Abstract

PURPOSE:To edit a processing program at the side of a machine interface by providing an editing operation part consisting of a display device and a keyboard to the machine interface device. CONSTITUTION:An editing operation part 25 consisting of a keyboard 26, a display device 27 and an alarm buzzer 28 is connected to a terminal control part 24 of a machine interface device 14. An operator delivers an input through the keyboard 26 and designates a desired program name out of the storage data on a processing program in the device 14. The contents of the program are displayed to the device 27 to perform editing of the program with correction, additions and subtractions. Thus an edited program is stored into a memory 16. A CPU15 sends the edited processing program to an NC device 13 from the memory 16 via a BTR interface circuit 17 with each character and at and after the head block of the program.

If downloading is not possible, a downloadable answer is sent to the host computer system 12, and if downloading is possible, a download permission answer is sent to the host computer system 12 via the host interface circuit 20.

When the download permission response is received, the computer program is downloaded from the host computer system 12 to the machine interface device 14 via the host interface circuit 20Y, and stored in the memory 16 of the machine interface device 114.

If no error is detected and the data is stored in the memory 16, the host computer system 12 is notified that downloading is possible via the host interface circuit 20Y.

Next, when the machining start conditions are established in the host computer system 12, as shown in FIG. Instructions are given. Machine interface device [1
The central processing unit [15] of No. 4 confirms whether the search-instructed Canadian program is stored in the memory 16, and if so, sets a pointer to the first block of the program. Upon completion of setting the pointer, the host computer system 12 via the host interface circuit 20
Report the completion of a Nibrogram search.

Next, the host computer system 12. Upper interface circuit 20 for the mechanical interface device t14
Since a processing instruction is given via Y, the machine interface device 14 sends an automatic production signal to the NC device 13 via the contact interface circuit 19, and then the NC

Since a start-up request (FWD) is given, the central processing unit 15 of the machine interface device t14 processes the NC device 13 in character units from the first clock of the computer program instructed by the host computer system 12 via the BTR interface circuit 17. Send to.

Similar to the above-mentioned tape operation, the NO unit [13 stores the contents of one block of the program in the read-ahead buffer area of the memory 2 via the interface circuit W&6' and stops sending the BTR activation request (FWD). . The contents stored in the pre-read buffer area are transferred to the work buffer 7 area, and the J:9 machine tool 9 is operated and controlled by the machine tool control system *1o according to one block's worth of programming. On the other hand, *, when the reading buffer area becomes empty,
The BTR origination request (FWD) is sent again to the machine interface device 14 and stored in the buffer 7 area for pre-reading the additional p-grams for the next program. Working buff 7
When the machining work for one block stored in the area is completed, the machining program for the next block stored in the pre-reading buffer 7 area is transferred to the work buffer area again and the machining work is performed. Hereafter, this process is repeated twice, and the photons are used to perform the processing process.

Further, as shown in FIG. 2(e), a seven-part broadcast instruction for the Canadian program is given to the host computer system 12 and the machine interface device t14 via the host interface circuit 20.
