DESIGN AND IMPLEMENTATION OF THE SYSTEM OR THE AUTOMATED DESIGN OF STAMPING OF COMPRESSOR BLADES MADE OF TITANIUM ALLOYS

Abstract

Algorithms of calculation of the design of a billet and stamping equipment for production of compressor blades of aircraft engines made of titanium alloys are developed. The proposed system of design makes it possible to automatically form the charts of cut and crimp dies, which considerably shortens the time of the manufacturing preparation of production. A detail analysis of the features of constructive elements of the blade is presented. The accepted limitations and manufacturing solutions allowed us to form the generalized algorithms for the formation of the surface of splitting the stamps over the loop contour for various configurations of stamped forgings. Algorithms and programs of calculation of three-dimensional coordinates of the points describing the configuration of the stamp cavity, base surfaces for establishment of control templates as well as the shape and scale sizes of the upper and lower stamp inserts. This was resulted in a generalized mathematical model of a final stamp in a form of a three-dimensional array of side points connected by edges in a form of straight lines or splines. It can serve for the formation of the design documentation of the production equipment and its control means.
