Abstract:In order to improve the design and manufacturing efficiency of the personalized customized car steering wheel, a method to design the steering wheel model rapidly with the equation function of 3D CAD software was given, and a method for the rapid manufacturing of the steering wheel model was also presented based on the semifinished steering wheels that were prefabricated beforehand, which were machined using front and back milling process combined the layered manufacturing and CNC machining. At the same time, the modeling of 3D process model and the generating method of CNC milling were presented, and the steering wheel model was completed in the threeaxis CNC milling machine.
