摘要： Systems and method relating to machining parts include a CNC system including CNC machining tools, and a computer including a processor and a computer-readable medium, wherein the computer-readable medium encodes instructions of a single NC program that, when run on the processor, causes the computer to control a selected CNC machining tool to perform operations including alternating between (i) moving the selected CNC machining tool along a semi-finishing toolpath segment using a first set of spindle speed and feed rate values to remove a next portion of rough stock material in a next region of a part being manufactured, and (ii) moving the selected CNC machining tool along a finishing toolpath segment to remove a semi-finishing thickness portion of the part in the next region, wherein the first set of spindle speed and feed rate values are different from the second set of spindle speed and feed rate values.

摘要： This disclosure concerns an adaptive repair method, for example for aerofoil blade components. The method generates a digitised model of a physical component and uses data from the digitised model to align a part of the physical component with a nominal CAD model of the component. A combination of the digitised data and data from the nominal CAD model are then used to create an adapted model for repair of the component.

摘要： The present relates to a method for automatically determining a finishing recipe of a manufactured component. A non-finished 3D model, consisting in a 3D representation of the manufactured component at a non-finished stage, is received at a computer. And a finished 3D model, consisting in a 3D representation of the manufactured component at a finished stage, is received. The non-finished 3D model and the finished 3D model are further processed, to calculate a finishing recipe of one or more tool(s), The tool performs a finishing operation according to the finishing recipe on the manufactured component at the non-finished stage, to obtain the manufactured component at the finished stage. The finishing recipe may include a trajectory of the tool(s), an operational parameter(s) of the tool(s). The manufactured component may consist in a blade. The finishing operation may consist in profiling, polishing, tri-blending, weld blending, twist and bow.

摘要： A method for characterising the surface profile of a component comprises the steps of a) dividing the surface into at least two regions; b) for each region, measuring the surface and selecting a number of measured points to define a co-ordinate dataset for the region; c) for each region, applying a curve-fitting algorithm to the dataset for the region to define the surface profile of the region; d) combining the defined surface profiles for the regions to produce a defined surface profile for the aerofoil surface. The characterization may be used in the design, analysis and manufacturing steps of product development, thereby decreasing the total time and work required.

摘要： A visual feedback system and method for airfoil polishing is disclosed. In one aspect there is a system for providing visual feedback during a polishing operation of a workpiece. In this system there is a model having a representation of a desired shape of the workpiece. A scanning system generates a representation of a current shape of the workpiece while in-process during the polishing operation. A comparator compares the current shape of the workpiece to the desired shape of the workpiece. An illumination system highlights the workpiece with visible light during the polishing operation. The highlighting of the workpiece with visible light is a function of the comparison between the current shape and the desired shape. The illumination system highlights a portion of the workpiece that needs additional polishing to conform to the desired shape.
