ABSTRACT:
A method and apparatus for cutting sheet material utilizes a closed loop automatically controlled cutting machine having a reciprocating cutting blade as the cutting tool. Sheet material to be cut is spread in multiple plies to form a layup, and the cutting blade and the material are then moved relative to one another in cutting engagement along predefined lines of cut. During cutting, a sensor detects a cutting parameter that is affected by the interaction of the cutting blade and sheet material, and signals provided by the sensor are fed back in the closed loop automatic control mechanism to adjust or initiate further steps in the cutting operation. Such adjustment or initiation alters the cutting machine operation for cutting conditions in real time in order to improve the overall performance of the machine.
