PURPOSE:To allow an operator to grasp the progress situation of executed working by displaying at least two kinds of times among a total working time, a progressing time and a remainder working time necessary for numerically controlled working in current execution at every machine tool. CONSTITUTION:A host device 201 inputs the number of a numerically controlled program, which is used for working a desired part, to the cell controller 202a of a working cell 202. The controller 202a inputs said number to a CNC (numerically controlled) device 202b and simultaneously an activating command to the device 202b, and starts counting at the same time. The device 202b reads the NC program specified by the inputted number out of a MEM (memory device) to execute a numerical control. In parallel to said execution the controller 202a displays at least two times among the total working time, the progressing time and the remainder processing time made by the NC program on a display device DSP. The controller 202a repeats such processing, stops the counting when it receives a working completion signal from the device 202b and stores the progressing time in a RAM. |
