Siddhalaxmi Engineering Industries Intern Interview Questions, Process, and Tips

Machining processes involve removing material from a workpiece to create a desired shape or finish.

• Turning: Rotating the workpiece while a cutting tool removes material.

• Milling: Using a rotating cutter to remove material from the workpiece.

• Drilling: Creating holes in the workpiece using a rotating drill bit.

• Grinding: Using an abrasive wheel to remove material and create a smooth surface.

• Electrical Discharge Machining (...read more

Types of casting include sand casting, investment casting, die casting, and more.

• Sand casting involves pouring molten metal into a sand mold

• Investment casting uses a wax pattern that is melted away

• Die casting uses a metal mold to create parts with high accuracy

• Other types include centrifugal casting, continuous casting, and more

Types of stress include acute stress, episodic acute stress, and chronic stress.

• Acute stress is short-term stress triggered by a specific event or situation.

• Episodic acute stress is when someone experiences frequent episodes of acute stress.

• Chronic stress is long-term stress that persists over an extended period of time.

• Examples: Acute stress from a deadline at work, episodic acute stress from juggling multiple respons...read more

Hydraulic systems use liquid to transmit power, while pneumatic systems use gas.

• Hydraulic systems use incompressible fluids like oil, while pneumatic systems use compressible gases like air

• Hydraulic systems are typically used in heavy machinery like excavators and hydraulic brakes in cars

• Pneumatic systems are commonly found in tools like pneumatic drills and air brakes in trucks

Heat treatment is a process used to alter the physical and sometimes chemical properties of a material through heating and cooling.

• Heat treatment involves heating a material to a specific temperature, holding it at that temperature for a certain amount of time, and then cooling it at a controlled rate.

• The purpose of heat treatment is to improve the material's hardness, strength, toughness, ductility, and other properti...read more

Types of heat transfer include conduction, convection, and radiation, each with unique characteristics.

• Conduction: Heat transfer through direct contact between particles, such as a metal spoon heating up in a hot drink.

• Convection: Heat transfer through the movement of fluids or gases, like boiling water in a pot.

• Radiation: Heat transfer through electromagnetic waves, such as the warmth felt from the sun.
