Automation
Prof. Jeetendra Dhamone
The technique of making an apparatus, a process, or a system
operate automatically.
The creation and application of technology to monitor and
control the production and delivery of products and services.
Automation is the creation and application of technologies to
produce and deliver goods and services with minimal human
intervention. The implementation of automation technologies,
techniques and processes improve the efficiency, reliability,
and/or speed of many tasks that were previously performed by
humans.
Automation used in
 Manufacturing
 Transport
 Utilities
 Defense
 Facilities
 Operations and lately
 Information technology.

UNIT I CIM
Reasons for Automation
Mob. No: 8951834155
Reasons for Automation
 Increased productivity due competition
 High cost of labour
 Labour shortage
 Trend of labour toward the sector
 Safety
 High cost of raw materials
 Improved product quality
 Reduced manufacturing lead time
 Reduction of in process inventory
 High cost of not automation
 Due to Industrialization and globalization the global competition
escalates which causes increase the demand the stoner of productivity
& quality.
 Automation system required less Labour hence increasing cost of
Labour don`t of heat on it
 Many Advanced nations, there has been a shortage of Labour
 There are some social & institutional forces Labour toward the
service sector.
 Automation delaminates the human role, work is made safer.
 The high cost of raw materials in manufacturing results in the need
for greater efficiency in using there materials
 Automated operation not only produces parts of faster rates but they
produce parts with greater consistency and conformity to quality.
 For automation allows the manufacturer to reduce the time between
custom order and product delivery.
 Holiday large inventories of work in process represent a significant
cost to the manufacturer because it ties up capital.

UNIT I CIM
Type of Automation
Mob. No: 8951834155
Automation systems are classed into three different types of
automation:
 Fixed automation
 Programmable automation
 Flexible automation

UNIT I CIM
Fixed Automation
Mob. No: 8951834155
 The process of manufacturing fixed by the way it is configured,
following a fixed sequence of automated processes.
 An example of this is flow production
 Hard automation
 Fixed automation can be expensive to set up initially due to the
equipment required, but in return, it provides high production rates.
 High demand and generic products that require no change.
 Coca cola continues to use this automation in their factories.
 Advantages of fixed automation include:
 High levels of production
 Consistent quality in production
 Low cost per unit produced
 Disadvantages of fixed automation include:
 High initial cost
 Difficult to accommodate changes

UNIT I CIM
Programmable Automation
Mob. No: 8951834155
 The production equipment and automation to be altered to
changing needs
 Controlling the automation through a program
 Low to medium levels of production
 Batch production.
 Used by factories who make different variants of foods.
 If the product needs changing, it simply needs to be
reprogrammed.
 Advantages include:
 Flexibility to change products if needed
 Suitable if batch production is required
 Disadvantages include:
 Expensive for equipment
 Lower production levels
 Often time-consuming to change products

UNIT I CIM
Flexible Automation
Mob. No: 8951834155
 Flexible automation, also known as “soft automation”, is
similar to programmable automation, although a little more
complicated. Essentially, flexible automation enables the
production of different types of products without losing time
when reprogramming.
 A flexible automation system can produce various
combinations of products efficiently without having to
separate them into different batches, as required in batch
production. This type of automation tends to have medium
levels of production.
 Advantages include:
 Flexibility of products
 No time lost with new changes to production
 Disadvantages include:
 High custom machinery/automation cost
 Higher cost per unit
Flexible automation systems consist of the following:
 Part processing machines: CNC machining equipment
carries out a portion of these processes, with inspection
and other automated work stations used in combination.
 Material-handling system: Conveyancing and other
systems move parts from one area along the production
line to another, with robots generally used for the
loading and unloading of product.
 Central computer control system: Communications that
come from this central controller provide component
routing information and adjust timing within the
material-handling system while also coordinating the
operational processes of these machines.
 Human labor: While these systems are based around
automation, engineering this flexibility still requires
humans to manage, repair, maintain and alter procedures
when necessary.

UNIT I CIM
Functions of Automation in manufacturing
Mob. No: 8951834155
The certain basic functions as –
 Processing
 Assembly
 Material handling & storage
 Inspection & Testing
 Control
Processing: It is the operations which transforms the
product from one state of completion into a more
advanced state of completion.
Into one of the following four categories.
 Basic processes
 Secondary processes
 Finishing operations
 Operations to enhance physical properties
Assembly operation :-
 In it the distinguishing feature is that two or more separate
components are joined together.
 It included mechanical fostering operations, which make use
of screws nuts, rivets and so on, and going processes such as
welding, brazing & soldering.
Material handling and storage :-
 A means of moving and storing materials between the
processing and assembly operations must be provided.
 Material spend move time being moved and stored than
being processed.
 Mostly the cost would be required for handling, moving &
storing of materials.
Inspection & Testing :-
 It is purpose of inspection is to determine the product meets
the established design standards & specifications.
