Comprehensive study material for ITI technical trades, including Fitter Electrician and others. Covers NIMI pattern theory, workshop practicals, safety standards, and industrial manufacturing processes.
Industrial engineering is a representative of the production. It deals with the optimization of complex processes or systems. It is a branch of engineering that is concerned with the development, improvement, money, knowledge, information, equipment, energy, materials, analysis, and synthesis. For industrial engineers, some technical terms are used such as work-study, method study, time study, … Read more
In workshops and industries, different types of machines are being used to give the required output. By the movement of two mating parts of a machine, friction is produced due to which, some amount of heat is generated and it also affects the efficiency of the machine. So, a process called lubrication comes into action … Read more
Springs devices are compressible and expandable up to a certain limit and store mechanical energy because of their elasticity. In a vehicle suspension, when the wheel meets an obstacle, the springing allows movement of the wheel over the obstacle and thereafter returns the wheel to its normal position, all of these are done by the … Read more
All types of machines require power to reach working conditions and the elements, which are used to transfer these powers are known as elements of power transmission. These elements are also useful in transferring the rotatory motion generated by the machine (prime mover) to the different parts of a machine. In the workshops and industries, … Read more
Metals are to be surface-finished to obtain a smooth and finished surface. Smoothing of the surface is done in various ways such as lapping, honing, grinding, reaming, etc. It has many advantages but one major disadvantage is that it is highly porn to corrosion and get rust easily. So, to protect the finished surface from … Read more
Aluminium is a kind of non-ferrous metal such as a metal that does not contain any iron contents. Non-ferrous metals are non-magnetic and resistant to corrosion. They have softness, fusibility, and ease of casting and also have special electrical properties and lower melting points. Some examples of non-ferrous metals are aluminum, copper, lead, tin, zinc, … Read more
A device, which is used for transmitting water, oil, steam, etc., from one place to another is called a pipe. The system of pipes and tube fitting is known as plumbing. It deals with the laying of pipelines for the transportation of the fluids. Plumbing is a system, that deals with pipes, drains fittings, valves, … Read more
Whenever a cutting operation is done on a job, it experiences different types of loads (forces) in different directions. These loads tend to move the job and cutting tool from its original position which results in a decrease in accuracy or dimensional defect of the prepared job. So, it is important that the job should … Read more
We know about the many engineering components that have the internal toughness to protect them from any impact. e.g., Gear, cam, shaft, etc. Case hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft. Thus, forming a thin layer of harder metal is called … Read more
The process of heating and cooling for changing the structure of metal or alloy and thus obtaining the required properties is called heat treatment. It can also be said as a process of heating and cooling of ferrous metals especially various kinds of steels in which some special properties such as softness, hardness, tensile strength, … Read more
