FMEA stands for Failure Mode and Effects Analysis. It is a systematic approach to identifying and preventing potential failures in a product or process.
FMEA is a risk assessment tool used in engineering and manufacturing.
It involves identifying potential failure modes, their causes, and the effects of those failures.
The goal is to prioritize and address the most critical failure modes to prevent them from occurring.
FME...

Thumb rules for sheet metal design include minimum bend radius, hole spacing, and material thickness considerations.
Minimum bend radius should be at least equal to the material thickness to avoid cracking
Hole spacing should be at least 2 times the material thickness to prevent distortion
Material thickness should be chosen based on the application and required strength
Avoid sharp corners to reduce stress concentrations

I applied via Naukri.com and was interviewed before Feb 2023. There were 2 interview rounds.
Aptitude test is conducted by organization to know the problem solving ability of candidate.
Different types of connections in steel structures include welded connections, bolted connections, and riveted connections.
Welded connections involve joining steel members by welding them together.
Bolted connections use bolts and nuts to connect steel members.
Riveted connections use rivets to connect steel members.
Other types of connections include pinned connections and moment-resisting connections.

Gear ratio is the ratio of the number of teeth on the driving gear to the number of teeth on the driven gear.
Gear ratio determines the speed and torque relationship between two gears.
It is calculated by dividing the number of teeth on the driving gear by the number of teeth on the driven gear.
A gear ratio greater than 1 indicates a reduction in speed and an increase in torque, while a ratio less than 1 indicates an inc...
The symbol of first angle method is a triangle with the vertex pointing downwards. The symbol of third angle method is a triangle with the vertex pointing upwards.
First angle method is commonly used in Europe and Asia while third angle method is commonly used in North America.
In first angle method, the object is placed in the first quadrant while in third angle method, the object is placed in the third quadrant.
The sym...
The K factor is a value used in sheet metal design to determine the amount of springback that occurs during bending.
The K factor is a ratio that relates the neutral axis to the material thickness.
It is used to calculate the bend allowance and bend deduction in sheet metal bending operations.
A higher K factor indicates more springback, while a lower K factor indicates less springback.
Different materials and bending proc...
Spring back effect is the tendency of a material to return to its original shape after being deformed.
Spring back effect occurs when a material is bent or stretched and then released, causing it to return to its original shape.
It is commonly observed in materials like metals and polymers.
The amount of spring back depends on the material's elasticity and the magnitude of the deformation.
Spring back can be a desirable or...
Machining operations involve using various tools and techniques to shape and cut raw materials into the desired shape and size.
The job may involve using lathes, milling machines, grinders, or other specialized equipment.
The machinist must carefully measure and mark the material before cutting or shaping it.
The machinist may need to use different cutting tools or techniques depending on the material being worked on.

There are various types of gearboxes including spur, helical, bevel, worm, planetary, and cycloidal.
Spur gearboxes have straight teeth and are the simplest type.
Helical gearboxes have angled teeth and are quieter than spur gearboxes.
Bevel gearboxes are used for changing the direction of power transmission.
Worm gearboxes have a screw-like gear and are used for high reduction ratios.
Planetary gearboxes have multiple gear...
I applied via Recruitment Consultant and was interviewed before Oct 2019. There was 1 interview round.
RPM can be changed by adjusting the speed of the motor or by using a gearbox.
Adjust the voltage or frequency of the power supply to the motor
Use a variable frequency drive to control the motor speed
Use a gearbox to change the speed of the output shaft
Change the size of the pulleys or gears in the system
Use a different motor with a different speed rating
Gears can be made of various materials depending on the application and requirements.
Common materials include steel, cast iron, bronze, and plastic.
Steel gears are strong and durable, but can be noisy.
Cast iron gears are also strong and durable, but are quieter than steel.
Bronze gears are used in applications where low noise and high strength are required.
Plastic gears are lightweight and can be used in applications wh...
There are numerous materials used in engineering, each with unique properties and applications.
Metals: strong and durable, used in construction and machinery
Polymers: lightweight and flexible, used in packaging and consumer goods
Ceramics: heat-resistant and hard, used in electronics and construction
Composites: combination of materials, used in aerospace and sports equipment
Why we use them in specific: based on their pr...
