Introduction To Manufacturing Systems

In

this

chapter,

we

consider

how

automation

and

material

handing

technologies

are

synthesized create manufacturing systems. We define a manufacturing system to be a collection of

integrated

equipment

and

human

resources,

whose

function

is

perform

one

or

more

processing

and/or assembly operations on a starting raw material part, or set parts. The integrated equipment

includes

production

machines

and

tools,

material

handling

and

work

positioning

devices,

and

computer systems. Human resources are required either full time or periodically

to keep the

system running. The manufacturing system is where the value-added work is accomplished on the

part

or

product.

The

position

of

the

manufacturing

system

in

the

larger

production

system

is

shown as Figure. 3.1 Examples of manufacturing systems include :

?

One worker tending one machine, which operates on semi- automatic cycle

?

A cluster of semi-automated assembly machine, attended by one worker

?

A full automated assembly machine, periodically attended by a human worker

?

A

group of

automated

machines

working on

automatic

cycles

to

produce

a

family

of

similar parts

?

A team of workers performing assembly operations on a production line

Components of a Manufacturing system

A

manufacturing

system

consists

of

several

components.

In

a

given

system,

these

components usually include:

1)

production machines plus tools, fixtures, and other related hardware;

2)

material handling system

3)

computer systems to coordinate and/or control the above components

4)

human workers

Production Machines

In virtually all modern manufacturing systems,

most of the actual processing or assembly

work is accomplished by machines or with the aid of tools. The machines can be classified as 1)

manually

operate

,

2)

semi- automated

,or

3)fully

automated

,

Manually

operated

machines

are

directed or supervised by a human worker. The machine provides the power for the operation and

the worker provides the control. Conventional machine tools (e. g ,lathes , milling machines ,drill

presses ) fit into this category . The worker must be at the machine continuously.

In manufacturing systems, we use the term workstation to refer to a location in the factory where

some

well-defined

task

operation

is

accomplished

by

an

automated

machine

,

a

worker-and-machine combination , or a worker use hang tools/or portable powered tools. In the

last

there

no

definable

production

machine

at

the

location .

Many

assembly

tasks

are

in

the

category . A given manufacturing system may consist of one or more workstations. A system with

multiple

stations

is

called

a

production

line

,

or

assembly

line

,

or

machine

cell

,or

other

name ,depending on its configuration and function .
