Abstract
A wire electric discharge machine has a function for controlling the machining liquid temperature. When it is predicted that the machining liquid temperature rises linearly, the machining liquid begins to be warmed at time tto reach machining liquid control temperature Tat human operation beginning time t. If the temperature rise at predetermined later time tis greater than predicted, temperature rising suspended from time tto a later time t. Temperature rising resumed at time t. This allows the machining liquid temperature to reach the machining liquid control temperature Twithout wasting electric power.
