Abstract

The fiber reinforced epoxy composite industry today is experiencing significant growth. They are replacing several traditional materials used in building, sporting equipment/appliances, automotive/aircraft parts, boat and canoe hulls, and bodies for recreational vehicles. It offers many advantages over traditional materials: important among these are high strength, light weight, flexibility in design, parts consolidation, dimensional stability, corrosion resistance and low tooling costs. However, during the dry drilling operation on composites, drilling induced damage drastically affects the performance of the drill tool. The present investigation is an attempt to study the effect of the drill process parameters like the spindle speed (1000, 1200 and 1500 rpm), the feed rate (0.1, 0.2 and 0.3 mm/rev), the drill diameter (6, 8 and 10mm) and fiber orientation (Random, Random+Stitched and Random+Rowings) on the tool wear of the HSS drill bits in dry drilling of glass fiber reinforced polyester composites. The settings of the process parameters were determined using Taguchi‟s experimental design technique. Orthogonal arrays of Taguchi, the Signal-to-Noise (S/N) ratio, the Analysis Of VAriance (ANOVA), and regression analysis are employed to find the optimal process parameter levels to minimize the tool wear and to analyze the contribution of each of these process parameters on tool wear.
