CONFORMADO

Este método de selección de materiales fue desarrollado por M.F. Ashby en 1992 y radica principalmente en la optimización del proceso de diseño, basándose en la selección más apropiada de materialpara la aplicación establecida.

Manufacturing processes can be classified under the headings shown in
Figure 7.2. Primary processes create shapes. The first row lists seven primaryforming processes: casting, molding, deformation, powder methods, methods
for forming composites, special methods, and rapid prototyping. Secondary
processes modify shapes or properties; here they areshown as ‘‘machining’’,
which adds features to an already shaped body, and ‘‘heat treatment, which
enhances surface or bulk properties. Below these comes joining, and, finally,
finishing.
The meritof Figure 7.2 is as a flow chart: a progression through a manufacturing
route. It should not be treated too literally: the order of the steps can
be varied to suit the needs of the design. The pointit makes is that there are
three broad process families: those of shaping, joining, and finishing. The
attributes of one family differ so greatly from those of another that, in
assembling andstructuring data for them, they must be treated separately.
To structure processes attributes for screening, we need a hierarchical classification
of the processes families themselves, in the spirit ofthat used in
Chapter 5 for materials. This gives each process a place, enabling the development
of a computer-based tool. Figure 7.3 shows part of it. The process
