Further, the NC program execution section 51 is connected to a turret punch press control section 83 for controlling the operation of each drive member of the turret punch press 9.

With reference to FIG. 7, a description will be given of a data flow in the case where the mold is automatically replaced in the above configuration. In step 501, the worker 21 inputs mold information to the used mold information input unit 53 of the ATC control device 1 in accordance with the machining instruction 6 in which the molds to be used are summarized based on the machining contents of the work W. . In step 503, the mold exchange mold search unit 61 determines whether there is a mold to be exchanged on the upper and lower turrets 25 and 27 based on the input mold information. If the mold exchange is not necessary, that is, if all the used molds are mounted on the upper and lower turrets 25 and 27, the automatic mold exchange process ends.

In step 505, the mold information which needs to be replaced and is searched in step 503 is displayed in the mold information display section 8.
Displayed at 1. In step 507, the tool rack tool search unit 65 searches whether the tool to be replaced is housed in the tool rack 15. If the tool to be replaced is found, the tool list is added to the tool list. The information is displayed on the information display section 81 (step 509). If the mold to be replaced is not found, the automatic mold replacement process ends.

Based on the confirmation of the exchange mold, automatic exchange of the mold by the ATC 19 is performed. In this case, a mold can not be automatically replaced by ATC19 is displayed in the mold information display unit 81 through the mold manually exchange list generator 6 9 (Step 51
5). The turret layout information updating unit 77 and the tool rack mold information updating unit 79 update the mold information (step 517).

At step 519, it is determined whether or not the operator 21 manually replaces a mold that cannot be automatically replaced by the ATC 19, and if so, the mold is replaced by the worker 21 (step 521). If the mold is not replaced, the mold automatic replacement process ends. In step 523, the mold to be exchanged is confirmed by the mold information confirming unit 55, and the automatic mold exchange process ends. In parallel with this confirmation work, the turret layout information is updated by the turret layout information updating unit 77 (step 525).

As described above, the mold information mounted in the upper and lower turrets 25 and 27 and the mold information in the tool rack are registered as a database in the ATC controller 1, and the operator 21 registers the NC program 3 Required mold at ATC
Only by inputting to the control device 1, it is possible to automatically search for a mold to be replaced and replace the mold.

[0030]
