Mechatronics in manufacturing
Mechatronics in Products
• The word "mechatronics" was first coined by Mr.
Tetsuro Moria, a senior engineer of a Japanese
company, Yaskawa, in 1969.
• Mechatronics may alternatively be referred to as
"electromechanical systems," or as "smart
which, combined, make possible the generation
of simpler, more economical, reliable and
• Mechatronics is “the synergistic integration of
Mechanical Engineering with Electronics and
intelligent control algorithms in the design
and manufacture of products process”.
• The Prime Example – Industrial Robots.
• Mechatronics can also be termed as
replacement of mechanics with electronics or
enhance mechanics with electronics. Eg- Fuel
Evolution of Mechatronics
• Primary Level : Integrates electrical signaling
with mechanical action at the basic control
level for e.g.fluid valves and relay switches
• Secondary Level : Integrates microelectronics
into electrically controlled devices for e.g.
cassette tape player.
Evolution of Mechatronics
• Tertiary Level : Incorporates advanced control
strategy using microelectronics, microprocessors
and other application specific integrated circuits
for e.g. microprocessor based electrical motor
used for actuation purpose in robots.
• Quaternary Level : This level attempts to improve
smartness a step ahead
intelligence ( artificial neural network and fuzzy
logic ) and fault detection and isolation ( F.D.I.)
capability into the system.
• Marketing: Signifies market research, identification of
user needs, information analysis and formulation of
development, production planning, material handling
and quality control.
• Design: The concentration is on studying fundamental
aspects of sensors, actuators, control and integration
methods. Broadly the core of a mechatronics system
incorporates Mechanical,Electronics, Control and
Information system engineering.
Mechatronics: products and systems in
• Computer numerical control (CNC) machines
• Tool monitoring systems
• Advanced manufacturing systems
– a) Flexible manufacturing system (FMS)
– b) Computer integrated manufacturing (CIM)
Computer numerical control (CNC)
• CNC machine is the best and basic example of
application of Mechatronics in manufacturing
• Mechatronics based automation in these machine
tools has greatly reduced the human intervention in
manufacturing operation and improved the process
efficiency and product quality.
• CNC is the operation of a machine tool by a series of
coded instructions consisting of numbers, letters of the
alphabets, and symbols which the machine control unit
Tool monitoring systems
• Tool wear is a critical factor in productivity of a
Flexible Manufacturing Systems
• Nowadays customers are demanding a wide
variety of products.
• To satisfy this demand, the manufacturers’
“production” concept has moved away from
“mass” to small “batch” type of production.
• Batch production offers more flexibility in product
• FMS is a manufacturing cell or system consisting
of one or more CNC machines, connected by
automated material handling system, and all
operated under the control of a central computer.
Benefits of an FMS
Flexibility to change part variety
Higher machine utilization
High product quality
Better control over production
Minimally manned operation
Easier to expand
• Just-in-time (JIT) manufacturing is a
production model in which items are created
to meet demand, not created in surplus or in
advance of need. The purpose of JIT
production is to avoid the waste associated
• Computer-integrated manufacturing (CIM) is
the manufacturing approach of using
computers to control the entire production
