Abstract

For creating of modern engines and ensuring their serial production becomes a matter of priority to develop a model of formation of a strategy to improve the efficiency of production on the basis of new technical solutions and improved processes to create products.

Particular attention should be paid to high-volume engine components. The most common items are the gas turbine engine compressor blades. The currently existing in RF technology of production of compressor blades is not unequivocal, the principles of its construction is not structured.

The purpose of this work is to increase the efficiency of technological process of manufacture of compressor blades of turbojets. The authors analyzed the technical process using the tools of quality management, built-up the flowchart of process and identified one bloc that needed to be modified.

Workpiece production is the most resource-intensive stage in the process. It is performed by hot extrusion and hot stamping. The matrix for stamping is a very expensive and responsible element of technical process. Operations on its production are very labor-consuming and include locksmithing work by a worker. To avoid this non automated operation, we take a stamp after locksmithing changes and after receiving on her correct workpieces of blade, and scan it. Stamp for producing blade workpieces was scanned by CMM machine. Based on it the 3D model of stamp has been designed. From 3D model we can create new drawings for production.

The proposed process can be used for improving the technology of producing blades that are already applied in aviation industry, and to ensure the high effectiveness of new blade standard size production.
