Summary

The course project on the topic "Technological process of manufacturing the" Hub "part on the subject of the basis of mechanical engineering technology is made on 30 pages, includes 8 tables, 8 drawings, 5 literary sources, specification. The graphic part of the project consists of 4 sheets:

Part - Hub (A3 format)

Process plan (A2 format)

Process adjustment (A2 format)

Process accessory - Rock conductor (A2 frame).

Introduction

This course design presents the development of the manufacturing and processing process of the Hub part.

For development, they determined the type of production, conducted an analysis of the utility purpose of the part, an analysis of the processability of the part design, and chose the method for obtaining the part workpiece .

Then they designed the machining process, selected machines, made a dimensional analysis. Then, for the drill operation, the cutting modes were calculated, the drilling machine model, tool and tool setup were selected.

Conclusion

The course project analyzed the design of the Stupitsa part, its service purpose and the purpose of the unit in which it is installed, also developed the technological process, basing schemes for various operations, and calculated linear dimensions according to the methodology developed at the Department of Engineering Technology by B. S. Mordvinov. The necessary accuracy of design dimensions is ensured.

At operation No. 20 "Drilling," adjustment was designed, equipment and cutting modes were selected. The fixture was designed for clamping force.
