Fitter Skills Assessment

What is the primary function of a fitter?

• To perform routine maintenance on existing machines.

• The primary function of a fitter is to assemble and install machinery and equipment.

• To manage a team of engineers and technicians.

• To design new machinery and equipment.

Explain the difference between a bolt and a screw.

• A bolt is always longer than a screw.

• A bolt requires a nut, while a screw can be used alone.

• A screw is used for electrical connections, while a bolt is not.

• Bolts are made of plastic, whereas screws are made of metal.

What tools are commonly used by fitters?

• Sanders

• Drills

• Wrenches, pliers, screwdrivers, hammers, measuring tapes, levels

• Saws

Describe the process of measuring a workpiece accurately.

• Take a single measurement and assume it's correct

• Use the appropriate measuring tool, ensure cleanliness, zero the tool, position it correctly, take multiple measurements, and record the results.

• Use a ruler without checking for accuracy

• Ignore the cleanliness of the workpiece before measuring

What safety precautions should be taken while working with machinery?

• Work alone without supervision

• Use loose clothing

• Wear PPE, ensure training, conduct maintenance checks, keep work area clean, follow lockout/tagout procedures.

• Ignore machine warnings

How do you interpret technical drawings?

• Use only the notes without considering symbols or views

• Read technical drawings by guessing the dimensions

• Interpret technical drawings by analyzing the title block, scale, symbols, views, and notes.

• Ignore the title block and focus only on colors

What is the significance of tolerances in fitting work?

• Tolerances only affect aesthetic aspects of components.

• Tolerances are irrelevant in mechanical design.

• Tolerances are significant as they ensure proper fit, function, and performance of components in mechanical assemblies.

• Tolerances are only necessary for electrical fittings.

Explain the term 'machining' in the context of fitting.

• Machining is the process of removing material to achieve precise dimensions and fits in mechanical components.

• Machining refers to the use of heat treatment to strengthen materials.

• Machining is the process of assembling components without any material removal.

• Machining is the process of applying coatings to enhance surface properties.

What materials are typically used in fitting applications?

• Wood (pine, oak)

• Metals (stainless steel, brass, copper), plastics (PVC, PEX)

• Glass (tempered, laminated)

• Rubber (natural, synthetic)

How do you maintain tools and equipment used in fitting?

• Only use tools when necessary.

• Regularly clean, inspect, lubricate, and store tools properly.

• Ignore any signs of wear or damage.

• Store tools in a wet environment.
