Abstract
A composite structure includes a base and an auxiliary portion of dissimilar materials. The auxiliary portion is shaped by stamping. As the auxiliary portion is stamped, it interlocks with the base, and at the same time forming a desired structured feature on the auxiliary portion, such as a structured reflective surface, an alignment feature, etc. With this approach, relatively less critical structured features can be shaped on the bulk of the base with less effort to maintain a relatively larger tolerance, while the relatively more critical structured features on the auxiliary portion are more precisely shaped with further considerations to define dimensions, geometries and/or finishes at relatively smaller tolerances. The auxiliary portion may include a composite structure of two dissimilar materials associated with different properties for stamping different structured features.
