Dave,
Before I got Bobcad, I used to draw all my parts in autocad and draw the
offset "toolpath". If you place the center line of the part on the horizontal
y origin line and offset it correctly left to right for the correct "z"
numbers, the locations of the tool point will show up directly in the cursor
location "dro". I've often drawn the tool along with the insert and moved it
around the profile in question to be sure I had no gouging etc. Manual CAM if
you will. Works well as there is no need for cutter comp codes etc.
If you insist on the mathmatical procedure, I'm not the right guy for you:)
