Abstract

Abstract A cam generating apparatus includes two slides movable in mutually perpendicular directions on a base. One of the slides, called the X-direction slide, carries a master cam. The other slide, called the Y-direction slide, carries a cam follower which engages and follows the contour of the master cam. A pair of adjustable proportioning arms connect one with each of the slides to provide X-and Y-direction outputs which are proportional to the movements of the slides. These outputs drive a cam blank relative to a cutter to generate a cam contour having an amplitude and a length which are proportional to the configuration of the master cam. Cams of several types including rotating and non-rotating cams can be generated from the same master cam, depending on how the outputs are connected to move the cam blank.
