5. Unit 1: Introduction “The name [Mechatronics] was coined by Ko Kikuchi, now president of Yasakawa Electric Co., Chiyoda-Ku, Tokyo.” [ R. Comerford, “Mecha … what?” IEEE Spectrum, 31(8), 46-49, 1994.] “ The word, mechatronics is composed of mecha from mechanics and tronics from electronics. In other words, technologies and developed products will be incorporating electronics more and more into mechanisms, intimately and organically, and making it impossible to tell where one ends and the other begins.” [T. Mori, “Mechatronics,” Yasakawa Internal Trademark Application Memo, 21.131.01, July 12, 1969] Mechatronics Means

7. Mechatronics is the synergistic integration of sensors, actuators, signal conditioning, power electronics, decision and control algorithms, and computer hardware and software to manage complexity, uncertainty, and communication in engineered systems. [engineering.nyu.edu/gk12/amps-cbri/pdf/Intro%20to%20Mechatronics.pdf] Refined Definitions Mechatronics basically refers to mechanical electronic systems and normally described as a synergistic combination of mechanics, electrical, electronics, computer and control which, when combined, make possible the generation of simple, more economic, and reliable systems.

11. 1)As replacement of mechanics with electronics or enhance mechanics with electronics. Mechanical fuel injection systems are now replaced with electronic fuel injection systems. 2) With the help of microelectronics and sensor technology, mechatronics systems are providing high levels of precision and reliability. Possible to move (in x – y plane) the work table of a modern production machine tool in a step of 0.0001 mm. 3) By employment of reprogrammable microcontrollers/microcomputers, it is now easy to add new functions and capabilities to a product or a system.

12. Role of Mechatronics in Design and Manufacturing:- Today’s market is very competitive due to variety of demand of customers as well as higher levels of flexibility in the products. Design and develop a certain product involve a typical risk which manufacturer is facing now a days. Reducing life cycle of product and lead time in manufacturing also demands efficient planning and manufacturing. Mechatronics concurrently employs the different disciplines at the stage of design. Mechanical -Various machines and mechanisms, Product design and development activities, materials and manufacturing resource planning Electrical engineering -Various electric prime movers viz. AC/DC, servo motors and other systems is used. Control engineering-Development of various electronics-based control systems to enhance or replace the mechanics of the mechanical systems. Computer Engineering - Various soft wares to control the control systems; http://nptel.ac.in/courses/112103174/pdf/mod1.pdf

13. Computer Aided Design (CAD) / Computer Aided Analysis (CAE):- Three-dimensional models of products can easily be developed. These models can then be analyzed and can be simulated for their performances. Parameters of simulation can be enriched time to time with the real-life performances of the similar kind of products. Can get approximate idea about performance of the product/system in early stage of design which helps in modification and updating. In traditional design and manufacturing design assessment was carried out after first batch. Role of Mechatronics in Design and Manufacturing:- http://nptel.ac.in/courses/112103174/pdf/mod1.pdf

14. Role of Mechatronics in Design and Manufacturing:- Computer Aided Manufacturing (CAM):-using the design data  Automatic process planning,  Automatic part programming,  Manufacturing resource planning,  Manufacturing targets in terms of quality and quantity with in a stipulated time frame. Mechatronics based automated systems can be deployed to improve efficiency such as automatic inspection and quality assurance,  Automatic packaging,  Record making, and  Automatic dispatch Automation in the machine tools improves the process efficiency and product quality as human intervention is reduced in the machining operation http://nptel.ac.in/courses/112103174/pdf/mod1.pdf

15. Traditional SystemMechatronics system Components are designed using mechanical, hydraulics and pneumatic principles only. Mechanical, electronics, computer technology and control engineering principles are included to design a system. Designs are less flexible.More flexible can change as per requirement. Less accurate.Using microcontrollers and other electronics components system become more accurate. Complicated design for any movementCompact and simple in design. Involves more component and moving parts, increase in weight. Less moving parts with lightweight. Comparison http://nptel.ac.in/courses/112103174/pdf/mod1.pdf
