"Sure, hit me with the example :)"
It's very common to do secondary operations like 5 axis drilling, reaming and very limited milling on a manual knee mill with a tilting rotary table because many shops either don't have a 5 axis CNC or don't want to tie an extremely expensive machine up.It especially common to see this in many aerospace shops that also do sheet metal fabrication. See this link. They are one of the oldest job shops in Phoenix. http://dvelco.northstar-aerospace.com/ Check out the sheetmetal weldments. Lots of holes that are are done on compound angles. Also see the links page. Maybe Northstar Aerospace has an division in your area ? Weldments are very challenging to do. jon "jon banquer" wrote in message ... "Well, my instructors were both machining for a living for a long time before they started teaching this course, so they have a pretty good idea of what's useful for us I guess." I'll have more questions about your instructors after you have more of your time invested in this machining program. Also, after you have had awhile to get to know others in this newsgroup and have kicked around some of their ideas. "Sure, hit me with the example :)" It's very common to do secondary operations like 5 axis drilling, reaming and very limited milling on a manual knee mill with a tilting rotary table because many shops either don't have a 5 axis CNC or don't want to tie an extremely expensive machine up.It especially common to see this in many aerospace shops that also do sheet metal fabrication. Can you see where this would make sense ? "I think the point of making ours was just to get a few of our skills checked off, and to have a little tool we could use if we want/need to." Okay, but do you think that when you make a shop tool in class that it should not only build your machining skills but also be a shop tool that can be practical to use when you go to work in a machine shop ? If the shop tool takes too long to setup, in what I like to call the real world of the small machining job shop, is this a good shop tool to make if you have a choice in the matter ? :) You didn't think I was going to let you off the hook that easy did you ? LOL :) "I have enough to absorb right now, with working ahead in math and reading about metallurgy. Soon I'll be starting the lathe section in the textbook, and there's a lot of questions to work on with that." Yes, understood. I'm trying very hard to not overwhelm you. Let me know if it's too much. "Then I've got a couple more presentations coming up in communications class. :P" You certainly don't want my opinion on what I think of your "communications class" and how I would approach it. :) "I've met a couple of machinists that would take the time to explain things to me about machining even when I was just deburring. I hope I get to work with more like them." A couple of machinists in this newsgroup (not including myself, here) have already shown a willingness to spend time pointing out things that they feel are very helpful. Some of these posters are people I have a great deal of respect for and who, because of experience, are much better machinists than I am. I do, however, have other technical skills that I use to, shall we say, even up the odds to keep their egos in check. ;) "I don't much enjoy having to ask someone else if I can use their tools, and wasting time digging through the shop to find something - argh." Hmmm you and I might think alike here. Wait till you see what it's like "wasting time digging through the shop to find something" when the pressure is really on. Your "argh" might very well become something else more along the expletive lines and you might very well forget all about a recent hangover. :) "Cool, I'll look into making one of these. It would be handy to have." When your ready ask and I will give you more details... if you haven't figured it out on your own by then / already. ;) "When I get on the horizontal mill I'll worry about learning more about it. :) I've got enough on my plate right now." I hear ya ! See what I wrote above. "Lol, just like real life, then. Not everyone gets along. I guess it's just an unfortunate fact of life. You can learn something from everyone if you keep your ears (err, eyes in this case) open. You just have to learn to ignore the crap." IMO, the advice Bottlebob gave you is most excellent. Give some thought to following it, if you have not already reached your own conclusion. jon "chem" wrote in message ... Industry determines what we're taught, because they know what skills they want us to have when we're ready to join the workforce (or re-enter the workforce). Well, my instructors were both machining for a living for a long time before they started teaching this course, so they have a pretty good idea of what's useful for us I guess. jon banquer wrote: IMO, also very important to be able to do quickly. If you wish I can provide an aerospace example of why it is important and why a manual knee mill is often used to do this kind of work in many CNC machine shops. Sure, hit me with the example :) If you get a chance try and look at any commercial boring head so you can see how it is designed so that it can move short distances accurately. Does your school have something like a Bridgeport or a Criterion boring head that you can examine so that you can see how they have been designed to accomplish this task ? We have a few commercial boring heads around the shop, and I've seen how they work. I think the point of making ours was just to get a few of our skills checked off, and to have a little tool we could use if we want/need to. Perhaps before... depends on you and how much you can or want to absorb. :) I have enough to absorb right now, with working ahead in math and reading about metallurgy. Soon I'll be starting the lathe section in the textbook, and there's a lot of questions to work on with that. Then I've got a couple more presentations coming up in communications class. :P IMO you will find others, like I have, that will give you "the shirt off their back" when it comes to sharing their knowledge. After you have found others like this you may notice, like I have, that they all fit a pattern that others don't. I've met a couple of machinists that would take the time to explain things to me about machining even when I was just deburring. I hope I get to work with more like them. If you don't you will either have to buy them or spend your time hunting for the shop tools / asking to use someone else's. I never felt I had the time to do this as I wanted to use my time on other things. I also like knowing what my tools can do rather than being surprised by a tool that I don't know. All depends on what your comfortable with and willing to accept or not accept. I don't much enjoy having to ask someone else if I can use their tools, and wasting time digging through the shop to find something - argh. But I have absolutely no problem letting someone else use one of my tools as long as it finds its way back to my tool box when they're done with it. Not very complicated. It's all in the design and most designs suck because they don't have a precise enough adjustment to *easily* allow you to move in tenths. The concept of how to do this is similar to controlling movement of a boring head. The most complex thing you would need is a piece of spring steel. Yes, you use a dial indicator with it. Cool, I'll look into making one of these. It would be handy to have. "Most of the stuff about the horizontal mill... Well, I could understand most of the terminology, but I couldn't catch it all." Ask them directly in the newsgroup or find someone you can e-mail that you suspect / knows what they are doing and is good at explaining their thoughts. When I get on the horizontal mill I'll worry about learning more about it. :) I've got enough on my plate right now. Just a few of my observations over I think 5 or 6 years of posting he You might want to make sure before you do that your prepared to take the heat and / or watch the bad vibes go down as the fighting starts. At times the bad vibes will carry from thread to thread and the level of hate will know no limits. Lol, just like real life, then. Not everyone gets along. I guess it's just an unfortunate fact of life. You can learn something from everyone if you keep your ears (err, eyes in this case) open. You just have to learn to ignore the crap. You doing what I would call indexing with a rotary table. I have a lot of stuff I would like to convey to you about rotary tables. As you start to use them, and if your still interested, I will have more to say. :) Well, I guess I'll be starting with that today. I'll let you know how it goes, and when I get the bare basics down you can pass on some of your stuff to me. :) chem -- www.xanga.com/chemgurl |

LOL For the following - bear in mind here that I'm talking from the very limited knowledge I've picked up so far. I'm in no way trying to look like a know-it-all, and I don't know exactly why that boring head was chosen as one of our projects. While I understand where you're coming from, the skills we got for that project we using dovetail cutters, milling a through slot, drilling and reaming on the mill, tapping holes, making a gib to fit. That we got a tool to use out of it was a fringe benefit, but not the main purpose. I don't believe our skill level is up to making something of the same quality and design as the commercial boring heads. And in the "real world", hopefully we wouldn't be expected to have a commercial-quality boring head in our tool box. Now, having said that, is there a type of boring head somewhere in between the commercial type ones I've seen around the shop and the ones that we made? If there is one that would be within our skill levels, but with a quicker setup time, maybe it would have been more practical to use that design instead of the one that we did use, and I could bring it up with the instructors. Yes, understood. I'm trying very hard to not overwhelm you. Let me know if it's too much. Nope, not too much yet. :) You certainly don't want my opinion on what I think of your "communications class" and how I would approach it. :) I don't think many of the people in our course see the value of our communications course. But like I mentioned, our curriculum isn't developed randomly. The college meets with representatives from industry and finds out what skills they would like potential employees to possess. Our curriculum is developed based on that. When your ready ask and I will give you more details... if you haven't figured it out on your own by then / already. ;) Pass the details along anytime.

While we're on the subject of parallels - why are there holes through the middle of them like the ones below?

When I did die work we put bolts or pins thru the holes to keep the parallels standing upright so we could lay a die on them. You can also bolt them down to an angle plate to machine things on angles. I've also used them as steady rests for grinding or milling something long. Mount them with a shoulder bolt and a lock washer, adjust to maintain height to the end of the workpiece. You can also use them on the side of the mill vise for a stop. The list goes on..... g Bing |

I no longer see it as productive to answer any questions
that you may have in this newsgroup. If others can't be of help and / or you wish my opinion you may feel free to e- mail me. If this is not a viable alternative to you than I hope I have been helpful to you in someway. jon "chem" wrote in message ... jon banquer wrote: I'll have more questions about your instructors after you have more of your time invested in this machining program. Also, after you have had awhile to get to know others in this newsgroup and have kicked around some of their ideas. I'm not sure how many questions I could/should answer about my instructors. I try not to say too much about people on the internet without their knowledge. Things like that tend to come back and bite me in the ass. It's very common to do secondary operations like 5 axis drilling, reaming and very limited milling on a manual knee mill with a tilting rotary table because many shops either don't have a 5 axis CNC or don't want to tie an extremely expensive machine up.It especially common to see this in many aerospace shops that also do sheet metal fabrication. Can you see where this would make sense ? Makes sense. Okay, but do you think that when you make a shop tool in class that it should not only build your machining skills but also be a shop tool that can be practical to use when you go to work in a machine shop ? If the shop tool takes too long to setup, in what I like to call the real world of the small machining job shop, is this a good shop tool to make if you have a choice in the matter ? :) You didn't think I was going to let you off the hook that easy did you ? LOL For the following - bear in mind here that I'm talking from the very limited knowledge I've picked up so far. I'm in no way trying to look like a know-it-all, and I don't know exactly why that boring head was chosen as one of our projects. While I understand where you're coming from, the skills we got for that project we using dovetail cutters, milling a through slot, drilling and reaming on the mill, tapping holes, making a gib to fit. That we got a tool to use out of it was a fringe benefit, but not the main purpose. I don't believe our skill level is up to making something of the same quality and design as the commercial boring heads. And in the "real world", hopefully we wouldn't be expected to have a commercial-quality boring head in our tool box. Now, having said that, is there a type of boring head somewhere in between the commercial type ones I've seen around the shop and the ones that we made? If there is one that would be within our skill levels, but with a quicker setup time, maybe it would have been more practical to use that design instead of the one that we did use, and I could bring it up with the instructors. Yes, understood. I'm trying very hard to not overwhelm you. Let me know if it's too much. Nope, not too much yet. :) You certainly don't want my opinion on what I think of your "communications class" and how I would approach it. :) I don't think many of the people in our course see the value of our communications course. But like I mentioned, our curriculum isn't developed randomly. The college meets with representatives from industry and finds out what skills they would like potential employees to possess. Our curriculum is developed based on that. When your ready ask and I will give you more details... if you haven't figured it out on your own by then / already. ;) Pass the details along anytime. I can put them in the binder with my other projects, even if I'm not ready to make it right away. :) chem -- www.xanga.com/chemgurl |

Well, thanks for the help. I guess I said something to offend you or
something, but for the life of me I can't figure out what it was. chem jon banquer wrote: I no longer see it as productive to answer any questions that you may have in this newsgroup.

"Well, thanks for the help. I guess I said something to

You did nothing to offend me and I would have hoped I made this clear when I said in my previous post to you : "or you wish my opinion you may feel free to e-mail me." I don't see it as productive to put the time into answering and really thinking about what I believe needs to be said to you, based on the current environment (which you have correctly noted exists) in this newsgroup. jon "chem" wrote in message ...

Oh, find a moderated group then for Keyrists sake. BTW, machines.homeip.net on iRC is moderated. Muwahahaha. How did you like it when you logged in the other day? You didnt stay long. Bing |
