Abstract

In a system for working a blade material for a mold, the product size, material, etc. concerning individual blade materials to be worked is registered in a computer in advance, and a method of setting up the blade material to be worked is instructed to the operator by the computer. An NC working program is compiled automatically so that the operations of the machine are sequenced in such a manner that the working of all the blade materials on one pallet is completed most speedily after data on dimensions concerning the difference between the design values of the basic material obtained during the setup and measured values is input to the computer. The automatically compiled NC working program is collectively downloaded to an NC machine tool via a communication line. While the operator is setting up the basic material on one pallet, the blade material which has been set up on the other pallet is worked in accordance with the NC working program, thereby allowing the working of blade materials to be effected efficiently by the NC machine tool.
