(402051): Machine Tool Design (Elective II)<br />
Teaching Scheme<br />
Lectures: 4 Hrs/Week<br />
Examination Scheme<br />
Paper: 100 Marks<br />
1. Introduction:<br />
Trend in designing machine tools, classification of various machine tools-general<br />
purpose, special purpose, NC-CNC on the basis of kinematics.<br />
2. Drives:<br />
Considerations in designing drives based on continuous or intermittent<br />
requirements of power, type and selection of motor for the drive, regulation and<br />
range of speed based on preferred number series/geometric progression, design of<br />
head stock gear box for spindle drive using ray diagram, structure diagram, nodal<br />
optimisation while designing compact gearbox.<br />
3. Stepless Regulation:<br />
Electromechanical System of regulation, frictrion, pressure and ball variations,<br />
P.I.V. drive (Kopp. Variator), Epicyclic drive.<br />
4. Elements of Machine Tools:<br />
Design of-beds, slideways, carriage, tables of lathes, milling machines based on<br />
force, frictional behaviour and different types of lubrication system. Design of<br />
Power Screws-sliding as well as rolling friction spindle units, supports for
