Machine design and its classifications

Introduction of Machine design

Branch of mechanical engineering/technology which deals with the creation of new and modified(better) machines and improving the existing ones. New and better machine is possible when its overall cost of production and operation is much economical. In machine design it is essential to have the knowledge of strength of material,theroy of machines and workshop technology.

Classifications of machine design.

Machine design can be classified into following types.

1: Adaptive design

In many cases, the designer's work is connected with adaptation of existing design. It is fundamental and basic designing procedure which is required no extra knowledge or skills. In this type of design, designer makes small modification in the existing machine or product.

2: Development design

This type of design requires much more design skills and scientific training to produce a new and modified machine. In this case, designer starts from the the existing designs but finished product can be different from the original one.

3: New design

This is unique kind of designing which requires much more technical ability, creative mind and lots of research. This type of design can only those handle which have these personal qualities.

4: Rational design

This class of design requires the ability of principles of mechanics and mathematical expertise.

5: Empirical design

This type of machine designing procedure requires empirical formulas and past practice of machinery development.

6: Industrial design

This kind of design depends on the production aspects to produce any machine parts used in the industries.
