fitting shop

1.What is the purpose of a fitting shop in manufacturing processes?

 Answer: The purpose of a fitting shop is to perform various operations such as cutting, shaping, assembling, and finishing of components to achieve accurate dimensions and fit for final assembly.

2.List some common hand tools used in a fitting shop.

Answer: Some common hand tools used in a fitting shop include wrenches, screwdrivers, pliers, hammers, chisels, files, hacksaws, measuring tools (such as calipers and micrometers), and spanners.

3.Explain the difference between a tap and a die in the context of fitting shop operations.

Answer: A tap is a cutting tool used to create internal threads in a pre-drilled hole, while a die is used to create external threads on cylindrical objects such as bolts or rods. Taps are used for threading holes, whereas dies are used for threading bolts or rods.

4.What safety precautions should be taken when working in a fitting shop?

Answer: Some safety precautions in a fitting shop include wearing appropriate personal protective equipment (PPE) such as safety glasses, gloves, and hearing protection, ensuring proper ventilation, keeping the work area clean and organized, using tools and equipment correctly, and following proper lockout/tagout procedures when working on machinery.

5.Describe the procedure for threading a pipe using a pipe threader in a fitting shop. Answer: The procedure for threading a pipe using a pipe threader typically involves securing the pipe in a pipe vise, applying cutting oil to the pipe and the threader, aligning the threader with the pipe, and rotating the threader to cut the threads into the pipe. The pipe is periodically reversed to break and remove the chips during the threading process.

6.What is the purpose of a reamer, and when is it typically used in a fitting shop?

Answer: A reamer is a cutting tool used to smooth and enlarge holes to achieve precise dimensions and a smooth finish. It is typically used after drilling a hole to remove any rough edges or imperfections and ensure accurate sizing for fitting components or fasteners.

7.How do you measure the size of a bolt or screw in a fitting shop?

Answer: The size of a bolt or screw is typically measured using a caliper or a thread pitch gauge. The caliper is used to measure the major diameter (outer diameter) of the bolt or screw, while the thread pitch gauge is used to determine the pitch or the number of threads per unit of length.

8.Discuss the importance of proper lubrication in fitting shop operations. Answer: Proper lubrication is important in fitting shop operations as it reduces friction, heat, and wear between moving parts. It helps in smooth operation, extends the lifespan of tools and equipment, improves accuracy in machining operations, and prevents damage to components.

9.What are the different types of files used in a fitting shop, and what are their specific applications?

Answer: Different types of files used in a fitting shop include flat files (for general filing and flat surfaces), round files (for enlarging holes or shaping curved surfaces), half-round files (for flat and curved surfaces), and triangular files (for filing corners or angles). Each type of file has specific applications based on the shape of the workpiece and the desired finish.

10.Describe the process of deburring and its significance in a fitting shop.

 Answer: Deburring is the process of removing burrs or sharp edges from machined or cut metal surfaces. It is typically done using files, grinding wheels, or specialized deburring tools. Deburring is significant in a fitting shop as it improves the safety of components, prevents injuries, enhances the fit and finish of assembled parts, and ensures proper functionality.
