Excelent video, thank you very much. I have some questions: 41:53 you say: "that it's very important to note that the tool diameter must be the same, whatever you plan to use for your finishing, you must use the same diameter for your rest machining, so that you leave the same radius and you leave the same amount of material even on the corners", but if I apply a Rest Machining before the Finishing operation, of the same tool diameter, I must keep the same offset, lets say 0.2mm, right ? so the Finishing operation removes the remaining material on the corners. Can you tell me if that is what you mean?.
