The 1:32 scale F1 wheel project was used to train new undergraduate intern students on the fundamental of freeform shape machining. High speed machining centers were used in conjunction with Esprit in order to develop simple Z-level roughing toolpaths and then more complex spiral finishing toolpaths to achieve good surface quality.
