When developing machining processes, it is necessary to select the optimum machining conditions (such as tool conditions, cutting speed or feeding speed), as well as select an efficient machine and process to be used. Quality engineering methodology recommends evaluating the performance of machining milling or drilling processes by directly or indirectly observing the energy consumption. In this study, the evaluation of machining a stainless steel part was made by measuring the total power consumption of the main motor. However, the gain was not very reproducible. Therefore, the variation of the energy consumed during idling time was included in evaluation. The results showed a good reproducibility of gain. Under the optimum conditions, the dimensions after machining were uniform and the surface roughness was also improved.
