The invention provides an energy consumption prediction method for a numerical control lathe in a turning procedure. The method comprises the following steps that 1) the standby power of the numericalcontrol lathe is determined, and a main-shaft zero-load power calculation module of the numerical control lathe is established; 2) cutting fluid pump power, tool changing energy consumption and toolchanging time of the numerical control lathe are determined; 3) an energy consumption calculation method of the numerical control lathe is established; and 4) according to the turning procedure, the blank size and technical parameters, the energy consumption of the numerical control lathe in the turning procedure is calculated. Compared with present methods, the method of the invention has the advantages that energy consumption of the numerical control lathe is divided into main-shaft zero-load energy consumption, cutting energy consumption, tool exchanging energy consumption and standby energy consumption; the main-sh
