  • Problem-solving is what we do as machinists. I had two radii I needed to cut on a part, something I don't like to do. But I came up with a faster way to do this task that I want to share with you guys. I think you'll appreciate it, enjoy.

      You can also use NLP techniques to change those old 'triggers'...
      (We do it all the time, changing from one state to another... if you want to make one, all you have to do is remember the steps you chose to be your 'trigger'... and your 'emotional peak' is key, as well.)
      Another is,
      Change the way you perceive it by 'muting' it or shrink it...
      And make it ginormous and loud... and Blissful... of that which you want to be your experience in life...
      Just think about all those Blissful moments you can create by being free from those pesky limiting voices... (the 'mask' that looks and sounds like you, but it only limits and creates suffering; you'd be surprised who is behind that mask)...
      Towards more Blissful moments~!

    I worked for many years as a prototyping/research machinist for an aerospace R&D firm. I can't tell you how many times we'd have a "whiteboard engineering" session, and I'd then be asked at 11:00 if I can have something knocked out for the 1:00 AM meeting. Tricks like this are invaluable when it needs to happen "now if not sooner." It may not always yield perfect results, but in the R&D business, perfect is almost always the enemy of good.

    If you are planning to stay manual, look for a cross-slide rotary. This type of table mounts to your mill table just like anything else, but there is a built in cross slide on top of the rotary. You can mount your Kurt type vise on top of that. This allows you to turn a radius on one end of that short workpiece, move the cross slide over and cut the radius at the other end. You can keep this setup on the mill permanently. You will need a 6 inch riser too no doubt.

    To have 6 radiused parts made on a CNC mill plus 3-4 week lead time..if they needed adjustments
    It was the same cost, and wait time..You have solved both my prototype cost plus a long wait!
    I have approximately $1200.00 in the mill, tooling, clamps etc... I will have them completed by
    The end of the week, and now I can also prototype an actuator assembly with radiused ends!!

    That was a good tip. I have ALWAYS had access to a rotary table and of course now a CNC mill so I never had to do what you describe here but that being said for those that do not have access to either of the two afore mentioned machines this was an excellent way to achieve that radius. For the garage machinist with little to no fancy equipment you demonstrated a great way to achieve the goal.
    I served my tool and die making apprenticeship with Ford Motor Company over 53 years ago and always had good machines to work with. We even had a mill that had a rotary table built into the bed so you could move both X & Y but also circular. This of course would allow one to make complicated parts with many radiuses and straight cuts with one setup. That was back in the 60s. Of course as time went by we acquired NC and CNC machines including Mills, Lathes, and EDM machines so I never had to do what you demonstrated here but you know what the say, "You can't teach an old dog new tricks". Well that is crap. I am 75 and turned the handles all my life and now have a CNC mill in my garage but you have defiantly taught this old dog a new trick and for that I am grateful and quite frankly impressed to say the least. I am a firm believer in the KISS Principle, Keep It Simple Stupid!
    The world today is full of ignorant people and they haven't a clue as to what it takes to make parts for whatever and they don't realize what it takes to make something, anything. A lot goes into the setup and just holding parts to machine them is something that has to be learned. You have to be able to improvise and adapt to use the tools you have at hand. This is the sign of a good tradesman. Machine tools cost a lot and even the tool holders and end mills will run you into the thousands.
    Great job my friend.

      This is one thing I have an issue with the 3D printing community. Because you are drawing straight from CAD to CAM, they never learn how to make efficient designs, or ones that are easily end user serviceable. Many 3D printed designs are very difficult to translate to higher quality metal products, even through advanced casting techniques.

    This is a great idea! Never thought of it. I have a machine at home, an '81 Bridgeport. I don't want to invest in a seldom needed rotary table or a lathe for round work either. If you have a digital you can also do facets using a hole pattern movement with end mill. That is trigonometry for rise and run/ radius math stuff.

    I'm impressed with many of your attributes... with your humble but yet intelligent and informative teaching style. I learn better when an instructor has patience and is passionate about their work.
    I happen to bump into your channel by accident. I am a Designer/Machinist, in the past I dealt with many machinists that have a cocky attitude-- and that ignorance interfered with my creativity, and full imagination capacity. Now I work on on my own with no interference, which in turn allows me to make Ultra- Modern metal sculptures from begging to end, and I get way.... better results. I just called three Designers (one from MIT) and told them all about you, and your channel, we are all exited, because we concentrate on the explicit and implicit, to save time, money and aggregation, that allows the ability to exercise creative freedom, without any interference. On the technical aspect, you have incredible-well thoguht- out machining solutions, very intelligent approaches.

Did others opinions of you or your work influence your output? if that's the case, then you are week-willed. The concept of this video is interesting, yes, but its applications are slim. How many pieces will you be cutting that has a thru-hole conveniently placed in it? What if you have a small radius and a large piece? It's definitely not "WOW!!". You are no designer my friend. You are no machinist. Please reevaluate your life.

    That is a great idea. But the way I do it is I
    take a block of wood drill a hole the size of the pin then take a hack saw cut
    from the block of wood to the hole then put the pin in the hole put it in the
    vice and close the vice nice and tight then put it up close to the end mill and
    make sure they are square to each other once you are happy with every thing put
    the piece you want to shape on to the pin space it out the same way you did in
    the video on one side or the other once you are happy with that go ahead and cut
    it if I'm making one piece and it is a small part like in your video I use a
    pair of vice grips to hold it and pull it through the milling bit but if I'm
    making lots of them I will make a tool to hold on to it so my hands and finger's
    are no to close to the bit you can cut the full 180 degrees in one pass you can
    all so cut 360 degree circles to doing this.

    It's a useful trick, but setting up a rotary table is pretty straight forward for things like this, and will give far better results - and once you've learned the set-up shortcuts, it's probably just as quick.
    Also, you should never set Z zero with the knee handle removed or on the left...

      Also, not all brand new home machinists have access to a rotary table. We tend to get components as we can afford them.

    Did you ever try disengaging a rotary table and turning the part with your hand? Using a 4 flute end mill and NOT climb milling it works better than you would think. This can also be done by setting a vertical pin and hand feeding the part thru the rotation. Similar to what wood workers do with the band saw. Thoughts?

      I was thinking something similar. I'm just an apprentice now buy seems like putting a pin in and rotating the part is easiest way. I use the cnc mill for my radii and that's how it cuts. With the side of the end mill.

    All that time you save by not turning off the spindle is how I cut off the end of my right index finger. It not worth a finger or hand guys turn the spindle off whenever you reposition the part in the vise. You might think your smarter than the machine and it won't happen to me but believe me that end mill will eventually bite you and it doesn't care who you are or how smart you think you are!!!!

      +Eric Horton Like I said it's not luck, it's skill, paying attention, making safe and repeatable routines, not getting sloppy etc.
      some operations you HAVE to interact with a rotating part, the difference is having the skill and experience to know what you're doing, in the safest manner possible, while still getting the job done.
      I'm not knocking you, just saying you can safely interact with the tools/parts with the machine running with the proper knowhow.

    • @clayz1
      @clayz1 7 лет назад

      The multiple facet thing is good. So long as your part is small enough to fit the vise. And so long as you have a pin hole. If not you can take another approach, which is the equivalent of using your DRO to do half of a bolt circle and a lot of holes, but with an endmill, not a drill. Ive used this technique for rounding machine keys that will be blocked into a shaft. Works pretty good.

    • @shawncrocker7037
      @shawncrocker7037 7 лет назад

      Scotty Mac 22 yes I would prefer to think outside the box and develop a more efficient way to setup a rotary table. it is a cool idea but I feel the tolerances for a situation to allow this technique to be used are too tight.

    • @KC9UDX
      @KC9UDX 7 лет назад +2

      Scotty Mac 22 Yep, all it takes is a slip fit pinhole in a plate, and a big lever (crescent wrench and pipe?) attached to the end of the part opposite the radius. The technique in the video is interesting, but I don't think I'd ever do it that way.
      I may soon take on a job where I have to do this (machine outside diameter of round part bigger than machine travel) so I guess I'll have to make a video.

For instance, a welder I work with left his die grinder with a cut off disc on it in his lap and reached over to grab something and zipped his knob. We call him half shaft now. It wasn't actually an amputation, just a cut but still.
