Abstract:
The utilization of unconventional machining methods such as electron beam machining, electrical discharge machinating, etc., have been increased in the manufacturing industry to drill accurate holes on the materials. But still the In this paper, twist drill was used for drilling of Bahunia racemosa (BR)/ glass fiber composites and then the measurement of hole diameter accuracy was analysed. The main objective was to establish a correlation between feed rate, cutting speed and drill tool with the induced hole diameter accuracy in a composites. The drilling process was performed under various cutting speed, feed rates and different drilling tools with a point angle of 1180. A Coordinate measuring machine was used to examine the hole diameter accuracy of drilling hole. Taguchi L9 (33) orthogonal array was used to determine the optimum levels of the parameters and analyze the effect of drilling parameters on hole diameter accuracy. The optimal combination levels and the important drilling parameters on hole diameter accuracy were obtained using ANOVA. The results showed that the higher cutting speed, lower feed rates and HSS brass coated tool are essential to minimize the hole diameter accuracy.
