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.
