Introduction Mechatronics is synergistic integration of mechanical
engineering, electronics and intelligent computer control in design and manufacture of products and processes
What CAD/CAM/CAD ?CAD: Computer-Aided Design
CAM: Computer-Aided ManufacturingCAE: Computer-Aided Engineering
CAD/CAM/CAE softwareCAD – 2D drafting
AutoCAD, TwinCAD, etc.CAD – Solid modeling
Solid Edge, SolidWorks, Mechanical Desktop(MDT), etc.
CAM SOLIDCAM, SURFCAM, MasterCAM,
SmartCAM, etc.CAE
ANSYS, ABAQUS, NASTRAN, ADAMS, MOLDFLOW, etc.

Microcontroller
CPUA single chip
Microprocessor CPU is stand-alone,
RAM, ROM, I/O, timer are separate
designer can decide on the amount of ROM, RAM and I/O ports.

Microcontroller• CPU, RAM, ROM, I/O
and timer are all on a single chip
• fix amount of on-chip ROM, RAM, I/O ports
• for applications in which cost, power and space are critical
• single-purpose

PC-based Measurement and Control
Sensors and ActuatorsSensor A device that converts an environmental
condition into an electrical signal.Actuator A device that converts a control signal
(usually electrical) into mechanical action (motion).
(Taken together, sensors, actuators, controllers, and power supply form
the basic elements of a control system.)
The Following Special Formulation is Offered
Mechatronics studies synergistic fusion of precise
mechatronical units, electronic, electro technical and computer components
for the purpose of designing and manufacturing qualitatively new
modules, systems, machines and complexes of machines
with intellectual control of their functional movements
Comments to the DefinitionMechatronics studies special conceptual approach to
construction of machines.The definition emphasizes synergetic character of
components’ integration in mechatronic objects. Integrated mechatronic components are always
chosen at the designing stage.Methods of parallel designing serve as
methodological basis for Mechatronic Systems (MS) development.
The main objects that mechatronics studies are mechatronic modules.
MS are intended to perform a set movement.In MS methods of advanced intelligent control are
used to secure high quality in performing precise movements.
Principles of Construction MS
Generalized Scheme of Machine with Computer Control of Movement
The structure of a traditional machine
e.g.: cutting forces for machining processes, contact forces and moments of forces at assembly, reactive force of the liquid jet at hydraulic cutting
determ
non-determ
Computer Control Device Basic FunctionsControl of mechanical movement process
on-line with current sensor data analysis.Arrangements to control MS functional
movements. Interaction with operator via human-
machine interface off-line and on-line interaction at the moment of MS movement.
Data exchange between peripheral devices, sensors and other devices of the system.
The Core of Mechatronic Approach
At the stage of designing one interface, as a separate device, is excluded out of a traditional structure, but physical essence of transformation carried out by this module is kept.
in other words
It consists in integrating of components probably of different physical nature into a uniform functional module.
Basic Advantages in Comparison with Traditional Means of Automation rather low cost;ability to perform complicated and precise
movements (of high quality);high reliability, durability and noise
immunity;constructive compactness of modules;improved overall dimension and dynamic
characteristics of machines;opportunity to rebuild functional modules

Requirements of the World Market
in the Considered AreaStandard ISO 9000;Necessity for active introduction of forms and
methods of international engineering and putting new technologies into practice;
Increasing role of small and average industrial enterprises in economy owing to their ability to quick and flexible reaction to changing requirements of the market;
Intellectualization of mechanical movement control systems and technological functions of modern machines.
Fundamental Problems Structural integration of mechanical,
electronic and information departments into a uniform creative staff;
Education and training of engineers specialized in mechatronics and managers able to organize integration and supervise work of strictly specialized experts with different qualifications;
Integration of information technologies from various scientific and technical fields into a uniform toolkit to provide computer support of mechatronic problems;
Standardization and unification of all used elements and processes at designing and manufacturing MS. [email protected]
Levels of Mechatronic Systems’ Integration
conveyors, rotary tables,auxiliary manipulators
The First Level
Levels of Mechatronic Systems’ Integration
operated power machines (turbines and generators),
machine tools and industrial robots with numerical program management
The Second Level
Levels of Mechatronic Systems’ Integration
Synthesis of new precise, information and measuring high technologies gives a basis for designing and producing intellectual mechatronic modules and systems.
The Third Level
Career Paths in Mechatronics mechatronics is seen as a prime career
path for mechanical engineers of the future;
mechanical engineers with a mechatronics background will have a better chance of becoming managers;
classically trained mechanical engineers will run the risk of being left out of the interesting work.
