Title:
ロール金型製造方法、ロール金型製造装置およびプログラム
Document Type and Number:
Japanese Patent JP7413001
Kind Code:
B2
Abstract:
A method for manufacturing a roll mold by cutting a roll, includes generating a control waveform based on a signal corresponding to a rotary position of the roll, and making a plurality of cuts on a surface of the roll by, while the roll is rotated, reciprocating a cutting blade in a radial direction of the roll in accordance with the control waveform. Making the plurality of cuts includes at each of a plurality of predetermined locations, making a predetermined number of cuts of predetermined depth based on the control waveform. Generating the control waveform includes generating a control waveform dictating that the predetermined locations, the predetermined depths, or both are randomly selected. Generating the control waveform includes generating a control waveform dictating that, when multiple cuts are made at a predetermined location, each subsequent cut will have a smaller depth than a preceding cut.
