The above sounds implausible for many people involved in Earing measurement, but Huxley Bertram’s Earing measurement expertise and equipment are making this a reality.
For those uninitiated in Earing Measurement, what is it? Earing is a pattern of waves around the open end of a drawn cup. Which are caused by the grain structure of the metal making the metal more willing to plastically deform in certain orientations than others. Measuring this profile of waves and finding the peaks and valleys is the basis of Earing measurement. Typically, there are 4 or 6 peaks (ears) around the rim of the drawn cup and measuring the difference between the average peak and the average trough as a percentage of the height of the cup, called “Mean Earing”, is the primary metric in earing measurement...
