JSW Steel Interview Questions and Answers

Electric motors convert electrical energy into mechanical energy, while electric generators convert mechanical energy into electrical energy.

• Electric motors use electrical energy to create motion, while electric generators use motion to create electrical energy.

• Electric motors have a rotor that spins inside a stator, while electric generators have a rotor that is turned by an external force to produce electricity.

• Examples of electric motors include those used in household app...read more

Production is the process of creating goods or services, while manufacturing is a subset of production that involves the creation of physical goods.

• Production involves both goods and services, while manufacturing is limited to physical goods.

• Production is a broader term that includes manufacturing, while manufacturing is a subset of production.

• Manufacturing involves the use of machinery and tools to create physical goods, while production can involve a variety of processes.

• Ex...read more

Common tools for measuring on a CNC machine include calipers, micrometers, height gauges, and dial indicators.

• Calipers are used for measuring distances between two points on a workpiece.

• Micrometers are used for precise measurements of small distances or thicknesses.

• Height gauges are used for measuring the vertical distance from a reference point to a workpiece.

• Dial indicators are used for measuring small distances or variations in position.

• Other tools may include depth gauges...read more

Hydraulic machines use fluid power to generate, control, and transmit energy.

• Hydraulic machines work by using a liquid, typically oil, to transmit force and motion.

• They operate based on Pascal's law, which states that pressure applied to a confined fluid is transmitted undiminished in every direction.

• Hydraulic machines work on the principle of converting mechanical energy into hydraulic energy and vice versa.

• Examples of hydraulic machines include hydraulic presses, hydraulic ...read more

Poke Yoka, 5S, Kaizen, and Safety are key concepts in lean manufacturing and continuous improvement.

• Poke Yoka focuses on mistake-proofing processes to prevent errors before they occur.

• 5S is a methodology for organizing the workplace to improve efficiency and effectiveness (Sort, Set in order, Shine, Standardize, Sustain).

• Kaizen is the practice of continuous improvement involving all employees in making small changes for the better.

• Safety is a priority in manufacturing to ensu...read more
