    Default X axis not precise

    Cutting 2 different diameter with the same tool, first a 3 inch than a 5 inch . If I set the 3 inch diameter right on than the 5 inch diameter is .003 bigger. If I set the 5 inch diameter to be good then the 3 inch diameter is smaller. 003. What parameter do I need to adjust to compensate for that. This is a Samsung fanuc oi-td 3 axis machine 2014. I have the parameter manual but I have no clue which parameter to look for. Otto

    Default Re: X axis not precise

    I would start with the feed rate. The feed can mess with the size and shape. Or use cutter comp and add a different D for each hole diameter.
