VIDEO of cutting a thread on 4th axis of my Bridgeport Interact CNCmill with LinuxCNC
My guy asked me to cut a 1mm pitch thread on a custom shaft.
I could not do it on my lathe, so I finally bit the bullet and wrote a subroutine to do threading with my 4th axis rotary table. I use a 60 degree chamfering end mill. Now I can cut any thread, any pitch, right or left handed, and if the thread is very coarse, the subroutine does it in several passes. http://www.youtube.com/watch?v=JMENnIJrl9Y I am afraid that it does not create a 100% correct thread geometry, but I hope that I can do enough things with it to be useful with some adjustments to diameter. i |

Nice - to bad you can't use a hob ? I think that what thread cutters
are or Cob... They have cutters a foot long and 6" in diameter - coated and all - here in Lufkin - the foundry at Lufkin Industries has to do it all. Massive gears and massive bolts and nuts. The traditional donkey that pumps out oil is twice as long as those made by Lufkin. Their custom way saves space and when in buildings (hiding the pump) it becomes important.

Yes, to do it properly, I would need to orient the rotary table at angle to axis X. Too difficult for me to do it. I will mess with making threads to see how geometry affects fit and how I can compensate by fudging the diameter. i The traditional donkey that pumps out oil is twice as long as those made by Lufkin.

Hey, Jon, knock it off. I saw what he did with his Bridgeport. This guy looked deeply into what Bridgeport had done, and what was possible with some modern components and his own programming skills, and did something that would have amazed any of the commercial CNC retrofit companies I've visited and interviewed. Furthermore, he's gone from zero to a pretty good speed on learning how to machine parts. He takes his own path -- he seems to be as interested in the creative aspects of the work as in learning the conventional wisdom. He's put a lot of work into it and he's tenacious as hell. He's paid his dues, but not to prepare for some conventional machining job. He's doing his own thing and he's had some successes. Unlike many others, he's more of an inventor than a follower, and he's not afraid to fail. That's not to knock conventional training. It's just different; much rarer; and, to me, very interesting and impressive. So lighten up on him. He catches some very unfair flak. I've never seen him tell anyone that he knows how to do something, and they don't. He's just doing it his way. -- Ed Huntress |

I've always appreciated reading your metalworking related posts, Ed.. and
I've read quite a few of the OT posts too, I just don't respond knowing how wasteful it would be of my time. Your comments regarding the public's and potential buyers' perceptions of the little black rifle were right on target, IMO.. for example. I definitely noticed when you were gone, and was beginning to believe you'd just moved on to something more worthwhile. I've seen it happen with so many good contributors here that it's depressing. There are some very good forums such as Chaski where it's all-on-topic, all the time. -- WB .......... "Ed Huntress" wrote in message ...

Hey, Jon, knock it off. I saw what he did with his Bridgeport. This guy looked deeply into what Bridgeport had done, and what was possible with some modern components and his own programming skills, and did something that would have amazed any of the commercial CNC retrofit companies I've visited and interviewed. Furthermore, he's gone from zero to a pretty good speed on learning how to machine parts. He takes his own path -- he seems to be as interested in the creative aspects of the work as in learning the conventional wisdom. He's put a lot of work into it and he's tenacious as hell. He's paid his dues, but not to prepare for some conventional machining job. He's doing his own thing and he's had some successes. Unlike many others, he's more of an inventor than a follower, and he's not afraid to fail. That's not to knock conventional training. It's just different; much rarer; and, to me, very interesting and impressive. So lighten up on him. He catches some very unfair flak. I've never seen him tell anyone that he knows how to do something, and they don't. He's just doing it his way. Yeah Ed, I appreciate a lot of the encouragement that I see. I mean I come in here mainly for the electrical/plumbing/HVAC aspect, but still... You now, this back and forth with the insults almost takes on a comedy at the improv aspect, and some of the people here just can't seem to shake rivalries caused by insults in previous posts. But sadly, I honestly don't think it will do any good telling anyone here to act like grown-ups, but then again, I understand somebody's got to at least try. |

This guy looked deeply into what Bridgeport had done, and what was possible with some modern components and his own programming skills, and did something that would have amazed any of the commercial CNC retrofit companies I've visited and interviewed. Thanks, Ed. As of now, this Bridgeport has three major enhancements that I added, that improved on what it could do originaly. 1. Spindle encoder lets me do rigid tapping. I have a small lathe chuck that can be mounted in the spindle, and I hope one day to work a bit on making this work as a poor man's CNC lathe. 2. 4th axis based on a rotary table. It uses a resolver instead of more modern encoders, but fortunately Jon Elson had a nice resolver to encoder converter board. 3. The knee is fully motorized with a servo motor, making it an additional "axis" and enhancing my work envelope. I have not, as of yet, added home and limit switches, so it is not as safe as it should be. i |

Your comments regarding the public's and potential buyers' perceptions of the little black rifle were right on target, IMO.. for example. I definitely noticed when you were gone, and was beginning to believe you'd just moved on to something more worthwhile. I've seen it happen with so many good contributors here that it's depressing. There are some very good forums such as Chaski where it's all-on-topic, all the time. Thanks for your kind comments, Bill. Before I go, there's something I've wanted to leave here that I think some machining hobbyists can make use of. I met Dick Moore and interviewed his son Wayne, and Dick's work and writing was a huge influence on my hobby interest. He wrote a book in 1955, _Holes, Contours and Surfaces_, which explains how extraordianry accuracy was achieved before CNC and all of the closed-loop compensation we have today. I'll post a link to it below. Moore's son Wayne is famous for _The Foundations of Mechanical Accuracy_ (1970). It's also a great book and is available in reprint. The first book is about how the work is done; the Foundations is about how Moore built the machines that lifted us out of the very early era into the pre-CNC Jig Borer and Jig Grinder era. It's worth seeing just for the outstanding photography. LIFE magazine had just collapsed and Moore got one of their laid-off photographers. The work shows how black & white photography can be done, and it beautifully illustrates many of Moore's principles, including his insightful work on self-checking gages and making ultra-accurate leadscrews. I used to watch his scrapers achieve 20 microinch flatness, corner-to-corner, on the Moore measuring machines. It was amazing. That's my interest in this hobby, particularly in how things were done in toolmaking and gage-making before Moore. I've read three of his earlier books that aren't even listed in the Library of Congress, probably because Moore Special Tool self-published them. They may be gone but we had them at McGraw-Hill's library several decades ago. One was on the design and operation of the jig borer; a second on the jig grinder; and the third was a predecessor to the book linked below, _Precision Hole Location_ (1946) This is not like the old Colvin and Stanley books, which were about general machining. This is about the bleeding edge of accuracy. And keep in mind that most tooling work before CNC was drill jigs. The extreme examples -- master jigs for clock and watch plates -- required +/- 50 microinch accuracy. They could do it in 1920 but it was very slow (I have three custom faceplates and two sets of toolmaker's buttons, which were used for that work). When Moore got involved in the 1930s, the focus switched to making machine tools that would do it on an every-day basis, and to machining contours to the same degree of accuracy: http://babel.hathitrust.org/cgi/pt?i...view=1up;num=7 So, enjoy.

What kill files amount to in your case are the only way you can deal with those in this newsgroup who refuse to spoon feed you and coddle you. Your kill file allows you to not have to deal with those who call you out on your frequent false claims, your ridiculous naivety and your refusal to pay your metalworking and welding dues. Kill files are for pussies and you most certainly are one just like your hero Mark Wieber. An example of one of your false claims is you comparing your actions to what Aaron Swartz did. That you attempted to compare yourself to Aaron Swartz shows how ****ed in the head you truly are. So does your constant bragging about how cheap you buy stuff. The later shows where you place the majority of your focus rather than working on really building metalworking or welding skills. |

He's not like that other mook who kept asking how to do stuff, then insisted telling us we didn't know what we were doing, and on his doing it in the most dangerous and stupid ways possible. Lloyd Sponenburgh, one can't learn to be a decent machinist if they can't learn to develop the skills to think their way out of difficult situations on their own. |
