PROBLEM TO BE SOLVED: To provide a controller for a machine tool having a consumed electric power reducing function, which can reduce a consumed electric power in the whole of the machine tool including peripheral devices. SOLUTION: A timer is reset to zero, then turned on and the measurement of a cycle time and the consumed electric power are started to measure the initial value of a thermal displacement (SA100 to SA103). A block of a working program is read to analyze and execute the block. The timer is turned off to finish the measurement of the cycle time and the consumed electric power and the thermal displacement is actually measured (SA104 to SA109). The cycle time, the consumed electric power and the thermal displacement are calculated and stored, and a parameter set is changed to repeat the calculations setting number of times (SA110 to SA113). Then, the cycle time, the consumed electric power and the thermal displacement are displayed on a screen and the parameter set is selected in accordance therewith to execute the working program on the basis of the parameter set (SA114, SA115).
