Abstract

A method of manufacturing a feature in a part with a cutting tool, includes machining a semi-finished shape of the feature, determining an actual position of at least one target point on a surface of the semi-finished shape, and computing a difference between the determined position of the at least one target point and a nominal position of the at least one target point on a digitized model of the part having the semi-finished shape of the feature. As a function of the difference, a correction to a position of the cutting tool on a nominal tool path to achieve the final shape of the feature from the semi-finished shape is determined, and the correction is used to define a corrected tool path. The finished shape of the feature is then machined with the cutting tool by moving the cutting tool along the corrected tool path.
