<p>PURPOSE:To improve the working efficiency by designating a group of numerically controlled machine tools for each type of parts and allocating the parts to said machine tools waiting for working within a group to perform the working. CONSTITUTION:For instance, the schedule data SA and the working process data SB are set and three numerically controlled NC machine tools M/C1-M/C3. In this case, the parts having parts numbers A are worked by the M/C1 and M/C2 as shown in a time table TT since the NC machine tool groups 1 and 2 are designated. Then the NC machine tool groups 2 and 3 are designated for the parts of parts numbers B. In this case, the M/C3 is not working. Thus the parts of the numbers B are worked by the M/C3. When the working is through for the parts of the numbers A via the M/C2, the parts of numbers B are worked. While a parts of a parts number C is worked after the working is through with the parts of numbers A via the M/C1 since an NC machine tool group 1 designated for the parts of the number C. Thus the working efficiency is improved.</p> |
