Cutting a Face Cam, Using the Cam Cutting Attachment
In this operation the head of the attachment is bolted to the bed at right angles to the table and the cam blank is fastened to the attachment spindle by means of a bolt. A peripheral cam would be milled in the same manner. The necessary rotative movement is obtained by hand feed, and the longitudinal movement to give the proper lead and shape to the cam is produced by the cam former and the mechanism of the attachment, as described in Chapter V.
A spiral end mill is used. The machine table remains clamped in one position.
