Recently, the demand to reduce the energy consumption of NC machine tools is increasing. In particular, revealing the energy consumption during cutting process is important, many studies have been accomplished. However, few studies have shown the relationship between the cutting force and energy consumption during cutting process. In this study, in order to clarify the relationship, measurement tests of the power consumption, motor toques and cutting forces are carried out during peripheral milling operations using square end mills. The tests are carried out with various material removal rate, down and up cuts, and different number of flutes. Losses of each part are evaluated based on the energy consumptions per one cubic millimeter material removal volume. As the results, it is confirmed that the energy consumption during the down cut milling is smaller than it during the up cut milling. It is also confirmed that the higher number of flute reduces the energy consumption.
