Abstract
At the time of two-dimensionally moving a mobile body of a machine tool, to a predetermined position, a speed of the mobile body is gently increased/decreased at an acceleration/deceleration equal to or less than the maximum acceleration/deceleration, from the time when the mobile body reaches a direction change point. Therefore, the moving time is shortened and a rapid acceleration/deceleration may be avoided.
