摘要

A method of securing an workpiece (10) for machining the trailing edge (24). The workpiece has a platform (14) from which extends an airfoil (12), the airfoil including a leading edge (22) and a trailing edge (24), and a pressure side (18) and a suction side (20). A fixture (32) with at least one locating datum (58a) that relates to the platform and at least one locating datum (58b, 58c) that relates to the leading edge is provided. The fixture does not contact the trailing edge of the workpiece. The workpiece is positioned so that the platform is against the related locating datum and the leading edge is against the related locating datum. The workpiece is secured within the fixture, and the trailing edge of the workpiece is machined.
