Abstract
Cam lobe packs and methods of producing the same. The method uses a tool made up of an insert disposed within a sleeve such that both are responsive to a dynamic magnetic compaction (DMC) pressure source. The insert defines a substantially axisymmetric exterior surface and a cam lobe-shaped interior surface that can receive a compactable material such that upon DMC, the material is formed into the shape of the cam lobe. The sleeve is disposed about the insert and defines a substantially axisymmetric exterior surface such that an axisymmetric compaction imparted to the sleeve by the DMC pressure source forms the desired shaped cam lobe. The tool is configured such that individual tool members corresponding to one or more of the cam lobes can be axially aligned so that an aggregate interior surface is formed that defines an exterior surface profile of a camshaft being formed.
