The cam was converted from a machined solid billet. The investment casting, weighing 1 lb., eliminated machining of the component. The casting supplier was able to produce the cam tracks and spline in near-net-shape. Signicast also provided the star shape on the end of the casting that was previously a secondary component pressed onto the original machined part. Overall part performance was improved due to a reduction in weight, which resulted in less rotational inertia.
