Abstract
A numerical controlling unit that accelerates or decelerates a feeder-driving system includes; an acceleration setting part that can set a volume and a timing of an acceleration that should be supplied to the feeder-driving system, based on a predetermined target condition; and a controlling part that can supply the acceleration set by the acceleration setting part to the feeder-driving system. The acceleration setting part is adapted to set: a first acceleration that starts to be supplied at a timing of starting to accelerate; and a second acceleration that has a volume and that starts to be supplied overlappedly with the first acceleration at a timing, the volume and the timing being determined so as to damp vibration of the feeder-driving system that is generated by starting to supply the first acceleration.
