Hi All,
I have inherited a design of camshaft that has induction hardened cam surfaces with a case depth of ~2mm. The shaft diameter lies ~3mm below the base circles of the cams with a generous fillet radius transitions between the shaft and cams that run out just below the base circles. This means that the case layers run out (transition back to parent metal) part way through the fillets. Is this an acceptable condition or could this give rise to a risk of failure? Is there anything that can be done in manufacturing to mitigate any risk?
Many thanks,
Dave
