Forging process involves shaping metal by applying compressive forces using a hammer or press.
Metal is heated to a high temperature to make it more malleable
The metal is then shaped using a hammer or press to apply compressive forces
Forging can be done using different techniques such as open-die forging, closed-die forging, or impression-die forging

There are various types of steel with different chemical compositions, each with unique properties and uses.
Carbon Steel - primarily composed of iron and carbon
Alloy Steel - contains additional elements such as manganese, nickel, and chromium
Stainless Steel - contains at least 10.5% chromium and low carbon content
Tool Steel - high carbon content and additional elements such as tungsten and vanadium
High-Speed Steel - co...
Heat treatment is a process of heating and cooling metals to alter their physical and mechanical properties.
Heat treatment is used to improve the strength, hardness, toughness, and ductility of metals.
It involves heating the metal to a specific temperature and holding it there for a certain amount of time.
The metal is then cooled at a specific rate to achieve the desired properties.
Different types of heat treatment inc...

First angle projection and third angle projection are two different methods used in mechanical drawings to represent a 3D object on a 2D plane.
First angle projection is commonly used in Europe and Asia, while third angle projection is commonly used in North America.
In first angle projection, the object is placed in the first quadrant and the views are projected onto the planes surrounding the object.
In third angle proj...

FMEA is Failure Modes and Effects Analysis used to identify and prioritize potential failures in a process or product.
FMEA involves identifying potential failure modes, their effects, and the likelihood of their occurrence.
To improve a control plan using FMEA, prioritize high-risk failure modes and implement controls to prevent or mitigate them.
Regularly review and update the FMEA and control plan based on new informat...
Failure Mode and Effects Analysis
FMEA stands for Failure Mode and Effects Analysis
It is a systematic method for identifying and preventing potential failures in a design or process
Helps in prioritizing and addressing potential failure modes based on their impact and likelihood
Commonly used in industries such as automotive, aerospace, and manufacturing
Example: Conducting FMEA on a car engine to identify potential failur
