Abstract
A machine (10) for forming grooves and splines in workpiece (32) including a mounting assembly (26,28,34,36) defining a support axis for rotatably supporting the workpiece (32) for rotary movement about the axis, and dies (38,40;90,92) including opposed spline forming toothed work surfaces (46) spaced on opposite sides of the support axis for forming splines therein when the work surfaces (46) are moved relative to one another. Each of the dies (38,40;90,92) include a body portion (68) having an elongated straight slot formed therein transverse to the toothed work surfaces (46). A groove forming element (48) removably mounted in the slot simultaneously deforms the workpiece to form a groove as the toothed work surfaces (46) form spline in the workpieces. The groove forming element (48) has a constant width when viewed in transverse cross section and has a portion secured in the slot and a groove forming edge extending from the slot. The edge has leading portion and a trailing portion. The element progressively increases in height above the work surface from the leading portion (58) to the trailing portion (60). The edge becomes progressively squared in transverse cross section from the leading portion (58) to the trailing portion (60).
