aircraft, shipping and space industries demands machining with minimum amount of flank wear and crater wear.
