Average Width of Fibers
An analysis on the average width of the fibers was performed to check how many were over the desired average width (2.03mm). The width of each fiber was measured at fifteen different points as a part of the cutting process. Histogram A shows the spread of average fiber width; almost all fibers meet the width specification with less than five percent exceeding the threshold width (2.03mm).
In order to gauge how accurately the averages represented the fibers, the standard deviations of the widths were also plotted. On histogram B the distribution of the standard deviation of width of each fiber is shown. Over ninety percent of the fibers' widths deviate by more than .03mm on average. Considering histograms A and B, there are very few fibers that are too large or uneven to use.
