Investigation of Machinability of Composite Materials

Abstract

The machinability of composite materials mainly depends on matrix properties , reinforcements, cutting tool geometry and cutting parameters. Composite developments are increasing day by day and for each new composite the experimental study must be needed in order to understand its behavior against machining process and thereby help manufacturers to established data base for machining. In this study investigation is conducted to results the effects of cutting parameters (feed, speed) during drilling of carbon fiber reinforced polymer sandwich with Glass fiber reinforced polymer. It was found that feed rate and the spindle speed have significant impact on delamination of laminate and results surface roughness. The effect of machining parameters on delaminated areas are significant. The optimum parameters result in almost less delamination and fine surface roughness.
