Optimization of Drilling Parameters for GFRP with Full Factorial Method

Abstract

Drilling is the most commonly applied method for hole making of fiber reinforced materials owing to the need for structure joining. GFRP is required a high quality drilling parameters due to its application in research and development, aerospace, marine, delegate furniture, roof, bridge construction, etc. This study had been given a new approach to optimize the drilling parameters such as thrust force and delamination through DOE by using full factorial design. The purpose of this study is to investigate the influence of drilling parameters, such as cutting speed, feed and Thickness of material on torque, thrust force and delamination produced when drilling different a thickness of GFRP composite sheet. It had been regression analysis and ANOVA to analyze and optimize the process parameter of drilling. From the results it has been observed that the significant effect of thickness, speed and feed on the responses thrust force, torque and circularity. It has been concluding that the minimum thickness, speed and feed given the optimum result of thrust force. The minimum speed, thickness and median feed given a optimum result for torque. The maximum speed median feed and minimum thickness given optimum result for circularity.
