MACHINE DESIGN

MACHINE DESIGN

Machine design is defined as the use of scientific principle technical information & imagination in the description of a machine or a mechanical system to perform specific function with maximum economy and efficiency .This definition of machine design contains following important features .

1. A designer uses principle of basic engineering sciences such as physics mathematics , statics & dynamics , thermodynamics and heat transfer , vibration and fluid mechanics ,Some of the example of these principle are 
1. D' Alembert's principle 
2. Carnot cycle 
3. Bernoulli's principle
4. Newton's laws of motion 


2. The designer has technical information basic element of machine. These element in clude fastening devices ,chain belt and gear drivers bearing ,oil seals and gaskets ,springs  Shaft ,keys .A machine is a combination of these basic element .The designer knows the relative adavatange & disadavantages  of these basic element & their suitability in different application .


3. The designer uses his skill and imaginatioin to produce a configuration ,which is a combination of these basic element .However this combination is unique and different part of constructing a proper configurartion is creative in nature .



Machine design  is the creation of plans for machine  to perform the desired function. 

Basic procedure of machine design 

The basic procedure of machine  consist of a step by step approch from given specification about the function requirement of a product .

1. Market survey 

2. Define specification of product 

3. Study alternative mechanisms for product & select proper mechanism 

4. prepare general layout of configuration 

5.Design individual components 

6. prepare assembly and detail drawing
