  • Edge sharpness measurement
    Patent number: 9651466
    Abstract: An edge sharpness measurement apparatus includes a clamp for securing a test medium against a frictional member, and an engagement mechanism for a normal force, such that the normal force directs the test medium against the frictional member with a force based on operational conditions of the test medium. A further engagement mechanism is for a tangential force, in which the engagement mechanism is adapted to increase the tangential force to identify a tangential force sufficient to dispose the frictional member across the test medium. A pivot defines an angle of application of the tangential force relative to the normal force, such that disposing the frictional member across the test medium defines a point of overcoming frictional forces between the test medium and the frictional member. A measurement device, such as a gauge or range on a spring, measures the tangential force sufficient to dispose the frictional member.
