Hello fellow machinist, Im not new to the manual lathe metalworking but completely new to cnc and the proramming that goes with it. I had one day of training and a lot of reading and self taught days, but I want to learn more than just basic turning and drilling codes. Curious to see if anyone can recomment a book or two that go into details on the codes (i.e G,M,I, U..etc) better than the manuals provided with the machine and more user friendly. Between the books for fanuc controls and the book provided by the manufactur of the machine, I get different discriptions. Thanks people!!!
