Anybody else use thread mill tool path to mill holes

[ostie01]

I do it very often (not in a blind hole)

This way, I can use the end mill in its full length.

Less vibration too when entering the material because the end mill is moving up at the same time.

Like Dynamic Milling, but using the Threadmill toolpath to create motion.

That seems like an odd choice.

->area mill with profile ramp is good

->dynamic mill is good

->pocket could be good as well

~>helix bore is a good on too, altho It can

cause trouble

Oh i see, I don't know that toolpath, I never worked in a shop that had the tool for it.

Is there am advantage to that?

That's what circlemill is for

Circle mill is good for t-slot undercuts on holes as well..

Sometimes it makes a round toolpath wheel thing though.

My coworker did it in front of me it looked really cool. Dangerous though.

Sorry if I did not express myself better than that.

In the past,  I saw so many $150.00 end mill in the trash can at work because the bottom 1/4in was dull with 3/4 of the flutes being brand new.

So now that I'm the one paying, I try to use that $150.00 end mill to its full capacity

Sometime for through holes, I use the thread mill toolpath, set the depth to approximately 90% of flute length and adjust the thread pitch for the better use of the end mill and sometime reduce vibration by varying the pitch. I'm sure there are a lot of way to do the same thing but, for me, this is the way I find to be the easiest.

If the flutes are 1in in length, I start at 0.900in deep.

I'm not sure but, this seem to work better on a haas mill when using wear comp in small holes.

Contour can be set to oscillate up and down at what ever pitch you want too
