History of Machine Tools
I am preparing a research assignment for my students on this subject.
Looking for suggestions as to names which might be used as search terms or links to sites that would be appropriate. Also, I am not remembering the names that were involved in the creation of the first NC machines back in the late forties/early fifties. I know that the info is back in my head somewhere but it is not coming forward. Help would be appreciated! I don't want togfive the kids everything obviously but I do need to give them enough to get started It is tough to do research on a subject when you don't know enough about it to even know what questions to ask. Thanks for your help! Errol Groff Instructor, Machine Tool Department H.H.

Hardinge, Cataract. Seneca Falls, Barnes. Pittler. Pratt and Whitney. The earliest NC machine I saw was a Csip horizontal overarm jig borer, running off of paper tape. I think it was 50s vintage.

Hate to mention this, but we received word last week that G&L's foundry is
closing permanently. There is some possibility that our foundry would get some of the work. I work at the former Cincinnati Milling Machine Co. (or Milacron) foundry, now known as Cast-Fab Technologies, Inc. If you'd like to see some historical photos of the machine tool industry, please go to: http://memory.loc.gov/ Click on the search link and type into the search bar "Milling machines and machine castings" WITH the quotes. You will get a hit for a number of photos of the foundry in 1942. The foundry is not identified, but it is the Cincinnati Milling Machine Co. foundry. The reason it was not identified is because it was early on during WW2 and there were fears that sabotage or bombing would take place so the foundry name was kept secret. Next week the auctioneers will be at the machine shop and everything must go. The foundry is the only part left still producing. Of course we use electric furnaces instead of the cupolas and furan sand instead of green sand but the building itself is still the same. Mark Fields "Ned Simmons" wrote in message ...

that topic could be covered in another class. Maybe make
it part of the english curriculum. IMO, this would be the right approach. Those interested in machining attend a english class that has been tailored to their curriculum. Just as the math classes should be oriented to machining. Again, agreed. Wish I had a choice like this when I was in high school.

History of Machine Tools
Hey Bob...
When I first stood in front of a Bridgeport mill I thought it was just built by a big company. I didn't realize it was designed and built by a person like you or me. It's nice to believe a machinist can build something as cool as a milling machine. You get that feel by reading the history of inventions and their origins. Also, history gives you a prospective of where the technology is going in the future. By viewing the origin of how an invention was conceived, then where it has come today, it can help us find the direction it will go in the future. If you have an idea where things will go in the future you can make plans to your advantage. *Smile Regards, Stan- |

As far as it goes, I wouldn't disagree. But studying the background and history of one's field is one mark of a professional, in the old sense of the word. I'd like to think that people getting into the field as a career, rather than just as a job, would be interested in how their industry got where it is today. If the students aren't curious about it, then there isn't much point in forcing it upon them. But I believe quite a few would be interested. I used to lecture on dimensional metrology, often to young people who were new to the field, and I remember a lot of questions about the background of the technology. They seemed interested in the way things were done in "the old days," mostly because they were amazed at how one could measure to such extreme accuracies without the benefits of electronic technology. -- Ed Huntress (remove "3" from email address for email reply) |

The role of the machine tool in the general shift toward standardized parts and procedures, the advent of "scientific management", Taylorism, the rationalization movement. Backlash against machinery/technology in general, Luddites. Who gained, who lost, as machine tools/manufacturing facilities became more advanced and capable? A thorough treatment of these topics would be beyond the scope of the assignment, but some students might want to explore how machine tools developed in a larger context. |

Though I agree with the value of learning how to use the tools effectively I also feel that anyone who doesn't wonder about those who came up with the tools is sadly lacking, and would benefit greatly from a study of the self discipline that those great men operated under. Any really well rounded machinist must hold men like Whitworth, Maudslay and Colt in awe, and their workmanship improves as they realize they are following in the footsteps of such great human beings. Also; Wilkinson, (HBM) Whitney (Milling machine), and many others. I believe we become a little like our heros when we study their lives, and those who discovered how to turn tool paths into data a machine can follow automatically are certainly worthy of the same study. The "drones" are the ones who don't care about such things, in my opinion. |

I don't read this as a lie at all. It's all in how you read things. I
believe they are telling the history of G&L, not the history of machine tools. Therefore they are stating they built "THEIR" first NC machine tool in 1955.

Errol: The history of Machine tools seems like it would be a interesting subject, BUT... If I were in a limited time machine shop class for the purpose of increasing my skill level with the hope of becoming an employable entry level machinist, I think *I'd* (and probably prospective shop owners might also) be more interested in just HOW to edge find or indicator sweep my parts rather than knowing WHO designed the first edge finder, or indicator, or CNC. Don't take this wrong, I don't mean to be overly critical here, I'm just giving you a view from a job-shop productivity standpoint. If I were interviewing two prospective entry level apprentices I'd be more inclined to hire the one that showed a knowledge of the practical application of theory over one that had historical knowledge. Though I agree with the value of learning how to use the tools effectively I also feel that anyone who doesn't wonder about those who came up with the tools is sadly lacking, and would benefit greatly from a study of the self discipline that those great men operated under. Any really well rounded machinist must hold men like Whitworth, Maudslay and Colt in awe, and their workmanship improves as they realize they are following in the footsteps of such great human beings. Also; Wilkinson, (HBM) Whitney (Milling machine), and many others. I believe we become a little like our heros when we study their lives, and those who discovered how to turn tool paths into data a machine can follow automatically are certainly worthy of the same study. The "drones" are the ones who don't care about such things, in my opinion. |
History of Machine Tools
Hi again Ed..
I guess I have brand 'X.' There is no Gold name on it. *shucks! Also, I would be interested in which articles you wrote. Would you please list them for me? You see... You are part of the history as well. *Smile Best regards, Stanley Dornfeld "Ed Huntress" wrote in message . .. "Stanley Dornfeld" wrote in message ... I guess I was pretty lucky! My copy is also a hard bound. Boy! I'm really feeling too cool. *S, Really! Thanks for the info. Whose name is stamped in gold on the lower right corner of the cover? If there's no name, the publisher may have made another run that we editors didn't know about, for key advertisers or something. The 20 copies (roughly) were for the editorial and publishing staffs.

... Hi again Ed.. I guess I have brand 'X.' There is no Gold name on it. *shucks! Aha. Then there were other copies hard-bound, besides the special run made for those of us who worked on it. They probably were presentation issues for advertisers. Andy Ashburn, who was the Editor then, may know. I'll ask him when I get to it. Also, I would be interested in which articles you wrote. Would you please list them for me? I'd be interested, too. You're assuming my memory is good for sorting out which items I wrote in an issue written 26 years ago. That's a lot of assumption. g I was trying to blend my style with the overall style of the book, so it's a little hard to remember which ones I actually wrote -- especially since I had a hand in editing most of the book, and we tend to forget what we actually wrote versus what we just edited. I'll take a look this evening and try to remember. I can tell you this, though: Sometime in the mid-'90s, the current owners of American Machinist (Penton Publishing) ran a special issue that, essentially, was a rip of the 100th Anniversary Issue, which had been published by McGraw-Hill, the original owners. They just lifted the pieces verbatim -- including two or three of mine -- without acknowledgment of where they came from or who wrote them. Then they put a new byline (sort of) on them, saying "edited by," and listing some member of their current staff. They own the material and there was nothing explicitly unethical about it. But it really grated the hell out of those of us who spent a year of our lives researching and writing it. You see... You are part of the history as well. *Smile I realize that every time I look in the mirror... -- Ed Huntress (remove "3" from email address for email reply) |

Looking for suggestions as to names which might be used as search terms or links to sites that would be appropriate. Also, I am not remembering the names that were involved in the creation of the first NC machines back in the late forties/early fifties. I know that the info is back in my head somewhere but it is not coming forward. Help would be appreciated! I believe the first Numerically controlled machine tool was developed as a joint venture of the Devlieg machine tool company and the Massachusetts institute of technology (M.I.T.). I don't want togfive the kids everything obviously but I do need to give them enough to get started It is tough to do research on a subject when you don't know enough about it to even know what questions to ask.

Read "Tools For The Job" by LTC Rolt. Superb book, and Tom Rolt was also a pioneer in the preservation of industrial archaeology. Names to conjure with are "Watt & Boulton" "Bramah", "Whitworth", various US gunsmiths, and the Norton grinding wheel company. The RAC Cadillac re-assembly trial is worth studying too. -- Die Gotterspammerung - Junkmail of the Gods |
