  • Method and apparatus for machining crankshafts or camshafts
    Patent number: 7588397
    Abstract: An apparatus and method are provided for performing multiple machining operations on a workpiece such as a crankshaft. Oil holes may be drilled in a crankshaft by a tool shifted along a curved path between successive, acute angle tool plunging locations. The tool's carrier is shifted parallel to the crankshaft axis and the tool carrier is rotated to the desired acute angle about a point on the crankshaft axis for each of successive oil hole drilling locations thereby reducing programming needed to drill the oil holes at the specified angles. Offset tolerance errors are reduced by a large factor as the tool is plunged from an outer initial position toward the crankshaft axis.
