I'm new to swiss turning and I need some help. Trying to single point thread a 1/4-20 thread 3.00" long. I was trying to turn a .500" and thread a .500" and do it again and again till I get 3.00" but when I try to pick up the threads there is a mismatch every time I try to continue the next cycle of threads. Please Help. Using hanwha with fanuc controls. Thanks.
