I'm trying to produce a thread very close to 5/8-18 by single point threading stainless. I have a 900 piece order, of which 650 pieces ran flawlessly. Now, I've been working all day to get my threads to look proper, but they just keep looking like complete garbage (see picture). Nothing changed in the program. I checked spindle alignment and re-zeroed the tool holders TWICE (no noticeable difference between the two times). I've tried two different style tools (one solid carbide and one with interchangeable inserts) with the same exact result. Great Coolant flow and concentration. It can't be the material since all other operations make the part look like a mirror and I've changed bars and no change. For now, forget about the parameters I'm using since they are the same that ran 650 perfect pieces. Any suggestions on what else may have changed all of a sudden to cause this mess ??? Please Help
