2. INTRODUCTION
Manufacturing is the
backbone of industrialized
nation.
Derived from Latin word
‘manufactus’,means made by
hand.
It implies making of goods or
articles and providing
services to meet the needs of

3. PROCESS PLANNING
Selection of production,
Establishing the efficient sequence of
operation
Determination of changes in form
Calculation of the machining time
Required skill of the operator
Work at minimum cost and maximum
productivity.

4. •Human-machine system is a
system in which the functions of a
human operator (or a group of
operators) and a machine are
integrated.
•A system as a single entity that
interact with external environment.

5. CONCEPTUAL FRAMEWORK FOR
MAN-MACHINE SYSTEM
INFORMATION STORAGE
INPUT SENSING INFORMATION EFFECTOR OUTPUT
PROCESSING
INFORMATION FEEDBACK

8. MECHANIZATION AND
AUTOMATION
Mechanization means something is done or
operated by machinery.
Extensions of mechanization of theproduction
process is termed as automation.

9. COMPUTER AIDED
MANUFACTURING (CAM)
Implies manufacturing itself ,aided or controlled
by computers.
ADVANTAGES OF CAM
1. Greater design freedom
2. Increased productivity
3. Greater operating flexibility
4. Shorter lead time

10. COMPUTER INTEGRATED
MANUFACTURING (CIM) SYSTEM
The integration of CAD (computer
aided design) and CAM (computer aided
manufacturing) systems is called
computer integrated manufacturing
(IM).
CAD + CAM CIM SYSTEM

11. HUMAN –MACHINE
INTERFACE
The way in which man and
machine are inter co-ordinated.
Eg:man’s eye sight augmented by
using microscopes,telescopes …

12. CONCLUSION
For better productivity man –
machine interface is needed.
