Abstract
There is described a method of producing a cam for a jointed camshaft by sintering a compact made from a sintering powder, which is calibrated after sintering and then subjected to quenching and tempering. To avoid extensive rework, it is suggested that the compact be pressed, sintered and calibrated corresponding to a desired contour (4), which differs from the desired contour (1) of the cam contrary to the distortion (3) produced during quenching and tempering, and that the calibrated compact is then given the desired contour (1) of the cam due to the distortion (3) produced during quenching and tempering.
