Design of mold for helicopter composite rotor blade

Abstract

This paper shows CAD/CAM programming technique of mold recess for helicopter main rotor blade. It is necessary to achieve high precision in this process. Due to the dimensions along one of the blade axis, the segmented mold is found necessary. In this paper the programming procedure is shown for one of these mold segments. The tool path simulation is shown as well as producing of APT and NC code with the verification of material removal. For realization of these processes CATIA’s and Pro/Emgineer’s tools were used. For chosen mold segment, machining has been done on machining center.
