::2.1.2 '''computerized numerical control CNC''' - realization of NC (2.1.1) using a computer to control the machine functions (2.6).

::So the ISO recognized definition of CNC is ''computerized numerical control'' [[Special:Contributions/130.76.112.25|130.76.112.25]] ([[User talk:130.76.112.25|talk]]) 13:13, 28 July 2022 (UTC)

::: This entire article is kind of garbage. NC != CNC. I should put that in bold. Many (most ?) of the people commenting here do not have a clue. Numerical control came out in 1952 - actually the project started in the 1946-ish time frame but the first functional example was 1952. Numerical control happily went along making parts until the mid seventies, that's like twenty years, when (bold) for the first time (end bold) a computer was put in the box with the rest of the electronics creating, as mentioned above, "computerized numerical control". Can we say this again ? NC != CNC. CNC has a computer in the MCU (machine control unit). NC does not. I've owned both. They ain't the same thing, not by a long shot. This entire article is fubar.

::::: I'm happy for them. The MIT converted hydrotel (first nc machine ever) was running and making 3D ashtrays in 1952. The ashtray was their sample part handed out at conferences showing this new method of machine control. You can maybe find photos online. Times have changed.

::::: 1961 is way late, several US machine tool builders had machines widely available, for sale, in trade shows, several years before that. [[Special:Contributions/203.160.68.123|203.160.68.123]] ([[User talk:203.160.68.123|talk]]) 05:06, 21 June 2024 (UTC)

[[:Numerical control]] → {{no redirect|Computer numerical control}} – The most common usage for this technology is CNC. Even this articles uses that abbreviation. What does CNC stand for? Computer numerical control. So that should be the title of the article. [[User:Isaac Rabinovitch|Isaac Rabinovitch]] ([[User talk:Isaac Rabinovitch|talk]]) 16:49, 16 March 2025 (UTC)

*'''Two comments''': 1) Both terms seem to be used (e.g., per [https://www.pcmag.com/encyclopedia/term/numerical-control this]), and Wikipedia prefers concise titles. 2)&nbsp;I thought "numerical control" was simply an alternative term for using [[numerical analysis]] in a [[control system]] of any sort, not just something to do with [[machining]] or 3D printing. [[Control theory]] is applied much more broadly than for machining, and numerical methods are commonly applied in control systems, e.g., using [[Sampling (signal processing)|sampling]], [[A/D conversion]] and [[digital signal processing]]. —⁠ ⁠[[User:BarrelProof|BarrelProof]] ([[User talk:BarrelProof|talk]]) 21:46, 16 March 2025 (UTC)

*'''Oppose''' - Back when computers had tape drives, you wouldn't think of using a computer to control a machine tool - NC tools had dedicated random logic that was much simpler than a programmable computer. --[[User:Wtshymanski|Wtshymanski]] ([[User talk:Wtshymanski|talk]]) 01:55, 17 March 2025 (UTC)

*:So you're saying that numerical control is not the same as ''computer'' numerical control. But the article treats them as the same. If you're right (and you do appear to know more about the topic than I do) than the article needs to be rewritten to make the difference clear. [[User:Isaac Rabinovitch|Isaac Rabinovitch]] ([[User talk:Isaac Rabinovitch|talk]]) 22:18, 17 March 2025 (UTC)

*::Wtshymanski, your claim is not borne out by our [[history of numerical control]] article. [[User:Srnec|Srnec]] ([[User talk:Srnec|talk]]) 20:05, 18 March 2025 (UTC)

**[[WP:SOURCES|Unreliable web site, known for user-supplied content.]] Imagine finding two incorrect Wikipedia articles on related topics - what are the odds? A talk page is not an article. I recall standing in a Dominion Bridge plant after they declared bankruptcy. Our company was slightly interested in buying an NC plate cutter they had (though I don't think there was a plan to use it as NC) - I flipped through the manuals and schematics, seeing page after page of TTL...and nary a CPU to be seen. Does our "history of numerical control" go back to the vacuum tube era, or does it just discuss the time since Bill Gates invented the IBM PC as a way to sell more copies of Microsoft Office? ---[[User:Wtshymanski|Wtshymanski]] ([[User talk:Wtshymanski|talk]]) 16:49, 20 March 2025 (UTC)

*:::I think @[[User:Wtshymanski|Wtshymanski]] makes a really important point. I still favor the move request (which I wrote in the first place) but it's true that NC and CNC are not the same thing, and the article needs to reflect that. The confusion comes from the fact that pretty much all NC is now CNC, but didn't used to be. [[User:Isaac Rabinovitch|Isaac Rabinovitch]] ([[User talk:Isaac Rabinovitch|talk]]) 20:17, 18 March 2025 (UTC)

* '''Support''' The original meaning of numerical control is an important one, and my first thought was to oppose this move, on that basis. However we also have an article at [[history of numerical control]]. Given that, I've no object to renaming this to follow the modern term of CNC instead. [[User:Andy Dingley|Andy Dingley]] ([[User talk:Andy Dingley|talk]]) 22:23, 17 March 2025 (UTC)

*'''Support''' per Andy Dingley. The current title is broader, but this article is mainly about CNC. [[User:Srnec|Srnec]] ([[User talk:Srnec|talk]]) 20:05, 18 March 2025 (UTC)

{{ping|Wtshymanski}} Our [[history of numerical control]] does go back to the vacuum tube era and describes machines using punch tape and magnetic tape drives. You wrote, {{tq|Back when computers had tape drives, you wouldn't think of using a computer to control a machine tool}}. Perhaps I do not understand your meaning.
