    What kind of EDM should I use?

    I think you are really minimizing the cost of 3R tooling. Hideously expensive is the understatement of the week!! But it's darn repeatable and fun to work with if you can swallow the price. But back to the question at hand. This could be completed with either sinker or wire EDM. You would...

    Machining Teflon, need some help on this VooDoo material!

    If the material is exhibiting a cold creep condition it may be changing shape after the machining process. Talk to a materials specialist and they may be able to describe this condition to you.

    CNC, MDI a 'helix bore'

    I would think you could post it in Catia and just look at the code. It has to be in the correct format. Therefore just copy it and modify and use as necessary. Another way to accomplish this is to have a program written to make a 1 inch helix. Use cutter comp to comp your tool on. You can...

    Maximum Contact Stress To Prevent Clamp Marks

    You are assuming that if you calculate the Hertzian stress and then back that out to a torque value for the clamp that the ham fisted operator will torque the clamp to your spec's. Why not just add a soft copper shim between the round bar and the v-block? The copper will deflect and the round...

    Tapping titanium

    Google "tapping titanium" There is a boat load of info out there...... Also, consult your favorite local tooling rep. There are some amazing taps out there for this material. You are looking for additional relief in the flute compared to a 'regular' tap. You WILL pay extra for taps specific...

    Cavity Mill _ corner control slowdown help!!

    Well, in that case I can't help you a bit.... But, here's something to think about. Is UG primarily a CAD package or a CAM package??? Me thinks its a CAD package. That being said, the functionality of any CAM add on should be an interesting proposition indeed. Good Luck!!!

    Cavity Mill _ corner control slowdown help!!

    Kyleb77, What is Cavity Mill? Is it a feature in a CAM software package?? If so, which program.

    Cavity Mill _ corner control slowdown help!!

    Are you using a CAM software package?? Many CAM programs have some feature that will accomplish this for you. If you are writing your own code by hand you could do something like this: G1X8.F200. G1X8.5F40. G3X9.0Y0.5I8.5Y0.5F40. G1Y1.0F40. G1Y8.0F200. G1Y8.5F40. G2X8.5Y9.0I8.5J8.5F40...

    cnc machines

    Well, I could remove more material using a 1910 Bridgeport that the latest Makino high speed machining center if I were using good technique on the Bridgeport and poor technique on the CNC. What I am saying is that it is not just machine capability, there are other factors that are vital to...

    Tapping Question

    (1 in) / (11.5 thd) = 0.086957 in/thd (0.086957 in/thd) / (0.03937 in/mm) = 2.2087 mm/thd lead. Just use 2.2087 mm as your pitch in your tapping cycle.

    Problems with transfer press

    Try McMaster-Carr page #2453 ball nose spring plungers. If you install these in your strippers they break the oil seal on the material and prevent sticking.

    PTFE machinging properties

    This may seem strange and impractical until you machine them to size in the first shot and then a week later you have a great big pile of scrap parts because of the cold creep. PTFE is strange stuff if you have never machined it before. It is weird even if you have some experience with other...
