Abstract
Abstract A method of testing an assembly which is adapted to move in a predetermined motion through a cycle including the steps of applying a controlled force to the assembly, dividing each cycle of the assembly into a plurality of increments, sensing the force applied to the assembly during each increment, sensing the difference between the highest force and the lowest force sensed during a particular increment, setting a differential force limit for a particular increment and comparing the sensed difference between the highest and lowest force sensed during a particular increment with the set differential force limit and generating a first signal representative of an unacceptable assembly if the sensed differential force is not within the differential force limit.
