Abstract
The present invention is a method of determining the crimp height of an electrical terminal being crimped to a wire during the production crimping cycle. The method includes collecting a plurality of force and position data element pairs which are measured and sampled during the actual crimping operation. These data element pairs, representing the work curve of the operation and are analyzed to find the position of the ram when the crimping die set just disengages the terminal being crimped. The position of the ram at this point is then translated into the crimp height of the crimped connection. The analysis of the data element pairs includes a filter to remove inconsistent or extraneous data element pairs which could adversely affect the result by indicating an erroneous crimp height.
