Thank you for the kind words! Usually, anytime you are doing an outside diameter turning path, you would use a G42 ( which means the cutter comp path stays to the right side of the programmed path)and your tool tip direction is usually 3. If you were doing a Inner boring cycle that had multiple dimensions on the inner diameter, that's usually when you would use a G41( which means the cutter stays to the left side of the programmed path)...You would also need to adjust your tool tip direction for this. I personally use G42 all the time on O.D. turing , because I get lazy trying to figure out all the math needed(haha!!)....so I let the machine figure it out.
Hey Tim! Great video, one extra question. How do I determine if I am to use G41 or G42, given tool position 3 (X- Z-)?
