What is Machine Design? Introduction | Process | Purpose

Introduction :

Machine design is the use of scientific principles, technical information and imagination in the description of the machine or any mechanical system to perform a specific function with maximum economy and efficiency.

While any design takes part below features are take care :
  • A designer uses the principle of basics and engineering science.
  • The designer has technical information on the basic elements of a machine.
  • The designer uses his skill and imagination to produce a configuration.
  • The final outcome of the design process consists of the description of the machine.
  • A design is created to satisfy the need of the customer.

The basic procedure of machine design :
  • Market survey
  • Define the specifications of the product
  • Study alternative mechanics for product
  • Prepare the general layout of the configuration
  • Design individual components
  • Prepare assembly 

The Purpose of Machine Design :

The knowledge of machine design helps the designers as follows:
  • To select proper materials and best-suited shapes
  • To calculate the dimensions based on the loads on machines and strength of the material
  • Specify the manufacturing process for the manufacture of the designed component of the machine or the whole machine.

Machine Design is the application of mathematics, kinematics, statics, dynamics, mechanics of materials, engineering materials, mechanical technology of metals and engineering drawing. It also involves the application of other subjects like thermodynamics, electrical theory, hydraulics, engines, turbines, pumps etc. Machine drawing is the integral part of the machine design since all the components or the machines that have been designed should be drawn to manufacture them as per the specifications. Without machine drawing the subject of the machine design is incomplete.
