Title: Casting scheduling making system
IPC: B23Q41/08
Filed: 1992-04-02
Abstract: PURPOSE:To make high accurate casting scheduling and to reduce cores in stock by considering the core-making load and applying knowledge treatment. CONSTITUTION:At first, casting arrangement data for each casting are transmitted to a work station 2 from a host computer 1. In the work station 2, the data are stored in data 3b for casting arrangement number. Successively, in this work station 2, the necessary number of flasks for each material and melting wt. at the corresponding day are calculated from the data 3b for casting arrangement number. Related to the melting wt., it is decided that any tons of molten metal in a melting furnace are necessary to melt. At this time, in the case the data for casting arrangement number exceed casting or melting capacity, the adjustment of the load is executed by interaction system, e.g. the number of casting flask is reduced. Therefore, in the consideration of the load of core, the high accurate casting schedule can be made, and based on the casting order schedule, simulation of the core forming load is executed and the cores in stock can be reduced.
