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...

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.

Sinker EDM????

Swagelok SAT12 is a new austenitic stainless surface hardening process. See the link below http://www.swagelok.com/products/sat12.htm?301Red=Y

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...

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...

On a slight tangent, does anyone had an experience where this certification has helped? i.e. getting a job, higher pay, etc, etc......

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...

[ponder]What is the difference between a motor and an engine???[ponder]

Try HGR Industrial Surplus They may not have your exact model, but you could compare similar models and the going price.

[noevil] mmmmmmmmKay, if you say so... [noevil]

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!!!

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

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...

Here is the link to the Siemens 840D retrofit. I think this may be what you are looking for. They are claiming to be able to run up to 248 axes with this controller.

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...

(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.

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.

You could get a good overview by trying the Modern Machine Shop website. Try here and look under the 'Electrical Discharge Machining Technical Articles' heading: http://www.mmsonline.com/edm/

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...
