19.19.2 Applying diameter correction
After the workpiece been ground on the machine and inspected you may find that the results of the
measured diameter from your inspection department differ to the required size as per the workpiece
engineering drawing.
Therefore, the same workpiece could to be re-ground on the machine in order to achieve the correct
size OR the next workpiece to be ground will be applied with the diameter correction.
diameter error = measured diameter – active machine diameter
if the diameter error is -ve then enter a negative value into the diameter error input field
if the diameter error is +ve then enter a positive value into the diameter error input field
For example,
active machine diameter = 50mm
measured diameter after grinding = 50.02mm
Therefore, the diameter error is 50 - 50.02 = -0.02 = - 20 microns
