  • Tool evaluation system and method
    Patent number: 7174796
    Abstract: A tool is evaluated in response to a member of the tool being moved from a first position to a second position. In this evaluation, a first force is applied to the member. The first force is operable to move the member from the first position to the second position. In addition, a second force is sensed. This second force results from a resistance of the tool to the first force. Furthermore, it is determined whether the second force exceeds a predetermined value.
