LIST OF LITERATURE

Summary

The theme of this course project is the design of a given assembly of a horizontal milling-drilling-boring machine. The course work is based on theoretical knowledge obtained at lectures and in the study of literature, as well as on the practical skills of the laboratory workshop. The present work contains a calculation explanatory note with a volume of 22 sheets containing analysis of the initial data, selection of the optimal layout of a given machine assembly, calculation of cutting modes using standard calculation methods, kinematic calculation, selection of an electric motor, calculation of SHS for stiffness, strength, vibration resistance, calculation of the fixing force, as well as a graphical part consisting of annexes to this work.

Introduction

Solving the problems of designing the components and components of the machine system are the main part of the object "Metal Cutting Machines." This course project helps to build the skills of independently solving problems related to the development and design of machine system units with all the necessary intermediate calculations and drawing up the necessary set of documents, as well as to find the most optimal solution to the assigned design task, based on the initial data of the technological system .
