Numerical controlling unit

A numerical controlling unit that accelerates or decelerates a feeder-driving system, comprising:

• an acceleration setting part that can set a value 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,
• wherein the acceleration setting part is adapted to set a first acceleration having a first value that starts to be supplied at a first timing of starting to accelerate, and
• a second acceleration that has a second volume and that starts to be supplied at a second timing while the first acceleration is being supplied, the second value and the second timing being determined so as to damp vibration of the feeder-driving system that is generated by starting to supply the first acceleration, wherein:
• the acceleration setting part is adapted to further set a fourth acceleration that starts to be supplied at a fourth timing of ceasing to accelerate, and
• a third acceleration that has a third value and that starts to be supplied at a third timing before supplying the fourth acceleration, the third value and the third timing being determined so as to generate vibration of the feeder-driving system that is damped by starting to supply the fourth acceleration while the third acceleration is being supplied.

• the second timing at which the second acceleration starts to be supplied is a moment wherein an amplitude of the vibration of the feeder-driving system caused by the first acceleration is raised to zero.
