In the introduction of Machine Design, we take a look at its definition first.

”Machine design is a topic of study in which students learn to design machine parts using their whole knowledge and expertise in the field of mechanical engineering”

It is the creation of new and better machines and improving the existing ones. A new or better machine is one that is more economical in the overall cost of production and operation. The process of design is a long and time-consuming one. To design a machine or its components, it is good to have knowledge about Mathematics, Mechanics of Materials, Theory of Machines, and Engineering drawing.

Objectives Of Design

  • Design For Strength
  • Design For Function
  • Design For Manufacturing Process
  • Design For Safety
  • Design For Look And Comfort

Design for strength

Safety comes first; therefore the part that is developed should be robust enough to withstand the forces that will be applied to it during its service. It was also necessary to be able to withstand any possible occurrences during service as a result of increased load for whatever cause.

Design for function

Every portion of a machine serves a specific purpose in the machine. The designer should guarantee that the part to be created performs its purpose satisfactorily.

Design for manufacturing process

Designers must alter their products in light of the available production methods, as well as their limits and strengths. The design of a machined item differs from that of casting.

Design for safety

The designer must verify that the part he is developing is safe to use. And no danger to life or health will result from its operation.

Design for lock and comfort

It is a secondary aim of the designer to create a portion that is both comfortable for the user and visually appealing.

Types of Machine Design

  • Development design
  • Adaptive design
  • New design

Process of Machine design

  • Identify the needs
  • Select mechanism
  • Analyze the force
  • Select appropriate material
  • Design the elements
  • Modify the design and make detail drawing
  • Production of product
