Problem: Tool shank rubbing on workpiece.

my tool library.csv I TRIED TO UPLOAD THIS, BUT YOUR SUPPORT SOFTWARE WONT LET ME. WHY IS IT SET UP THIS WAY?

test.nc I TRIED TO UPLOAD THIS, BUT YOUR SUPPORT SOFTWARE WONT LET ME. WHY IS IT SET UP THIS WAY?
THEN I RENAMED IT TEST.NC.TXT BUT IT STILL WON'T LET ME UPLOAD IT.
All my own stuff is in mm.
The cutter is a 1/32" = .7938 mm flat end, with length of cut 3/32" = 2.381 mm.
The shank is 1/8" = 3.175 mm.
(The tool actually expands out from the cutting portion to the shank, but I've just described it as having the shank diameter right above the cutting portion.)
Doing some testing, I saw rubbing. The attached files show that the problem is coming out of RhinoCAM.
picture.jpg is a screen shot of the RhinoCAM simulation, showing that when the cutter touches the floor, it is rubbing on the wall.
If we look at the "Toolpath" within RhinoCam, we see that tool touches the floor at
184 GOTO 4.598649,253.400001,31.692927
Since the wall is at 252.4007, this means that the axis of the tool is 1 mm from the wall. But the radius of the tool is 1.5875 mm, so the tool is rubbing on the wall. This agrees with what picture.jpg shows.
The posted file test.nc has
N0108 X4.5998 Z38.7570
N0109 Z39.3148
N0110 X4.5986 Y253.4000 Z39.1382
N0111 Z31.6929
N0112 X-4.6186
showing that when Z hits the floor at N0111, Y is indeed 253.400.
So that's where the rubbing is coming from.
If you look at the toolpath in RhinoCAM, you see a lot of other weird motions.
I look forward to a quick resolution of this problem.
