Abstract:
A numerical controller can suppress overshoot in adaptive control and includes a speed calculation unit and a spindle load correction unit. The speed calculation unit performs PID control to adjust a feeding speed based on a spindle load measured by a measurement unit. The spindle load correction unit corrects the spindle load so as to have a value close to a target load until the spindle load reaches the target load. The speed calculation unit performs PID control using the corrected spindle load.

Claim (Index 3):
The numerical controller according to  claim 1 , wherein\n the spindle load correction unit is configured to correct the spindle load based on a ratio between a length of a chord of an arc, which indicates a contact surface between a tool and a workpiece, and a diameter of the tool.
