Precision engineering is the discipline of manufacturing parts of machines that are required to maintain, measure or follow a path with high precision. It is crucial that the precision parts are made with utmost efficiency and care for the functioning of these machines, as they come in use in several industries that are important to the functioning of human society.
Structural parts like brackets of different designs are used in infrastructure, aerospace and space vehicles such as rockets. Brackets are of use in almost any vehicle. They are used to hold heavy items and prevent damage to other machine parts. In industries like the automobile industry, precision engineered parts make all the difference. More efficiency in a vehicle would require a more accurately manufactured part. Precision engineered parts such as flyweights, crucial to fuel injectors, control the amount of diesel released into the engine when accelerated. Parts like drive pinions are important in helping to turn the wheel’s rotational motion into linear motion so that the vehicle may turn. Well manufactured parts like spindles also aid in the movement of the wheel.
In machines such as an aircraft, the parts that are made need to withstand high and low temperatures, vibrations and speeds. Precision parts such as bearing flanges and brackets aid in this. It is not just parts of a motor that require precision engineering, but even something as commonplace as a seatbelt bezel on an aircraft. For obvious reasons, high precision is required in manufacturing these, too. Precision engineering is highly specialised, and a lot of efficiency and thought goes into producing the smallest parts of the big machines we see at work.
Precision engineering eliminates human error, speeds up production, and reduces waste generated in the process. It ensures reliability of a machine and therefore its sustainability over a period of time. Precision engineered parts are used in a vast array of industries like aerospace, automobile, railways and healthcare, making it crucial to the smooth functioning of society and the further development of civilisation.
