If there is no abnormal tool, the process proceeds to the next tool life check. If there is an abnormal tool, the number of abnormal tools is displayed, and the pot number in which the abnormal tool is stored is displayed. For example, as shown in FIG. 7, a pot number (No) of an abnormal tool is displayed as a program number, the number of abnormal tools, and an abnormal tool list. Then, the process proceeds to the tool life check, and if there is no tool life check, the program check ends. If there is a tool life check, each data of the designated pot number (or tool number) is read out from the tool data storage unit 38, and the usage time and the life time (the remaining life obtained by subtracting the usage time from the initial life) are read from this data. Possible time) is displayed. For example, as shown in FIG. 8, the pot number, the usage time, and the life time are displayed.

Therefore, according to the present embodiment, when a program check of a machining program is commanded at the setup station STDD, the machining section control device 31 of the machining station STMC executes the current machining while executing the designated machining. Check the tool used in the program for abnormalities,
Since the result is transmitted to the setup station STDD, the machining program can be checked at any time in the setup station STDD. For this reason, even if an abnormal tool is detected by the program check in advance, maintenance or tool replacement of the abnormal tool can be performed before machining of the specified work W is performed, so that downtime of machining can be reduced.

In the program check of the machining program, the number of abnormal tools and the pot number of the tool magazine 14 in which the tools are stored are displayed.
Quick and efficient response to tool maintenance and tool change.

When a pot number is designated and a tool life check of a tool stored in the pot is instructed, the usage time of the tool and the life time (remaining usable time) are given.
Is displayed, it is possible to foresee in advance a tool that is likely to become abnormal. Therefore, from this point as well, the downtime of processing can be reduced.

In the above-described embodiment, the program check can be performed only at the setup station STDD. However, the program check may be performed at the machining station STMC. Further, in the above embodiment, the tool abnormality is determined based on the usage time and the wear amount of the tool. However, a tool breakage may be detected to determine the tool abnormality.
