Using Advance VC for a deep inlay

Software
1

Not really an inlay per se, Im sure there’s a simple answer I’m missing.

I just bought CC Pro, its awesome. (Worth it alone for the ramp and rest functions)

In my 1" maple stock, I need a pocket .6" deep (# 3) so I can inset a walnut block which I will then use a bowl bit further inside the block.

Since its got the two sharp corners the advanced V function works perfect at a depth of .12 (#1)

But in Advanced V when I set the depth .6 depth I get that whacky cut.

How can I cut my .6" pocket so the bottom has the nice easy bevel?

I can model it easily , but wanted to see if it can be done w/o.

Thanks in advance

Can you share your file? It’s a lot easier to experiment with a known baseline.

Have you exceeded the cutting diameter of your vbit? You don’t mention the vbit angle, but I can imagine something like that if you are deeper than the depth of cut on the bit

Thanks guys

Sorry I wasn’t clear. Yes it’s a 90 degree bit but I think that’s it, I exceeded the diameter.

I whipped this up in 3d max real quick to better illustrate.

Its an inlay block, (ill level off) and use bowl and tray bit.

But since I have rounded and sharp corners in the inlay block I thought that was a job for the advanced v carve?

I have a 90, 60, 45 and 30.

When using Advanced V carve it is necessary to keep the cut w/in the limits of what the V tool can cut at the end of multiple passes w/o running out of flute length.

So this would be a job for 3D tool paths?

Or you create some extra paths to remove the remaining material.
Offsetting the vector & following it with the V tool at appropriate depths.
If it’s a 1/2" dia 90° Vee, the flute length is 0.25", so if you offset the edge 0.2" & cut a depth of 0.2", then offset 0.4" and cut 0.4" deep, it will clean up those edges.
