Abstract
The present invention allows easy restarting of a multiple product machining function in interrupted punch press work. An interrupted machining position is identified with a product number set on a work and a product number of a product for which machine operation is stopped or a product number of a product to be next machined is entered. When this product number is entered, a command program is modified according to a product number entered. The modified program gives machining commands from a work position for a product other than the product for which machine operation is interrupted to a punch press machine.
Claims8
A method of restarting an operation of a punch press machine, which is controlled by a numerical controller having a function to repeatedly execute a set of specified machining programs based on different reference points as many times as specified, to thereby perform multiple product machining for machining a plurality of products from a single work, comprising the steps of:
- providing the numerical controller with a function of recognizing designation of a product number;
- providing the numerical controller with a function of restarting the repeated execution in accordance with the designated product number if the designation of the product number has been recognized upon starting of the execution;
- and
- designating the product number when restarting the operation of the punch press machine.
A numerical controller for controlling a punch press machine so as to perform multiple product machining wherein a plurality of products are made from a single work, by repeatedly executing a set of specified machining programs based on different reference points as many times as specified, comprising:
- means for recognizing designation of a product number;
- and
- means for restarting the repeated execution in accordance with the designated product number if the designation of the product number has been recognized upon starting of the execution.
