Well that is true about the 10. I obviously have a good setting because we have not changed it. I have noticed that when I run a lot of parts one right after the other I must check from time to time as required by our papaerwork QC requirements. I check critical dimensions. It will move some if it cools down so sometimes I guess I do back it off when it is close tolerance. I know when it is good you keep it warm by keeping it running without and downtime between parts. I have stuck to this principle on Mazak and Haas. I have been told these Haas don't need warmup period. I have seen such persons also running warm up programs on occasion. Its funny.
