SPACE buffering in DNC Unit

[Ashish B]

Hi,

I was wandering that how DNC Unit Interprets a NC program with SPACE characters.

For Example -

N1 G90 G54 G90 G17
N2 M03 S500
N3 G00 X40.0 Y40.0 Z20.0
N4 G01 Z-2.0 F500
N5X52.075Y-103.576
N6X50.063Y-103.019
N7X49.843Y-102.854
N8X47.612Y-101.915
N9X45.380 Y-100.739
N10X44.404Y-100.050
N11G0Z39.014
N12 G1X44.019Y-115.923F9900
N13G0Z37.014
N14G1Z35.717F500
N15X44.513Y-116.306F3000
N16X48.296Y-114.177
N17 X49.843Y-113.585
N18X54.306Y-112.398
N19X58.770 Y-112.104
N20X63.233Y-112.579
N21X65.464Y-113.216
N22X67.696 Y-113.958
N23X69.927Y-114.982
N24 M05
N25 M30

IS IT POSSIBLE FOR A DNC TO INTERPRET THE Above mentioned program correctly ?

Thanks

What is a DNC unit?

If you mean a CNC control I believe a Fanuc will "interpret" the program correctly.

Thanks for your reply.

Older systems (Like 6M Control) don't have sufficient memory to interpret BIGGER SIZED Programs. It may be a NC Program created from a CAM software.

So, DNC Unit works as a OBJECT to read the Huge NC programs from personal computer, buffer it properly & then pass it on to the MACHINE CONTROL.

Machine control executes the program accordingly.

I hope that I was not too confusing.

Thanks

I know what DNC is, I've just never heard it referred to as a "DNC unit".

Any IDEAS on the problem mentioned by Me.

What PROBLEM?

[Ashish B]

I had the doubt that will the DNC Unit buffer properly a NC Program which has irregular spaces between the codes.

Thanks

According to the Fanuc 0M-C manual, spaces are ignored unless they are within a comment:

"If it is used in a statement other than a comment, the character will not be registered in memory. If used in a comment, it will be registered in memory."

Thanks Dcoupar,
For that valueable information & insight on buffering pattern of a NC program.

Thanks
