Abstract:
Method for machining a surface of a bore having a central axis which is also an axis of rotation for a honing tool, the method comprising:machining the bore with a honing tool through a first forward stroke and a first return stroke of the first tool, at a relatively lower axial speed and a relatively higher rotational speed such that machining tracks resulting from the machining are within five degrees of perpendicular to a central axis of the bore; and machining the bore with the honing tool through a second forward stroke and a second return stroke in which the axial speed is increased and the rotational speed is decreased, such that crosscut tracks are produced at a greater angle from perpendicular than the machining tracks from the first forward stroke and first return stroke; and wherein said crosscut tracks are made to a substantially same depth during the second forward stroke and the second return stroke.
