Using and Measuring Precision Balls
To account for production variation between units, manufacturers typically measure balls in lots of ten. Calculations of lot mean diameter (DmL) and lot diameter variation (VDL) are based on the mean diameters of the largest and smallest balls in the lot, as follows: DmL = (Dm max + Dm min)/2. VDL = Dm max - Dm min See Figure 2 for the ...
