Abstract
PURPOSE: To cut a material into accurate length by calculating a correction coefficient from observed feeding length of the material; thus obtaining the real displacement of the material, and applying this displacement as one of control signals, rotation of shearing cutters is controlled.
CONSTITUTION: When a thickness of 2H of a work 2 is given to a setting device 17, an arthmetic circuit 14, used for detecting the start of cutting operation, counts up pluses coming from a pulse transducer 13 during a period of time required for a tooth of a shearing cutter 4 to rotate an angle θ from its upper dead point 16 to a point on the work 2. A fixed-distance arithemtic circuit 22 calculates the fixed distance Lo, and its output is sent to a correction coefficient evaluation circuit 21; with its output, or a correction coefficient, real displacement of the work 2 is calculated. Thus applying this real displacement as one of control signals, a shearing cutter drive motor 11 is controlled, resulting rotational speed control of shearing cutter 4 and 4'. A calculation circuit 24 calculates the real length of the work 2 to be cut, and a correction circuit 28 corrects errors.
