Introduction

The creation of a material and technical base and the need for a continuous increase in labor productivity poses very important tasks for machine builders.

The main requirement for modern production - to give as many products as possible of the best quality and with the lowest cost - refers primarily to mechanical engineering, designed to ensure the technological progress of all sectors of the national economy. The fulfilment of this requirement is ensured not only through the simple quantitative growth of production (new capital construction, increased labor force, modernization of obsolete equipment and the creation of a new one), but also through the better use of existing equipment, good organization of labor, the introduction of advanced technology, the dissemination of best practices and the use of progressive equipment.

The intensification of production in mechanical engineering is associated with the modernization of production facilities based on the application of the latest achievements in science and technology. Technical re-equipment, preparation of production of new types of mechanical engineering products and modernization of production facilities inevitably include the processes of designing technological equipment and their manufacture.

In mechanical engineering, in the total volume of technological equipment, about 50% are machine tools. The use of machine tools allows:

reliably base and secure the machined part with preservation of its stiffness during machining;

ensure stable high quality of machined parts with minimum dependence of quality on qualification of the worker;

increase productivity and facilitate working conditions as a result of the mechanization of devices;

expansion of technological capabilities of used equipment.

Comparative analysis of calculation of accuracy of the designed accessory with the tolerance specified in the drawing

The error of the accessory is less than the specified accuracy of the ⌀54H10+0.12 size processing, which indicates the possibility of using a special accessory in this process.
