New computer simulation software has revolutionized the designing of induction coils and can easily predict the expected case depths, hardness and the heating time based on a specific frequency selection of simple work-piece shapes. However, when shapes become more complex like a flanged axle with various dimensions and radius the simulation software has trouble with both designing the coil and the required heat time, much less the expected case depth. The presentation will show several case studies of complex workpiece shapes with video and photos showing how case depths can be predicted by tried and true old school techniques. The various coil designs suggested by simulation software for specific work-pieces will be shown and what the final production coil design and the final case depth resulted with these proven techniques.
