5axis swarf going below floor surface on sharp edges

[LucasGC]

Hello,

First post here. I've been figuring this program out as I go, but I've hit a snag I just can't figure out.

I'm using the 5 axis swarf milling tool path to cut out a simple chamfer on the inside of a flat 8mm plate. So I'm chamfering the inside of the square, not the outside. 

When it gets to the corners and has to make the sharp edge where the chamfers merge, the tool extends past the floor surface, which I have checked in the cut pattern box and have a clearance of 0.1mm.

This is a problem because I'm cutting a soft material and if I get into the MDF spoil board I'm afraid it will dull the bit. 

If I have to avoid those corners and cut them after the swarf tool path that is fine, but I don't want to get rid of the whole tool path.

Or I suppose if I were cutting enough of these parts I could go in before hand and cut grooves in the fixture with a different tool.

But surely there is a way to get this floor surface command to work.

Ah, shoot. I done figured it out. I had been selecting the part surface as the floor but what I was chamfering already had the floor cut out. Just had to add a flat boundary surface and select that, sorry y'all.

Thxbye
