DESIGN: It is essentially a decision-making process. If we have a problem we will find a solution. In other words to formulate a plan to satisfy a particular need and to create something with physical quantity.
MACHINE DESIGN:
Generally, the machine is a combination of various elements arranged to work together to serve a specific purpose. Machine design includes designing the elements and arranging the elements optimally to serve the need.
TYPES OF DESIGN:
Adaptive Design
Development Design
New Design
PHASES OF DESIGN:
There are three types of standards used in the design:
International standards organisation (I.S.O)
National standards, such as I.S (Bureau of Indian Standards), D.I.N (Dutch International Number, German), A.I.S.I or S.A.E (American Iron and Steel Institute, USA), B.S (U.K) standards and J.I.S (Japanese Standards).
Company standards for use in a particular company or a group of sister concerns like aircraft and ship-building industries manufacture their products with their own standard without adopting the general standard parts. This type of individual plant standardisation is known as Normalisation.
MATERIALS AND THEIR PROPERTIES:
Selection of proper material for the machine component is one of the most important steps in the process of machine design. The best material is one which will serve the designed objective at minimum cost. Selection of material by trial and error method. While selecting the material to follow the factors
