There is a very complex nonlinear relationship between cutting parameters and machine tools energy consumption in CNC machining process. The general formulas are very complex from experience; it needs the experience tables and complex and tedious calculations to estimate energy consumption. This paper proposes a CNC machine tool cutting process model for… (More)
