To makes the students understand the concepts & broad principles of contents of the course

2. Develop conceptual framework of the course

3.

Aim is to provide insight of the subject

4.

Sensitizes the students of the importance of course in real life environment

Design of Guide ways

Function & Types of Guideways, Types

of Slideways & Antifriction Ways,

Functional features of Slideways, its

Shapes & Materials, Methods of

adjusting Clearance, Design Criteria

(Wear Resistance & Stiffness) and

Calculations for Slideways operating

under semi liquid friction condition,

‘Stick Slip’ phenomena affects accuracy

of setting & working motions.
