CADICAM Design of Trunnion Mount (Short Communication)

Abstract

The computer-aided design (CAD), computer-aided manufacturing (CAM) of a 3-D trunnion mount located on the intercasing housing of a gas turbine engine is described. The mount carries load and thrust, hence stress-concentrating locations, like sharp edges and comers must be avoided. A program involving CAD, CAM and post-processing CAD surfaces for tool paths has been developed. Preliminary machining of a scrap aluminum piece that verified the program is described. This method is applicable to a wide variety of proprietary packages.
