[edit] Industry standard protocols

Does anybody know about the standards used for the files to control the CNC machines? ISO standard??

The simple answer is that there is no Standard. There are a couple of areas where there is an approximation of one.
  • Since the mid 1980s, the Electronics Industries Association (EIA) has published RS-494. It is a multi-part specification and has been partly adopted by the IEEE. This is probably closest to an industry standard.
  • ISO has only ISO/IEC 9506, Industrial automation systems - Manufacturing Message Specification which deals more with headers and encapsulation.
  • ISO also has ISO 10303, Industrial automation systems and integration - Product data representation and exchange, but this deals more with specs for the part being machined, while NC wants to look at the steps needed to machine it.
Sorry I can't get you a clear answer. The are a number of semiproprietary software solutions based around the RS-494 specification. --Lou I 15:02, 15 Sep 2003 (UTC)


The G-Codes are standardised in ISO 6983.
The newer ISO 14649 offers a feature based alternative.
ISO 14649 has been incorporated into STEP (ISO 10303) as the ARM for ISO 10303-AP238.

[edit] "The" Machine Tool Company

There's an external link to Mori Seiki subtitled "THE Machine Tool Company". That's a slogan from a marketing campaign and seems to be free advertising since there are literally hundreds of machine tool builders. In fact, Mori Seiki is one of the world's largest five or six machine tool companies, certainly not "THE" MT company. —The preceding unsigned comment was added by 24.223.223.235 (talk • contribs) .

Point taken, adjusted accordingly — Graibeard 05:59, 19 January 2006 (UTC)

[edit] Commercial links

The question has arisen about which commercial links belong here.

Are there too many of them here? -- ArglebargleIV 20:47, 14 August 2006 (UTC)

Commercial sites sometimes have interesting information on them, links should point to those parts of those sites. —Preceding unsigned comment added by 196.2.124.251 (talk • contribs) 16:37, 27 August 2006

I'm about to go through and remove all linkspam, which is really bad on this page. I figure I'd give 24 hour notice for anyone watching this for comments/concerns. - Toastydeath 22:29, 22 November 2006 (UTC)

Please do! This article suffers from advertising. Perhaps a good idee to list below the removed advertisment links and the IP adres that posted them. This way repetitive spammers can be detected and warned. --Jurriaan van Hengel 07:46, 23 November 2006 (UTC)
I went through everything, and most links were outright spam. Going back through the history and trying to find all the edits that added the links would be difficult and time consuming. I'm content to just remove them now, and nail the spammers when they return. That being said, here is some removed stuff I felt had no real bearing on the topic of CNC, but may be useful in other articles:
And conversely, here is stuff I left IN which people might object to, with an explanation of why I left it:
  • CNC Zone, Large DIY CNC forums - I thought keeping this might be a fairly good resource to anyone looking for CNC help/etc that wikipedia does not provide.
  • The Enhanced Machine Controller, open source CNC control software - It has a machine emulator, so someone wishing to learn in-depth CNC/G-code programming can use this for free, hands-on experience.
If anyone objects to the flow-forming/metalspinning links, I'd vote to remove them. They have basically nothing to do with the article, but I felt bad leaving just 2-3 links in the section.

[edit] Simplification?

I just came across this article via various random links, and noticed almost immediately that, in the way it is worded, to the average non-manufacturing/metallurgical/industrial engineering layperson, it is actually almost impossible to easily understand exactly what a CNC does without having to go much further out of one's way than should be required when looking for an encyclopaedic yet succinct account of a specific subject.

Assuming, as I do, that CNC's take and record all the required measurements of a master shape for sending to a tooling machine, would it not be useful to introduce the subject with a simple statement to such an effect - in laypersons terms - eg "a CNC is a computerised programming device allowing measurements from a master design which have been inputted into it to be fed into a cutting/tooling machine that will reproduce a specifically shaped/sized part accurately" or something to that effect - as it currently seems to be such a densely worded article thus making it almost entirely useless as a quick reference to anyone who would not already be quite clear as to what it is?!

[edit] Who buys them?

It would be very useful to include a section on who buys them, maybe with some generic examples. Thanks —Preceding unsigned comment added by 75.33.96.254 (talk) 00:04, 29 October 2007 (UTC)

[edit] Photo Caption

the caption for the Haas CNC reading "a low quality"... doesnt seem NPOV "We're just going to have to use our brains."............."Damnit." (talk) 13:23, 12 May 2008 (UTC)

You're right. Kevin (talk) 07:28, 13 May 2008 (UTC)
