Custom Tool Geometry issues

[danielm]

Can people please chime in with cutter type and spd/fd combinations for peel mill or z-level milling of 6al-4v that they have found to work well?  I've looked at the dynamic database and there's just not a whole lot there.  

I feel like asking for this kind of info may be dangerously close to asking for a post considering how delicate it is to get Ti to cut just right.  Me personally....I'll put up anything that I've found to work really well.     *I am using one 1.25 insert cutter and solid carbide  .500" (flat) down to .250 ball.

**Is anyone using ceramic for 6al-4v?

Thanks in advance!!

 

 

 

For you guys that are rocking Inconel....this one's mine:

We run a 718 Inconel job faster than I've seen anywhere.

 

Here's the recipe:

1) 1.25dia X 3flt Kennemetal Facemill (.25rad inserts)

2)Kennematal ceramic inserts: KIPR125RP43540

3)4584 RPM and 41.25 IPM.

4).100" axial cut

5)Full dia cut

6)Run dry!

 

Oh yes..

 

7)50 taper horizontal mill.

 

You will see the prettiest color of orange-red chips spewing off the cutter. The work doesn't get hot and you get great cutter life.

Trying to get this custom tool to work.  *chain is good. *no splines. *no duplicate entities. *nothing overlapping. *on top plane. 

I've made many other very similar cutters but this one is not working.

What am i missing?

 

Thanks in advance!

Your Inconel f/s are dead on mine except we are running 2.5in and 4in cutter bodies.  The Green Leaf inserts seem to last longer.

WELL....i deleted the fillets and it worked.  Weird.

could it be the arc center points which are showing where the fillets are?
