The Impact of Machining Parameters on Peak Power and Energy Consumption in CNC Endmilling
Year: 2013
Type: article
Abstract: Machining in a production environment commonly relies on trying maximizing material removal rates (MRR). This is done at the expense of increased peak power loads on the machine tool and machine spindle, and at the expense of potentially increasing energy consumption. To begin to develop an understanding of the relationship between peak power and energy consumption with machining parameters, spindle and total machine tool power are measured directly during a series of dry and wet endmilling tests on a 3-acis CNC milling machine. Cutting speeds, feedrates, and endmill immersions are varied and the resulting peak power measurements analyzed. Increasing any one of these parameters increases MRR and the peak power loads of the spindle and machine tool. However, the actual energy consumption varies widely for each parameter and in some cases such as when we increase feedrates, can actually decrease dramatically. The results of the direct measurements are presented and discussed as they relate to metal cutting.
