A new alloy our company recently developed is lightweight and has an excellent heat resisting property, but it is diffcult to process causing rough finishing surface,tool wear or tool breakage. Sometimes it was impossible to process. A drilling process was studied for improvement using electric power as a means to evaluate drilling function. Since the power consumption during the pre-drilling,mid-stage drilling and final drilling is different, analyses were separately conducted for each stage. A very good reproducibility of conclusions was found. The results were applied to mass production resulting a good stability for the process and a 50% speed increase.
