  • Cylinder block and method of machining same
    Patent number: 8863722
    Abstract: A machined shape of a bore is based on the deformation amount of a data-acquisition bore after fastening of cylinder head. A cross section of an approximate shape is set to be an approximately-true circle shape, and a diameter of the approximately-true circle shape is changed along a central axial direction in accordance with the deformation amount of the data-acquisition bore, to determine the approximate shape. The approximate shape has a cross section having the approximately-true circle shape and has a simple shape which is symmetrical about the central axis. Since the machined shape of the bore is the shape obtained by reversing a phase of a recess and a projection of the approximate shape about a predetermined cylindrical shape, the machined shape has a cross section having the approximately-true circle shape and has a simple shape which is symmetrical about the central axis.

  • HOLE-FORMING MACHINE
    Publication number: 20100219166
    Abstract: A hole-forming machine for forming a through-hole (75) in a workpiece (66) by directing laser light (70) from the exterior of the workpiece into a hollow part (67). The machine includes a vibrating mechanism (56) for causing vibration in a filler (65) which fills the hollow part of the workpiece (66) and which is not melted by the laser light, the vibrating mechanism being disposed so as to be in contact with the filler.
