0012 Next, the operation of the present invention will be explained in detail.

[0013] First, before the end of the day, workers must reset the workpieces and tools for unmanned operation at night. etc., and the time to perform maintenance, inspection, etc. during unmanned operation at night. Perform operations to input time signal data for setting.

[0014] This setting operation and setting process follow the procedure shown in the flowchart of FIG. sand That is, the worker uses the keyboard 2b of the data input/output device 2 (see Figure 2 and the same applies below). The time when a time signal should be output by operation, such as replenishing a workpiece or replacing a tool or tip. Setting time to set a time signal to notify maintenance and inspection times such as replacement and scraping of chips. time and work instruction information (work out) to be performed when the time signal is output at this set time. (replenishment of tools, replacement of tools and chips, scraping of chips, etc.) by matching time signals and work instruction information. and input it (step S1). This input time signal data is the main bus 1' (step S2), and this transferred time signal data is stored in the time signal memory. 3, and the time signal output time and work instruction information to be performed are set (step S3).
