Shoulder Turning Operation.
(a) The first important step in machining a circle is to locate theshoulder correctly. Usually, the position is marked by bluing the workpieceafter it has been rough turned to the large diameter, accurately indicatingthe shoulder location with the hermaphrodite calipers (figure 27 on page63).
(b) The small diameter portion of the workpiece is then turned down by aseries of roughing cuts taken toward the shoulder. Take care to stop thetraverse of the cutter bit about 1/32 inch before it reaches the scribedline; this 1/32 inch is important because it leaves sufficient metal on theshoulder to provide for facing operation after the smaller diameter portionhas been turned to size.
(c) An alternate method of shoulder turning is to cut in at the shouldermark with a parting tool. If this is done, be sure that the bit does notcut deeper than the required small diameter for square finished shoulders,or deeper than the small diameter less the radius of the intended fillet ifa fillet is required. However, if the shoulder is to carry a bearing, itmay be desirable that and
FYI.
