What is Machine Design Procedure?

We often confuse between design and drawing/drafting. We consider drawing/drafting as a design, but designing is a whole different procedure and in that procedure, there is drafting or drawing.

Machine design refers to creating new machines or improving the existed ones.

Then what are those procedures to design a machine element or new machine or an existed one? So today we are discussing those procedures.

These are the steps/procedure involved in Machine Design.

1. Identifying the need for the Equipment or a Machine
2. Selecting the possible Mechanisms
3. Analysis of Forces
4. Selection of Materials
5. Design of Elements
6. Modification
7. Detailed Drawings
8. Production
9. Quality Checking

Identifying the need for the Equipment or a Machine

First of all, we have to identify the problem in the system. Whether the problem exists or not. Then we have to decide the aim and the purpose of the machine/element to be designed.

Selecting the possible Mechanisms

Identify and analyze the best mechanism and motions which will suit the given machine.

Analysis of Forces

Then analyze the forces acting on the different machine parts which are in motion or stationary

Selection of Materials

After analysis of forces, select proper material with required properties.

Design of Elements

After analyzing forces and selecting material, we have to design every element of the machine to select the proper dimensions to withstand the stresses. The stresses should be below the limit of the permissible stresses of that material. We have to provide the correct factor of safety to every element.

Modification

After the overall design of the machine elements, we have to modify the machine according to the resources and reduce the cost of the overall machine. Because sometimes we design a machine properly by taking every aspect in mind but in the real world we have to take considerations of available resources in the market and the total cost of the machine.

Detailed Drawings

After the modification, we will make drawings of every part, subassembly, and assembly drawings of the machine. Also, we have to take into consideration of the available manufacturing facilities in the market while drawing the parts. After that, we will go for manufacturing.

Production

As per the drawing, components are manufactured in manufacturing units and assembled as per the drawings.

Quality Checking

The machine will then go through quality checking ensuring the good quality and safety of the product.

So, these are the basic design procedure followed while designing any machine or machine elements. We hope you gained some valuable knowledge.
