Abstract
The semifinished casting for an alloy road wheel undergoes three successive machining operations in which material is removed by stages to produce an inner circumferential seating, destined ultimately to accommodate one bead of a tire, a center hole coaxial both with the inner seating and with the axis of rotation of the wheel, also a set of fixing holes of which the axes describe a circle centered on the axis of rotation, and finally, an outer circumferential seating destined to accommodate the remaining bead of the tire, which is offset from the axis of rotation in such a way as to achieve a non-uniform distribution of mass, limited to the part of wheel affording the outer circumferential seating, that varies progressively with the change in angular position around the axis of rotation between a maximum and a minimum value.
