Taguchi Optimization of Machining Quality in Step Drilling of Composites Based on Membership Function

Abstract:

Delamination-free hole is expected for composite parts using optimized drilling parameters due to an increase in composite structures production and in the need for higher quality machining. The influence of the various machining parameters (step angle, stage ratio, feed rate and spindle speed) on thrust force and equivalent delamination factor in step drilling composites was investigated in this study. The use of membership function based on Taguchi method to obtain the optimization of the process parameters by considering multiple performance characteristics has been reported. Finds based on the membership function show that the lowest thrust force of step drilling composites to be about 25.6 N and equivalent delamination factor about 1.005 pixel/pixel.
