After single point external threading some 6061 M10x1.5 pieces I was taking one pass with a OD tool to clean up the OD and then wanting to take one more pass with the threading tool to clean up the remaining burrs from the threaded area.

Added another threading process with the start and finish X .001” above the root diameter and set thread height to .0005”. The least amount of passes it would take was 5 regardless of any combination of start height or thread height.

On another control it has a feature to run one pass at the finish depth after the OD clean up. Is there a simple way in Mazatrol to set up one pass at the finish depth or if I use a manual program using IPR will it pick up the thread start point?

Check parameter U55. That is the # of finish passes. If I set it to 0 or 1, it will thake one finish pass. I can set my # of (regular) passes to a minimum of 3. Any less and it alarms out. It makes 3 passes with those settings. I too would be interested in bringing it down to 1.

U55 is set to 0, I did get it down to 3 but that's the best it will do.
