The Optimization of Drilling Parameters of Glass Fiber Reinforced Plastics Via Taguchi Method

Abstract

In the competitive world today, increasing importance of conservation of energy have directed designers and engineers into search for light and mechanically high resistant material when choosing material. Glass Fiber Reinforced Plastics (GFRP) are polymer based materials made of reinforced with fiber glass. GFRPs are strong and light, showing resistance characteristics similar to metallic materials. Furthermore, the rates of the density of strength of materials are higher in comparison to metallic material. Therefore, their use has been increasing in aviation industry, wind power plant and marine applications every passing day. Assembly based process stages are used especially in aviation industry and wind power plant. In order to assemble, making a hole by drilling or CNC milling are common methods. So as to manufacture products in the required quality in making a hole in the GFRP, it is necessary to optimize cutting performance and conditions. This study aims at evaluating delamination factor in the GFRP. This study focuses on investigation, analysis and evaluation of the delamination factor in the GFRP using high precision metrology techniques that have been an indispensible part of the advanced production engineering. The parameters affecting the quality and accuracy of the workpieces are defined and experimental measurements are carried out to develop procedures in order to improve the quality and accuracy of the workpieces and machining processes.
