PECULIARITIES OF MANUFACTURE OF A ROTOR FOR FLOAT GYROSCOPE IN THE PRODUCTION CONDITIONS

Abstract

The problem of ensuring the performance of high-precision parts of navigation systems, while forming their surfaces by turning, has become extremely urgent today. The use of wide-ranging numerically controlled machine tools for precision spherical surfaces is promising, provided the required shape accuracy and roughness are required. Practical experience with the use of synthetic single-crystal interchangeable diamond plates has shown the need to find technological solutions related to reducing the surface roughness under certain conditions. The article presents the basic data on the technological capabilities of instrument production of manufacturing the parts for mechanical gyros-copes. The algorithm and technological sequence of manufacturing and providing the necessary properties to the surfaces of gyroscope rotor parts made of D16 and B95 aluminum alloys are presented. A description of the manufacturing sequence is given, indicating the tools and equipment used during the operation. A detailed description of geometric parameters of the variable plates with the indica-tion of manufacturers is given. A series of experiments has been conducted to determine the cutting modes by carbide and diamond tools. The influence of flow, speed and depth of cutting have been determined to ensure the minimum roughness of spherical surface of float gyroscope rotor for specific processing conditions. The results of the roughness measurements after polishing the surface obtained with diamond sharpening are presented. The results obtained can be used in the production, in the design of technological processes for the manufacture of parts made of aluminum alloys which have high-precision spherical surfaces. In addition, additional confirmation of the influence of the radius of rounding of the main cutting edge on the roughness of the machined surface has been obtained.
