摘要

A method of cutting sheet material with an automatically controlled cutting machine having a reciprocating cutting blade utilizes a schedule of auxiliary or supplemental machine motions to modify the basic or fundamental motions of a cutting blade and the sheet material under selected cutting conditions. The supplemental motions and corresponding conditions are determined in advance by means of cutting improvement tests and are recorded in a schedule correlating the motions and corresponding conditions. During subsequent cutting operations, the special motions are selectively extracted from the schedule as the corresponding cutting conditions arise, and the motions are then employed to improve the overall cutting process.
