In a third step, the partially machined blank may be held by at least one clamping adapter in the first, finally machined region and the remaining region may be brought into its final, ready to use overall form by the same machine tool or milling machine. | ||||||

| 57 | Method for shaping an airfoil | US755172 | 1976-12-29 | US4149449A | 1979-04-17 | Eugene J. Malinowski; Raymond J. Zyck |
| An improved method and apparatus are utilized to shape the leading and trailing edges of a tapered airfoil having twisted ad bowed major side surfaces. To compensate for taper, a rotatable forming tool is moved inwardly toward the longitudinal axis of the airfoil as the tool is moved through a working stroke along an edge of the airfoil. To compensate for the bowed side surfaces, the forming tool is pivoted in such a manner as to maintain its axis of rotation perpendicular to an arcuately curved edge being shaped by the tool. To compensate for twist, the airfoil is rotated about its central axis to maintain a major side surface of the airfoil in abutting engagement with a positioning or locating roller disposed adjacent to the edge forming tool. The locating roller rolls along a major side surface of the airfoil to position the edge portion of the airfoil and the forming tool relative to each other as the forming tool moves along the twisted edge. | ||||||
