Computer-Aided Design of Die Tooling for Large Parts of Airfoil Profiles

The article describes the developed computer-aided design (CAD) systems of die tooling for large parts of airfoil profiles made of aluminum alloys characterized by a high degree of unification and integration which makes it possible to reduce the design time for die tooling tenfold. The paper gives a special focus on the analysis of the design object and the structure of information support of CAD systems of die tooling of airfoil profile parts. All in all, it is possible to develop the means of providing a complex system that performs the design and documentation of blank structures, the necessary technological tooling and the formation of programs for milling the dies on machines with NPC due to the computer-aided design for the blank production objects in large-sized airfoil profile parts. The use of the proposed methods and developed means of computer-aided design of objects of technological preparation of blank production makes it possible to reduce the time of preparation of production by 15–20 times while improving the quality and accuracy of design solutions. Thus, created on the basis of the introduction of computer technologies, advanced domestic and foreign experience, CAD DT of large-sized details of the airfoil profile contribute to the solution of the urgent problems of production modernization.
