Abstract
A roll manufacturing apparatus includes a rotary device including a rotary encoder, a cutting tool stage that holds a spindle unit, which includes a rotatable cutting blade, reciprocatably in a radial direction of a roll and is movable in the radial direction of the roll, a signal generator that generates, based on signals output from the rotary encoder, a control waveform indicating a movement pattern to reciprocate the cutting blade at positions corresponding to predetermined cutting portions, and a controller that moves the cutting tool stage so that a cutting process of reciprocating the cutting blade in the radial direction of the roll while rotating the cutting blade, according to the control waveform, to perform cutting once or multiple times with the cutting blade at a predetermined cutting depth is performed multiple times.
