Please let me understand the following:

In McX5, Contour Toolpath / Cut Parameters we have under compensation type several choices but I always choose “Computer”

Then we have Compensation Direction and the options are Right or Left

My understanding is in the "Left" the endmill will cut on the outside of a line and the "Right" will cut on the inside of a line.

So if I want to cut a square 4"x4" if I use the left I will get a 4x4 square and if I use the "right" I will get a smaller square (endmill diameter x 2).

Is this correct?

Thank you
