Claims

[Scope of Claim for Utility Model Registration] 1. In a numerically controlled plate processing machine that performs processing such as drilling, cutting, tapping, drawing, etc. by attaching the end of a plate to a plate transfer and positioning device and positioning it by numerical control, the plate A pin-shaped measuring element abutting one side edge is provided so as to be vertically retractable by a driving means, the driving means is supported so as to be horizontally movable in a uniaxial direction, and the amount of this horizontal movement is detected. and a position detection rod that detects the amount of backward movement of the detection rod when the plate is positioned by the transfer positioning device and one edge of the plate comes into contact with the measuring tip and is moved backward. A movement amount detection device configured to do so is placed in the plate processing machine with the direction in which the detection rod can move parallel to the X-axis and Y-axis of the plate processing machine, and before processing the plate. , moving the plate by a predetermined amount in the X-axis and Y-axis directions to bring one edge of the plate into contact with the probe of the detection device;
Based on the detection signal obtained by the detection device, calculate the dimensions of the plate mounted on the plate material transfer and positioning device, and check whether the calculated plate dimensions are appropriate for the plate size values inputted in advance. A numerically controlled plate material processing machine characterized by being provided with a discriminating means for discriminating. 2. A machining program based on sheet material dimension values that are input based on a machining origin fixedly provided in a numerically controlled sheet material processing machine in response to a detection signal obtained from the detection device according to claim 1. A numerically controlled plate material processing machine characterized by having a correction means for correcting the processing program to an appropriate processing program. 3 Based on the detection signal obtained from the detection device according to claim 1, calculate the dimensions of the plate mounted on the plate moving and positioning device, determine whether the calculated dimension values are appropriate, and determine whether the calculated dimensions are appropriate. A numerically controlled sheet material processing machine characterized by comprising a correction means for correcting a machining program input in advance to an appropriate machining program based on the calculated value at a certain time.
