INVESTIGATING THE VARIETIES OF AIRCRAFT MACHINE PARTS MADE FROM DIFFICULT-TO-PROCESS LOW STRENGTH METAL ALLOYS

Abstract

Machine parts made of alloys of low rigidity are mainly used in special equipment or aircraft due to their lightness and strength properties.

For aircraft manufacturers, it is important to use efficient modern technologies in production, which would allow to use alloys with the set properties.

Tool manufacturing companies are actively studying the cutting processes in difficult-to-process materials to ensure the desired quality, reduce the cost of manufactured parts, as well as to develop solutions to achieve the highest possible productivity. First of all, this concerns the formation of tools of special geometry

The subject of cutting difficult-to-process materials is revealed by the type of processing (turning, milling, drilling) and the characteristics of various difficult-to-process materials, such as low rigidity.

Still in 1974, V.N. Poduraev mentioned in his manual on cutting hard materials: “In the process of cutting, a large number of closely related phenomena occur that make up a complex physical and chemical processing mechanism․ Therefore, it is important to consider the specifics of machining of typical materials by cutting.”

Based on what is mentioned above it is necessary, first of all, to study those areas and those parts of machines where difficult-to- process materials and metals are used.

This article presents a variety of parts made of difficult-to-process metals and analyzes the grades of materials used. The materials were classified according to the cutting processes used, the degree of machinability, flow and plasticity characteristics.
