According to the 26th UN Climate Change Conference of the Parties (COP26) held in Glasgow in 2021, the countries are aiming to secure a global net-zero by mid-century. As mechanical engineers in 2022, it is our responsibility to contribute to society for a better future. Because if we do not work towards it, there might be no future to look at.
There are many ways to achieve global net-zero, but today we will ..read more

Chips are a byproduct of any machining or cutting process.
In the process of machining when the tool is performing a cutting operation, e.g. turning, then some material from the workpiece is gradually removed and the desired profile is created. The material which is getting removed is nothing but the mach ..read more

Introduction
The heat treatment processes are done on the metals to achieve certain properties or characteristics for a particular metal. One might want to achieve very strong or brittle or conductive or all of them. Depending on the applications one can use different heat treatment processes.
Different heat treatment processes can be achieved by varying the time of heating, holding at a temperature, rate of cooling, cooling agent, etc.
The microstructure of the metal is differen ..read more

A short recap of the last article is also presented here as follows: The iron-iron carbide diagram is a diagram between iron and carbon at different temperatures, compositions, and phases of iron. There are 3 horizontal lines at 727 deg, 910 deg, and 1147 deg Celcius ..read more

What are the different types of gear assemblies?
Law of Gearing
The common normal at the point of contact between a pair of teeth must always pass through the pitch point for all mating gear positions, according to the law of gearing. The design of the gear profile is based on this law. This is a must for the two gears to function properly.
The angular velocity between two mating gears always remains constant.
Therefore, from the Law of gearing we can derive the relationship as:
where w is angular velocity of gear, n is the gear speed, d is the pitch diameter of the gear,
T is number of teeth ..read more
