The cam is mfd. with a shaped circumferential contour (2/1) by size and/or form deviation. The circumferential contour is formed without any finishing treatment by process heating and deformation conditional on the final working contour (2). With a sintered or forged cam, the external contour of the annular section (6) is mfd. as an oval (8) having constant transitions, or as an ellipse, each with a principal axis (9) at right angles to the cam section (4).
