    摘要： A bore finishing tool has an arbor with a tapered outer circumferential surface and a sleeve over the arbor having a tapered inner circumferential surface cooperatively disposed in surface to surface overlaying relation to at least a substantial portion of the tapered outer circumferential surface of the arbor. The sleeve is adjustably movable relative to the arbor for expanding a diametrical extent of the sleeve and has a plurality of internal material relief features at circumferentially spaced locations in the tapered inner circumferential surface extending partially through the sleeve so as to reduce a level of force required for expanding the diametrical extent of the sleeve. Exemplary material relief features include flutes and fractures. The sleeve can also include an external retraction feature enabling application of a retraction force by an external device for reducing the diametrical extent.

    摘要： An automated bore finishing process particularly adapted for lapping automatically corrects one or more bore parameters, such as diameter, geometry, surface finish, in an iterative manner to reach a final value, controlled by algorithms that process feedback from a measurement process. The process determines bore parameter information and determines an optimum set of values for the process parameters, such as stroke position, stroke length and duration of the next lapping iteration. This optimization is targeted to achieve the desired final bore parameter or parameters within the specified bore size limits, and may be used to alter the stroke profile either for the entire next iteration or in a continuously changing manner, to minimize or eliminate bore defects over one or a succession of iterations.
