Kind Code:
A1
Abstract:
Provided are an aluminum component and a manufacturing method for the same that are capable of preventing chipping from occurring in spline shapes. The manufacturing method for the aluminum component includes a forming step for obtaining an aluminum cast product having protruding shapes f that extend in the axial direction and are formed continuously over the circumferential direction, and a cutting step in which spline shapes S having prescribed dimensions are obtained by cutting the distal end sides of the protruding shapes f formed in the forming step along a prescribed machining diameter D, wherein the protruding shapes f are configured such that lateral faces fa thereof are sloped in a tapered shape from the proximal end side toward the distal end side, and the lateral faces fa at the distal end side are cut in the cutting step to have slanted faces fb that have a smaller slope angle than the lateral faces at the proximal end side.
