NUMERICAL CONTROL DEVICE

A numerical control device includes a drive-shaft movement-amount estimation unit to estimate a first movement amount of a first object that is a target to be moved by a first drive shaft by using a first drive signal, an undriven-object movement-amount estimation unit to estimate a second movement...

Beschreibung
Zusammenfassung:	A numerical control device includes a drive-shaft movement-amount estimation unit to estimate a first movement amount of a first object that is a target to be moved by a first drive shaft by using a first drive signal, an undriven-object movement-amount estimation unit to estimate a second movement amount of a second object in a three dimensional space, which is generated due to a drive force of the first drive shaft, by using the first drive signal, a correction-amount calculation unit to calculate a correction amount for the first drive signal on the basis of the first movement amount and the second movement amount, and a first correction-signal output unit to output a first corrected drive signal obtained by correcting the first drive signal by the correction amount to a drive unit to drive the first drive shaft.
