Introduction

The level of development of mechanical engineering is a determining factor in the development of the entire economic complex of the country. The most important conditions for accelerating the development of the economic complex are increasing labor productivity, increasing production efficiency and improving product quality.

The use of improved machine manufacturing methods is of paramount importance. The quality of the machine, reliability, durability and cost-effectiveness in operation depend not only on the perfection of its design, but also on the technology of its manufacture.

The process engineer is the last in the chain of creating a new machine and its quality largely depends on the volume of its knowledge and experience.

These basic prerequisites define the following important directions of mechanical processing technology development in mechanical engineering.

1 Improving existing and finding new high-performance methods and tools for performing dramatically increased finishing operations in order to improve processing accuracy and reduce their labor intensity.

2 Improvement of existing and finding new high-performance processes for performing semi-finished and finishing operations with metal and abrasive cutting tools.

3 Complex mechanization and automation of technological processes based on the use of automatic lines, automated and floor automated machines, active control tools, fast-acting technological equipment, group methods of processing technologically similar parts.

4 Development of plastic deformation forming processes and application of thin plastic deformation methods for finishing operations.

5 Development of electrophysical and electrochemical processing methods.

Conclusion

As a result of the development of this course project, a complete study of the technological process of obtaining the part in small-scale production conditions was carried out. The most important stage of the technology design is the purpose of the route processing process, the selection of equipment, a cutting tool and a machine tool with a pneumatic drive for drilling the hole. In performing this work, the skills of designing and calculating various elements are obtained, which make it possible to ensure the reliability and durability of the device .
