  • Flexible fixture system for machining operations
    Patent number: 8424858
    Abstract: A flexible fixture system for a CNC machine is coupled to a base fixture. The flexible fixture includes quick connects that connect with the base fixture in order to allow hydraulic fluid, air, and water to be communicated from the base fixture to the flexible fixture system. The flexible fixture system includes features operable to hold a workpiece within the CNC machine. The flexible fixture system is modular and may be swapped out for a different flexible fixture in order to allow other operations to be performed on the workpiece.
    Type: Grant

  • Method for checking cam lobe angles
    Patent number: 6449044
    Abstract: An apparatus and method for verifying the lobe angle of cams on a camshaft. Laser beams directed on cam lobe surfaces and a timing indicator during camshaft rotation are reflected to receiving elements that provide distance data to a computer also fed with encoded information on the angular positions of the camshaft lobes. The computer calculates the relative angles of the cam lobes which are compared to a standard stored in the computer to qualify the camshaft and verify the operation of the assembly process.
