== DIY CNC ==

Hi, have you guys looked at http://www.cnczone.com  Tons of people are making their own CNC machines using recycled technology. http://www.linuxcnc.org is an amazing open source Machine Control Program that lets you control almost anything. It kind of changes the social impact when thousands of people have access to this technology rather than it being only in the hands of people who have access to big gobs of money. I run my own business and use a CNC machine that I made. It only cost me less than two thousand dollars because I made it myself. Other people have made them for even less from all recycled parts and are using them to cottage manufacture things.  <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/199.44.20.63|199.44.20.63]] ([[User talk:199.44.20.63|talk]]) 21:55, 13 April 2009 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

:Quite right. It is interesting to wonder where we are headed in coming decades. Things don't always turn out to have developed exactly as yesterday's futurism predicted, but they sure don't stay the same, either. [[User:Three-quarter-ten|—&nbsp;¾-10]] 23:16, 13 April 2009 (UTC)

:: The Wikipedia [[EMC]] disambig page links to this article, but when I looked at this article earlier today, it never mentioned EMC.
:: I see that EMC, one of the links you mentioned, and a link to another open-source CNC software tool, were once in the article, but were (accidentally?) deleted[http://en.wikipedia.org/w/index.php?title=Numerical_control&diff=278515743&oldid=277568449].

While the proliferation of small CNC as noted at www.cnczone.com is minor in terms of economic impact, the numbers of people involved is becoming significant.  Furthermore, it probably deserves more attention within Wikipedia simply because the orientation and demographic of Wikipedia users matches well with small CNC.  People who buy $400,000 6 axis mills do not research their investment at Wikipedia.  Small scale CNC people do.  Note I'm referring to this as small scale CNC, not DIY CNC.  I feel strongly that the turnkey offerings of companies like Sherline and Tormach, while not homebuilt, do represent the same architecture (PC Controlled) and the same community of users.  I plan on adding a bit on the evolution of this aspect of CNC.

I have removed the short comment at the end of section '''Today''' about DIY CNC, then added a section '''DIY, Hobby, and Personal CNC''' which details the evolution of small CNC.  The original reference to EMC and open source has been moved into the new section.  The reference to MyNC has been removed.  The MyNC link seemed to be a project of a single individual and without much following or impact on the evolution of CNC.  I have also removed the reference to www.cnczone.com.  While CNCZone is important to the community of hobby and personal CNC, it's not a reasonable REF since it is a major site with dozens of forums and thousands of messages.  If there were an overview article or some specific reference within CNCZone, that would be another matter, but in the context of the article it would be better as a link than a reference.--[[User:LifelongEngineer|LifelongEngineer]] ([[User talk:LifelongEngineer|talk]]) 02:32, 30 September 2009 (UTC)

Sorry, I frankly do not inderstand what topics are being didcussed here.NC as an adjective? This is an exactly defined technical term, to me you're splitting hairs and avoiding questioning CNC versus DNC technology; meaning, to me, running programs on a machine from a separately connected computer which hosts editing software and sends only G/MS/T information,typically in a serial port connection. Related, there is no mention of how most CNC machinery typically includes machine-specific SOFTWARE ROUTINES AS NECESSARY TO DEAL WITH, FOR EXAMPLE, tool changes, tool offsets,and the 'BACKLASH' mentioned. Sorry for the inadvertant capslock.. One major issue not mentioned is the use of box ways versus linear guides. Machinists and shop owners appear to have attitudes, preconceptions, and ego involved, and it's a favorite subject for some salespeople to bring up. The backlash assumption applies to machines using traditional acme-threaded leadscrews, something which may may not apply to newer ballscrew machines. And there's no discussion of how, particularyin cnc lathes, manufacturers also supply options for non 'cut time' operations such as feeding or measuring operations. These can very significantly affect throughput and geometric accuracy.  Then, the final missing issue is probing. And a quite seriously presumputous note about x86 basedindustrial computers; The sl20 shown has a 16/32 bit motorola processor,  zero wait state memory and a history of damage not from electromagnetic fields, but fork trucks and lightning <ref></ref>touching connected RS 232 wires. I'm not trying to be negative here but to provide critical reasoning, sorry my tone comes over this way.

== Returning to the topic of the social impact of automation ==
It was discussed on this talk page a while back (see [[Talk:Numerical control/Archive 1#Recent cleanup was well-founded (drat!) but article development continues]]). Recently I was motivated to coalesce some info at the article "[[automation]]" that addresses the larger context (automation in general, not just NC/CNC). So I'll find a sensible way to point from this article to that discussion for readers who want more info on the topic. [[User:Three-quarter-ten|—&nbsp;¾-10]] 02:23, 27 September 2010 (UTC)

== computer numerical controlled ==

Is this form (computer numerical controlled) correct?
It sounds awkward to me.
Shouldn't the original form (computer numerical control) be kept?
"Computer numerical control" is a noun (not just a noun, but can be considered as one complex noun), but, when turning it into an adjective, shouldn't it become "computer numerically controlled" if one REALLY wants to use an adjective?
The unaltered form (computer numerical control) sounds better to me. Am I wrong?  <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/89.122.248.141|89.122.248.141]] ([[User talk:89.122.248.141|talk]]) 15:18, 26 January 2011 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

:You're not wrong; in fact, I agree that you're right on all counts regarding what sounds better. The only asterisk to be tacked on is just that there is no "correct" and "incorrect" in the sense that you're probably expecting to find; [[natural language]] has its own well-rounded [[text corpus|corpus]] ([[wikt:instantiate#Verb|instantiating]] many options) despite any [[linguistic prescription|prescriptions]] that would try to guide it. We can edit this article to suit what you described, but we can't count on that lasting as new contributors come along, and we definitely shouldn't pick on them or tell them they're "wrong" for using the awkward versions. In natural usage people say/write all of the above, including the awkward ones—when they're even expanding "CNC" at all (which the initiated [those who know the subject] hardly ever do). The biggest place where the awkwardness-of-the-expanded-form question arises is in expository language (such as journalism, or this encyclopedia article) when the authors try to apply the usual convention of expanding "CNC" right at the spot of first mention, which is typical with abbreviations and acronyms in such language. Linguistically, there are several things going on at once (multivariate nature at work). The entire phrase, when used in an attributive (adjectival) position, can be treated by the brain as an invariable unit, as you pointed out (e.g., "computer numerical control machine tools" = "CNC machine tools" = no [[inflection]] needed on either), or as a phrase that requires inflection to its various component words—''but'' there's no universally agreed [[natural language|natural]] way to do it ("computer numerical controlled"?  "computer numerically controlled"?). It seems to me that the brain wants to do ''something'' with "computer" inflectionally, but can hardly decide what. ''Computed'' (as is done in "computed tomography")? ''Computerized''? ''Computerizedly''? (The latter works but violates English idiom, which is to say, "doesn't work"). The brain spins its wheels and stumbles along. It seems to me that often many brains simply settle for treating the expanded noun phrase as mostly invariable—at least ''internally'' invariable—but they'll tack an ''-ed'' inflection on the end because it just "feels right" to say "...controlled [noun]" as opposed to "...control [noun]". Thus we get the one whose awkward feel you pointed out. Now, let's backtrack: "Numerical control" was the earliest of the terms, and it was coined as a noun (=noun phrase) from adj+noun. When you wanted to turn it into a [[noun adjunct]] (that is, a noun used adjectivally, that is, an attributive noun), you naturally inflected "numerical" (adjective) to "numerically" (adverb) to yield "numerically controlled machine tool" (adv+adj[pp-used-adj'ly]+noun). But then people modified the term "numerical control" in [[retronym]]ous fashion to yield "''computer'' numerical control". They also could have naturally chosen to call it "computed numerical control or "computerized numerical control", but they didn't. It hardly matters, though, because with all three of those (noun sense) options, you have no natural-sounding move to make, in terms of inflecting the phrase internally, when it comes time to use the noun as a noun adjunct (that is, to use it attributively). And the people who coined the noun sense didn't think of that ahead of time. The answer, as usual in natural language, is that "you're not supposed to think about it that hard"—you're supposed to spit it out, feel uncomfortable for a split second, and move on. People who are familiar with the ''meaning'' of the term use the abbreviation anyway—not the expansion—and in that case, "CNC" (noun sense) and "CNC" (adjectival sense, that is, noun adjunct sense) are inflectionally identical, so it's a non-issue entirely. As I said, the stumbling over the expanded form is usually only a problem in expository language (most especially expository writing)—that's where it ends up being dealt with or dwelled upon. And no matter what you [[linguistic prescription|prescribe]] in that context, natural language will not consistently follow the "rule". And the great thing is that that doesn't matter—natural language doesn't have to care. "If you catch my meaning, then the language did its job." Everything else editing-wise is just ignorance of linguistic science. Unfortunately for those looking for a simple answer, there is no answer to the question of "but which way is ''correct''?" where "correct" is defined in the sense of [[traditional grammar]], because traditional grammar misunderstands linguistic reality. The only "answer" is that the definition of "correct" doesn't apply. Hope this is found interesting. —&nbsp;[[User:Three-quarter-ten|¾-10]] 20:51, 26 January 2011 (UTC)

:: For the record, I removed the ''-ed'', not because it can be called "incorrect" so much as "deprecated by those in the industry". Which is more or less what [http://en.wikipedia.org/w/index.php?title=Numerical_control&diff=383559720&oldid=382868802 this diff] was also getting at (preferred usage), plus or minus the notion of "correct". —&nbsp;[[User:Three-quarter-ten|¾-10]] 23:31, 26 January 2011 (UTC)
::Neither is correct per ISO.
::ISO 2806 provides the international technical definitions.

::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.

"Enter MIT

: But why? I guess you mean that [[WP:NPOV]] extends so far as not calling a task daunting. If that's basically what you mean, I think you're misinterpreting the NPOV concept. The article isn't "biased against" the task of incorporating a feedback loop (not calling it harder than it really was). It's just acknowledging the reality (the malice of inanimate objects, as [[M. R. James]] might have called it). If you removed this way of phrasing, the next problem you would have is that the average reader would have no concept of whether a small problem or a large problem was being faced (being naturally unknowledgeable about the topic).

:: I think the problem is that this article feels too dramatic, which (in my mind at least) lowers the overall credibility of the article.  I don't know exactly how to classify it, but the article feels a little more like an essay, or a school report, then an entry you would see in an encyclopedia.  And perhaps the word 'large' would be a synonymous but less dramatic substitute for 'daunting?'  <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/67.182.140.4|67.182.140.4]] ([[User talk:67.182.140.4|talk]]) 23:50, 17 April 2011 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

::: I don't know, this view doesn't resonate with me. It's not inappropriate for an encyclopedia to call a task daunting if it ''is'' in fact daunting. There are many examples in engineering. The biggest ones, of course, are things like the Mercury and Apollo NASA programs, or the Hoover Dam, or the Manhattan Project; but even the countless smaller and less famous ones were daunting for the people working on them. For example, the program to develop the 747 was a hair-raising gamble for Boeing, and there were a lot of sleepless nights for the engineers and machinists involved. The effort to write the [[OED]] was daunting. There are others who share the [[register (sociolinguistics)|register]] aversion, but given that it's artifactual (coming from enculturation rather than inherent in reality), I think it's best to move beyond it and just be completely honest in Wikipedia articles, and call a spade a spade. This register aversion always makes me think of the scene in the Wizard of Oz film where the wizard yells to the visitors to pay no attention to the man behind the curtain. He's insecurely trying to hide reality from them because it won't be as impressive as his puffed-up pretense. But the attempt is futile, because it assumes that the visitors are dumb enough to fall for it. Whereas they're actually smart enough to trust their own eyes. I think here in the internet era, where overt cynicism and iconoclasm have now been a part of our culture for a long while, and many readers have plenty of intelligence (if not knowledge of the specific topic they came to read about), most Wikipedia readers would rather just hear the truth via "le mot juste" rather than be condescended to by the wizard trying to put on airs. They actually find it ''more'' credible to hear the straight dope than to know that the tone of the phrasing is going to have to be discounted as a stylized convention (which is actually a kind of institutionalized dishonesty in a way—a lack of credibility in its own right). I guess what I'm trying to say (maybe not succeeding too well) is that this register aversion feels to me like Bowdler's attitude toward Shakespeare. Although he didn't know it, the attitude was never as necessary as he thought, because, contrary to his belief, the audience "can handle the truth". And when people read [[EULA]]s or website terms-&-conditions, they actually find it refreshing to find "normal people's register" as opposed to fossilized or evasive legalese (which they know darn well is ''not'' to be trusted). —&nbsp;[[User:Three-quarter-ten|¾-10]] 02:50, 18 April 2011 (UTC)

==Content from merge==
I recently redirected the [[numerics]] into this article, since all of its content was about numerical control and it didn't clarify in its lede how it could be a different subject.  In the stub, though, there was a paragraph that seemed from a cursory glance to be worthy of including here.  I'm just not sure where it would go.
<blockquote>The PCs that are used in industrial automation are usually an industrialized version of the [[x86]] family of computers. The main difference between consumer electronics and industrial electronics is that the industrial electronics can tolerate sub-zero temperatures and is designed to withstand dusty and electromagnetically noisy environment. For example, metallic dust can [[short-circuit]] electric circuits, which in turn can literally destroy the electrical circuits. Industrial electronics is designed to keep the dust out of the chassis. The electrical noise, which is mostly generated by  electrical motors, is dealt with by using optical cables instead of electrical ones or the electrical data communication (see:[[bus (computing)]]) cabling is well shielded ([[electromagnetic shielding]], [[Faraday Cage]]).</blockquote>

* '''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.

*'''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.
