I am studying Cnc programming and I got stuck on the difference between G41 and G42. The lecturer didnt explain it clearly so Im looking for somebody who can give me a clearer explaination of the difference. I know they are both cutter compensation, but how do I know when to use G41 and when to use G42?

Its actually quite simple to determine the difference between G41 and G42. But if you get it wrong, It could be a really costly mistake. G41 compensates your cutter to the left, and G42 compensates your cutter to the right.

You can read more about it here: Cutter compensation G40 G41 G42
