There should be a parameter that you can set to the radius error you can live with, on the Fanuc's I have used it was 3410 but that may depend on which Fanuc control. On some controls I have changed this radius tolerance to 0.5 inches or more because they will then cut a smoothly changing radius from start to end, other controls are less useful and just cut the arc at the starting radius and then add a straight line move at the end to get to the programmed finish position. __________ Andre' B.
