What are "normal" limits...??? Point Check on Romer Infinite Arm

kejay74
Below is summary data returned for a 66 point check result. As I am in process of "remembering" how to do a lot of this I am not comfortable with WinRDS (CimCore) utilities...but...have been called on to resolve some (perhaps) anomalies that have recently occurred. To my "intuition" a fit error of .085 (and I assume millimeters) is rather large. Anyone have any comments?

Thanks,

KJay

Serial No: 5124sc-227

X Y Z
Minimum: X = 131.666 Y = -690.005 Z = 88.543
Maximum: X = 131.772 Y = -689.893 Z = 88.681
Average: X = 131.715 Y = -689.944 Z = 88.616
Range/2: X = 0.053 Y = 0.056 Z = 0.069
Std. Dev.: X = 0.023 Y = 0.022 Z = 0.037

Max. Fit Error: 0.085

  • full instructions for both the Point Checkout and Length Checkouts are contained in the Arm Utilities User Guide. You can access it via the Start Menu under "cimcore".

    We perform the Point Checkout to test the arm+probe+setup's repeatability.
    We perform the Length Checkout to test the arm+probe+setup's volumetric accuracy.
    Both are critical to getting good numbers when we inspect with PCDMIS.

    Note that for Point Checkout, we only care about the Range/2 in X and Y and Z. None of the other numbers matter. for a 5124, you should be < 0.028mm

    For the Length Checkout, we care about the max and min length of the bar (your max length should be less than the Bar Length + 0.040, min should be Bar Length - 0.040), and about the Range/2 (should be less than 0.040).

    again, please read the Arm Utilites userguide for detail on how to perform/interpret these checkouts.
