03 Workshop Practices Questions for Interviews

1. What is the purpose of a lathe machine?
• A lathe machine is used for shaping and machining cylindrical workpieces.
2. Explain the working principle of a milling machine.
• A milling machine uses a rotating cutter to remove material from a workpiece, creating complex shapes and profiles.
3. What are the different types of welding processes?
• The different types of welding processes include gas welding, arc welding, and spot welding.
4. How does a gas welding process work?
• In gas welding, a flame is used to heat the workpiece and the filler material, which are then fused together to form a joint.
5. What are the safety precautions to be taken while working in a workshop?
• Safety precautions in a workshop include wearing appropriate protective gear, using tools and machines correctly, and maintaining a clean and organized work area.
6. Explain the working principle of a shaper machine.
• A shaper machine uses a reciprocating cutting tool to remove material from a workpiece, creating flat surfaces and straight edges.
7. What is the difference between a drilling machine and a milling machine?
• A drilling machine is used to create holes in a workpiece, while a milling machine is used to remove material from a workpiece.
8. How is a gear cut in a gear shaping machine?
• In a gear shaping machine, a rotating cutter is used to gradually shape the teeth of a gear.
9. What are the different types of cutting tools used in a lathe machine?
• The different types of cutting tools used in a lathe machine include turning tools, boring tools, and threading tools.
10. Explain the working principle of a hydraulic press.
• A hydraulic press uses a fluid-filled cylinder to generate a large amount of force, which is then used to compress or shape a workpiece.
11. What is the purpose of a grinding machine?
• A grinding machine is used to remove small amounts of material from a workpiece, creating a smooth surface finish.
12. How is a thread cut in a lathe machine?
• A thread is cut in a lathe machine by using a threading tool to gradually shape the workpiece.
13. What are the different types of measuring instruments used in a workshop?
• The different types of measuring instruments used in a workshop include calipers, micrometers, and dial indicators.
14. Explain the working principle of a power hacksaw machine.
• A power hacksaw machine uses a reciprocating blade to cut through a workpiece, powered by an electric motor.
15. What is the difference between a bench vice and a pipe vice?
• A bench vice is used to hold a workpiece in place on a workbench, while a pipe vice is used to hold pipes or other cylindrical objects.
16. How is a sheet metal bent in a bending machine?
• A sheet metal is bent in a bending machine by applying force to the workpiece, causing it to deform and create a desired angle or shape.
17. What are the different types of files used in a workshop?
