b) Feed Gear box: Limiting Transmission

Ratio of Feed Gear Box,

Design Case Study of Feed Gear Box

(with Gear Cone & Sliding Key) for Drilling

Machine, Classification of Feed Gear Boxes,

Study of Application of Norton’s &

Meander’s Mechanism for Thread Cutting

4) Step less Drives

Design of Machine Tool Structure

Function & Requirement of Machine Tool

Structure, Design Criteria from Strength

& Stiffness considerations, Concept of

Unit Rigidity, Unit Strength under

Tension, Unit Strength under Torsion &

Unit Strength under Bending for

Material of Machine Tool Structures,

Compare Steel & Cast Iron on the basis

of Material Properties, Manufacturing

Problems and Economy, Role of Static &

Dynamic Stiffness in the design of

elements of machine tools.

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.

Comparison of Design & stiffness of

Hydrodynamic, Hydrostatic & Aerostatic

Slideways,

Design of Antifriction Guideway,

Concept of Combination Guideways

Design of Power Screws

Design of Sliding friction Power Screw

for Wear Resistance, Strength,

Stiffness, & Buckling Stability.

Design of Rolling friction Power Screw

for Strength under static loading,

Strength under cyclic loading, &

Stiffness

 

Design of Spindle

Function & Requirements of Spindle

Units, their Materials,

Effect of Machine Tool Compliance on

Machining accuracy

Design of Spindle for Bending Stiffness :

Deflection of Spindle Axis due to

a)Bending, b) - due to Compliance

of Spindle Supports, c) - due to

Compliance of the Tapered Joint

Optimum Spacing between Spindle

Supports

Permissible Deflection & Design for

stiffness: Additional Check for Strength

like Additional Supports, Location of

Bearings and Drive elements, Balancing

Design of Spindle Supports

Requirements of Spindle Supports

Features of Anti-friction Bearings, Load

bearing abilities of Ball & Roller

Bearings. Parameters which asses the

viability of combination of roller & Ball &

Roller Bearings in Spindle Units.

Preloading of Anti Friction Bearing & its

method

Design of Sliding Bearings: Sleeve,
