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.

In a system for working a blade material for a mold including a machining center for working a workpiece, a setup station for setting up the working of the workpiece, a numerical value controller connected in such a manner as to control said machining center, and a computer system for providing information and data concerning the workpiece to said numerical value controller, a first pallet placed on a machine table mounted on said machining center being replaceable with a second pallet supporting the workpiece placed on said setup station via a pallet changer, a method for working a blade material for a mold comprising the steps of:

formulating information on tools to be used, data on machining conditions, data on individual blade materials, and date on a working schedule;
registering various said data;
instructing a setup for working the blade materials by said computer system in consecutively working the blade materials registered in accordance with said data on a working schedule;
setting up the workpiece placed on said second pallet on said setup station, and inputting data on the dimensions of the set up workpiece;
automatically formulating a machining program for each of said setup workpieces on the basis of the registered data on information and the input data on dimensions;
exchanging said second pallet for which setup has been completed and which is on standby for working with said first pallet for which working has been completed;
and working the blade material by downloading the automatically compiled numerical value control program to said numerical value controller;
wherein a cycle for implementing said various steps is repeated until the working of all the blade materials registered in said schedule is completed with respect to said pallet moved from said machine table side to said setup station side at the time of exchange of said pallets while the working of the blade materials is being carried out on the basis of said numerical value control program.
