An enhancement of the machining performance of GFRP by oscillatory assisted drilling

Glass fiber reinforced plastic (GFRP) composites are finding their way into high technology applications. The machining of GFRP composites is needed to produce near nett-shaped components. Damage free machining is necessitated for the longer inservice life of composites. The present study attempts a newer technique of the oscillatory vibration assisted drilling of GFRP composites in order to minimise the damages. For comparison, conventional drilling also has been carried out. The cutting performance is analysed through online studies such as the measurement of force, power and A.E. monitoring and through the measurement of tool wear as an offline technique.
