Abstract: The present invention provides a method of forming a leading edge for an aerofoil component e.g. an aerofoil blade. The method comprises forming a pre-form having a precursor edge and processing said precursor edge to form the leading edge. The pre-form is formed using metal injection molding. The leading edge may have an elliptical profile.

Abstract: A method for controlling the machining of a component includes the steps of: (i) measuring predetermined dimensions of a component; (ii) comparing the measured dimensions against design data defining a required shape for the component; (iii) using the results of the comparison to define material removal that is needed to bring the component to the required shape; (iv) delivering the component to a site at or adjacent to a machining station having a material removal tool, the component being gripped by a robotic manipulator at said site; (v) using the defined material removal and the known position of the robotic manipulator at the machining station to determine movements of the material removal tool that will produce the required shape for the component; and (vi) performing a machining operation on the component at the machining station using the determined movements while maintaining the grip on the component by the robotic manipulator.

Abstract: A method for measuring the profile of a component in the region of an edge of the component comprises the following steps: determining the position of an edge point of the component; defining a center line for the component in the region of the edge; and measuring at least one dimension of the component with reference to the center line.

Abstract: A method for performing a machining operation on a part uses closed-loop control, based on feedback of information measured from the part, from the tools and machines, and from the environment, to modify the controlling parameters for the machining operation. By recording the information for all machining operations, statistical data can be generated, and the process control can be further improved by applying this statistical knowledge. Information relevant to each part can be stored, so that it can be passed on to subsequent operations in the manufacturing route.

Abstract: A method for measuring the profile of a component in the region of an edge of the component comprises the following steps: determining the position of an edge point of the component; defining a centre line for the component in the region of the edge; and measuring at least one dimension of the component with reference to the centre line.

Abstract: A stackable container lid for a bucket containing hot foods and the like comprising a generally circular lid having center portion surrounded by a series of polyhedrons, one plane of which extends upwardly at right angles from the lid surface thereby forming a perimeter into which the bottom of the bucket can be inserted. The lid may also contain vent holes in a rim on the outer perimeter of the container lid. The rim terminates in a downwardly extending lip adapted to snap over the top of the bucket in a sealing relationship.
