Fabricated vehicle wheel and method for producing same

A method for producing a fabricated wheel disc comprising the steps of:

• (a) providing a wheel disc defining an axis and having a wheel mounting surface, a plurality of outwardly extending spokes and an outer rim connecting flange defining a side edge surface;
• (b) subjecting the wheel disc to at least a first window piercing operation to produce a first window portion in the wheel disc between a pair of adjacent spokes;
• and
• (c) subjecting the wheel disc to at least a second window piercing operation to produce a second window portion in the wheel disc, the first window portion and the second window portion cooperating to define a single pierced window in the wheel disc having a predetermined shape defined by the adjacent pairs of spokes and the side edge surface of the rim connecting flange such that each of the pierced window extends to an outermost periphery of the wheel disc.

A method comprising the steps of:

• (a) forming a first window portion in a wheel disc between a pair of adjacent spokes of the wheel disc and a side edge surface of a rim connecting flange of the wheel disc;
• and
• (b) forming a second window portion in the wheel disc which cooperates with the first window portion to define a single pierced window in the wheel disc having a predetermined shape defined by the adjacent pairs of the spokes and the side edge surface of the rim connecting flange of the wheel disc such that the pierced window extends to an outermost periphery of the wheel disc;
• wherein the first window portion is formed by piercing through a first plane of the wheel disc and the second window portion is formed by piercing through a second plane of the wheel disc.
