PCT No. PCT/JP90/00902 Sec. 371 Date Feb. 27, 1991 Sec. 102(e) Date Feb. 27, 1991 PCT Filed Jul. 12, 1990 PCT Pub. No. WO91/01518 PCT Pub. Date Feb. 7, 1991.A numerical control apparatus for adaptively controlling a servo apparatus, wherein a load current (Ln) and a velocity (Vn) of a spindle motor (74) are used as a fuzzy input. In response to the fuzzy input, a fuzzy control means (80) effects a fuzzy inference to output a velocity control signal (Cng) for controlling the velocity of the spindle motor (74). This control of the velocity of the spindle motor (74) with the velocity control signal (Cng) makes it possible to effect a smooth velocity control.
