摘要： A numerical control device reads a machining program and causes a machine tool to operate based on the machining program. The numerical control device includes: an acceleration-deceleration determining unit; and a position-command generating unit. The numerical control device is configured to set the acceleration and the deceleration as acceleration-deceleration data when the acceleration and the deceleration satisfy tolerances decided based on actual mechanical dynamic characteristics, and set the tolerances as acceleration-deceleration data when the acceleration and deceleration do not satisfy the tolerances. The position-command generating unit is configured to generate a position command based on the moving command, the acceleration-deceleration data, and the speed at the end of the command route and the superimposition amount subjected to processing by the acceleration-deceleration determining unit.

摘要： A method and apparatus by which accurate correction values for thermal displacement is calculated even when the rotation of the main spindle is restarted after interruption. The apparatus has means 2, 3 for measuring the temperature near the main spindle 15, means 5 for estimating the thermal displacement of the main spindle 15 on the basis of the measured temperature and a predetermined thermal displacement calculation expression, means 7 for calculating the correction value, and means 6 which estimates the displacement delay in re-rotation caused by the interruption of the rotation of the main spindle 15, and calculates an adjusting displacement on the basis of the estimated displacement delay. The correction value calculating means 7 calculates a correction value on the basis of the thermal displacement estimated by the thermal displacement estimating means 5 alone when the main spindle 15 is started up and rotated.
