<p>PURPOSE:To input a work in advance and to increase the operation rate of a machining center, by performing a work input forecast of each machine based on the actual work time, a standard work time in the initial case of a lot and the work time of the previous time in case of being within the lot. CONSTITUTION:A work input forecasting means 3 reads a work time from a standard work time table 2 in case of the initial work, performing the work input forecasting of a machine by subtracting in order the actual work time by a work time monitor means 1. A work is then input aiming for the time when an input stage is open in case of the work by other machining center MC being progressed, the initial actual work time is obtained at the work completion time and the work time of this time is stored in a memory for using it at the next time. In case of no initial work of the lot, the actual work times up to the present time are subtracted in order similarly from the previous time work actual work times and the work input time is forecast based on this value.</p> |
