Fiberreinforced composites have become the preferred material in the fields of aviation and aerospace because of their highstrength performance in unit weight. The composite components are manufactured by near netshape and only require finishing operations to achieve final dimensional and assembly tolerances. Milling and grinding arise as the preferred choices because of their precision ...

Depending on the part, there may be an intermediary stop at a machining center. From the lathe and mill, these parts, now accounted for as workinprocess, go to heat treat for hardening. When they get back, it's off to the grinder for completion.
