Abstract: A power skiving method wherein three-dimensional cutter rotations relative to gear workpiece tooth flank surfaces are carried out so as to reposition the cutter relative to a gear workpiece so as to achieve a decrease and/or an increase in the pressure angle of the tooth flank surfaces. The method can be applied independently to left and right flank surfaces of a tooth slot or the rotations may be superimposed on one another to realize pressure angle corrections on both tooth flanks of a tooth slot.

Abstract: Method and Apparatus for fabricating a spacer frame for use in an insulating glass unit. One of a multiple number of possible spacer frame materials is chosen for the spacer frame. An elongated strip of the material is moved to a notching station where notches are formed at corner locations. The character of the notches is adjusted based on the selection of the metal strip material and more particularly to achieve bending of the material in an repeatable, straightforward manner. Better control over the notching process is also achieved by exhaust flow control of a double acting cylinder. A positioning spacer achieve very accurate side to side positioning of a die and anvil to precisely notch and deform the metal strip. Downstream from the notching station the metal strip is bent into a channel shaped elongated frame member having side walls. Further downstream a leading strip of channel shaped material is severed or separated from succeeding material still passing through the notching and bending station.
