Example 9 Histogram Showing Thickness Distribution of 90 Cadmium Plated Components

The small cylindrical part shown in Fig. 10 was plated in a horizontal barrel. The load contained about 5000 pieces. Thickness of plate was measured with a magnetic gage on 90 parts from each load. Plating thickness ranged from 5 to 14 ^m (200 to 560 ^in.).
