A jig is a workshop tool used to guide a cutting tool, such as a drill or saw, ensuring precise and repeatable machining. It's often custom-made for specific jobs to improve accuracy and efficiency.
5. What is the main function of a drill press in a workshop?
Answer:
Explanation:
A drill press is a fixed style of drill that may be mounted on a stand or bolted to the floor or workbench. It is used in workshops to drill accurate and precise holes in various materials.
6. What is the purpose of a surface grinder in a workshop?
Answer:
Explanation:
A surface grinder is used to produce a smooth finish on flat surfaces. It involves a rotating abrasive wheel that removes material from the surface of a workpiece to achieve the desired finish.
7. What is the primary use of a bandsaw in a workshop?
Answer:
Explanation:
A bandsaw in a workshop is primarily used for cutting irregular or curved shapes in metal or wood. The continuous band of a toothed metal blade rotated by two or more wheels accomplishes this.
8. What is an anvil typically used for?
Answer:
Explanation:
An anvil is a metalworking tool used as a forging surface. Workpieces are placed on it while they are hammered or shaped, usually in blacksmithing and metalworking tasks.
9. What is the process of using a sharp tool to remove small chips of material from a workpiece called?
Answer:
Explanation:
Chipping is a basic machining process where a sharp tool is used to remove small chips of material from a workpiece. It's often used for shaping and finishing metals and other materials.
10. What is the purpose of a shaper machine in a workshop?
Answer:
Explanation:
A shaper machine is used in workshops to produce flat and angular surfaces. It operates by moving a cutting tool back and forth across a workpiece.
11. What is the function of a vise in a workshop?
Answer:
Explanation:
A vise is a mechanical device used in workshops to securely hold a workpiece in place while it is being worked on. It ensures stability and precision during machining processes.
12. What is the primary advantage of using Computer-Aided Manufacturing (CAM)?
Answer:
Explanation:
CAM offers enhanced precision and consistency in the manufacturing process. It allows for the automation of manufacturing tasks and improved control over production.
13. What is the main purpose of a hydraulic press in a workshop?
Answer:
Explanation:
A hydraulic press uses hydraulic fluid to generate a compressive force. It is commonly used in forging, molding, clinching, blanking, punching, and metal forming operations.
14. What is oxy-acetylene welding?
Answer:
Explanation:
Oxy-acetylene welding is a welding process that uses a mixture of oxygen and acetylene gas to produce a flame hot enough to melt metals. This process is commonly used for welding and cutting.
15. What is the main use of a sandblaster in a workshop?
Answer:
Explanation:
A sandblaster uses a stream of sand propelled by compressed air to clean or prepare surfaces by removing rust, paint, or other coatings. It's an effective tool for surface preparation.
16. What is the purpose of heat treatment in a workshop?
Answer:
Explanation:
Heat treatment is a process used in workshops to alter the physical and chemical properties of materials, typically metals. It can enhance hardness, strength, toughness, and ductility, among other properties.
17. What is knurling in a workshop?
Answer:
Explanation:
Knurling is a machining process that creates a regular cross-hatched pattern on the surface of a metal part. It is commonly used to provide a better grip on tools and dials.
18. What is electroplating commonly used for in a workshop?
Answer:
Explanation:
Electroplating is a process used to coat the surface of one metal with a thin layer of another metal. This can be for aesthetic purposes, corrosion resistance, or to improve electrical conductivity.
19. What is a vernier caliper used for in a workshop?
Answer:
Explanation:
A vernier caliper is a precision measuring tool used to measure internal and external dimensions, as well as depths, with high accuracy.
20. What is the main advantage of using a CNC machine over a conventional machine?
Answer:
Explanation:
CNC machines offer higher accuracy and repeatability compared to conventional machines. They are computer-controlled, allowing for precise and consistent manufacturing of complex parts.
21. What is the purpose of a broach in a workshop?
Answer:
Explanation:
A broach is a tool used in workshops to remove material and create a specific profile or hole, often with a unique or complex shape. It's particularly useful for machining keyways, splines, and other profiles.
22. What is the significance of a surface roughness gauge in a workshop?
Answer:
Explanation:
A surface roughness gauge is used to quantify the texture or roughness of a surface. It provides precise measurements of surface irregularities, which is important for quality control in manufacturing.
23. What is the main purpose of a hacksaw in a workshop?
Answer:
Explanation:
A hacksaw is a common tool in workshops used for cutting through metal or plastic. It consists of a frame holding a thin serrated blade and is operated by hand.
24. What process involves heating a metal until it's pliable and then hammering it into shape?
Answer:
Explanation:
Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The metal is heated until it becomes pliable and is then formed into a desired shape by hammering or pressing.
25. What is the function of a scriber in metalworking?
Answer:
Explanation:
A scriber is a hand tool used in metalworking to mark lines on metal surfaces. It is used for layout and marking purposes before cutting or machining the metal.
