Need help understanding CC outside/right, inside/left, etc toolpath settings

Been using CC and really enjoying it for 2.5d stuff, but was hoping for some help understanding the toolpath “Offset Direction” settings. Can someone please explain the differences between Outside/Right, Inside/Left, & No Offset?

Are these just different terms for Climb and Conventional milling? Or what?

Thanks for any help!

Every cutting bit has a diameter. Say for instance .25 inches. If you have a 1 inch square that you want to cut out, and choose Outside Right, then the software automatically accounts for the 1/2 the width of the tool and you will end up with a true 1 inch square in the center. If you choose inside, then the outside portion of the cut will be exactly 1 inch, the inside will be .25 less on all sides so it is almost like a .5" inside square. If you choose no offset then you will end up with a 1 inch - 1/2(.25) on the inside and 1 + 1/2(.25) on the outside of the cut.

This assumes you accurately put in the correct diameter bit in the software so it can calculate the tool path properly.

Hope that helps?

It does @rogwabbit , thanks very much!

As a follow up, I think I see the use of cutting it on the Outside Right, ie if you wanted to make an object or a boss that is 1" square, and Inside Left makes sense if you are trying to cut a 1" square hole in a larger part, but what would be the use of No Offset? Is it just for slotting?

Thanks again for the help!

No offset is good for Slotting as well as engraving pictures and text and etching, also used with drag knifes typically.
