The corrected program is recorded on the IC card 17 then and there.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a program system for a numerical control machine, and uses an IC card as a medium for storing program data to be input to the numerical control machine.

In recent years, if the minute hand is machined using lathes, milling machines, etc.
Eric Contro1 machine (hereinafter referred to as NC machine) has been developed, and CNC machines (computed NCI, etc.) that have computer functions that can also store programs have also appeared.

Conventionally, when machining is performed using an NC machine, the program is mostly read from a paper tape into the memory of the NC machine.

The length of the paper tape is around 300m (approximately 960 pitches 1-11
12jO step) to 9 with options etc.
00m (approximately 2880 pitches, 33750 steps). Generally, it is about 20 to 30 m (64 to 96 bits).

Such paper tapes have the following problems.

(1) Due to the material, paper tape has drawbacks such as being weak against water, oil, etc. and easily tearing, so care must be taken when handling and storing it.

(2) To store paper tapes, it is necessary to separate them into plastic cases or the like, or to put them in boxes with compartments, which requires a considerable amount of space.

(3) Each program (paper tape) must be accompanied by a program list with instructions such as the offset position of the tool shape tool, and there are problems such as where to store these.

(4) Paper tape wears out when used many times, so it needs to be renewed.

(5) With paper tape, if there is a mistake in the program, you have to recreate everything. In addition, when an error occurs, the program stored in the memory of the numerical control machine is corrected by the operator on site, and the work itself continues.

Recently, some NC machines have been using floppy disks or bubble cassettes as storage media instead of paper tapes, which have the drawbacks mentioned above. However, floppy disks have limitations such as the need to install them in locations with little dust and vibration. Furthermore, since bubble cassettes do not have a CPU, they cannot be written on without a device called a bubble writer, and corrections cannot be made on site. Therefore, when a partial modification is developed, there are restrictions such as having to rewrite the entire program contained in the bubble cassette.

SUMMARY OF THE INVENTION In view of the above-mentioned prior art, it is an object of the present invention to provide a program system for a numerically controlled machine that allows programs to be easily modified on-site and is resistant to vibrations and dust. The present invention achieves this object by using an IC card as a storage medium for storing program data.
It is characterized by storing data on the card.

For this reason, when machining is performed using a numerical control machine (NC machine), a program is read from an IC card into the memory of the NC machine to perform the machining. If there is a mistake in the program, the program stored in the memory of the NC machine is corrected and the corrected program is recorded on the IC card on the spot. This type of IC card has no moving parts, so it is not affected by dust or vibration. Also, unlike paper tape, IC cards do not need to be updated. It is also possible to modify the program stored in the memory of the NC machine and record the program on the spot.Furthermore, the IC card can be
Since the tool shape, tool offset value, etc. are also recorded, there is no need to attach an instruction manual, so storage space can be reduced.
