(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
