Title:
A control method and an NC machine tool of a sending axis
Document Type and Number:
Japanese Patent JP6275245
Kind Code:
B2
Abstract:
Provided is a feed shaft control method, wherein a speed feedback loop having a speed controller (72) is disposed within a position feedback loop having a position controller (71), forming a cascade coupling, and an acceleration feedback signal which is outputted from a compensator (91) on the basis of an output signal of an acceleration detector (60) is subtracted from a torque instruction (Är). Furthermore, the method implements control wherein a speed is acquired on the basis of the output signal of the acceleration detector (60), and a signal obtained by multiplying the acquired speed by a gain (Ka3) is added to a speed instruction (Ér) which is outputted from the position controller (71).
