What is brazing primarily used for in workshop practice?
A Cutting metal
B Measuring parts
C Joining metal parts
D Shaping metal
Brazing is a process where metal parts are joined by melting and flowing a filler metal into the joint. It is used to create strong bonds at lower temperatures compared to welding, ideal for delicate components or dissimilar metals.
What does a micrometer primarily measure?
A Thickness
B Diameter
C Width
D Length
A micrometer is used for measuring the thickness or outer diameter of small objects with high precision. It uses a calibrated screw to provide accurate readings, typically for measuring parts like shafts, rods, and other cylindrical items.
What is the purpose of inspection in workshop practice?
A To shape parts
B To improve quality
C To join parts
D To clean tools
Inspection is used to assess the quality of parts, ensuring they meet required specifications and standards. It involves checking dimensions, surface finish, and other parameters, preventing defects and ensuring that products are fit for their intended purpose.
What is the main function of a lathe in a workshop?
A Drilling holes
B Cutting metal
C Turning material
D Polishing surfaces
A lathe is primarily used for turning, where a workpiece is rotated while a cutting tool shapes it. This operation is crucial for producing cylindrical parts like shafts and pipes, allowing for high precision and symmetry.
What type of inspection tool is typically used to measure small parts?
A Vernier caliper
B Ruler
C Square
D Micrometer
A micrometer is designed for highly accurate measurements of small parts, especially for measuring the thickness or diameter of components. It is ideal for parts requiring high precision, where other tools like Vernier calipers might not provide the accuracy needed.
What is the function of a production tool in workshop practice?
A Making repeated parts
B Measuring dimensions
C Shaping materials
D Joining parts
Production tools are designed to efficiently produce parts in high quantities, ensuring consistency and precision across many units. Examples include jigs, fixtures, and dies, which help in mass production and ensure that parts are made quickly and accurately.
Which method is commonly used for inspecting surface quality?
A Micrometer measurement
B Tapping
C Visual inspection
D Grinding
Visual inspection is commonly used to check the surface quality of parts. Inspectors look for defects like cracks, scratches, and surface irregularities. It is often the first step in quality control before more detailed measurements are taken.
Which of the following is a key characteristic of brazing?
A Requires high temperature
B Melts the base metals
C Involves welding
D Uses filler metal
Brazing involves using a filler metal to join metal parts at a temperature above 450°C, without melting the base metals. The filler metal is melted and flows into the joint, creating a strong bond once it solidifies.
What is the purpose of a depth gauge?
A To measure depth of holes
B To measure height
C To measure internal dimensions
D To measure surface roughness
A depth gauge is used to measure the depth of holes, slots, or recesses in a workpiece. It helps ensure that the workpiece is machined to the correct depth, which is crucial for parts that fit together precisely.
What type of production tool is used for cutting metal parts in a specific shape?
A Drill
B Die
C Hammer
D Saw
A die is a tool used to cut or shape metal parts by applying high force. It is commonly used in processes like stamping, molding, and punching to produce parts with specific, consistent shapes in mass production settings.
What is the function of a file in workshop practice?
A Cutting material
B Polishing surfaces
C Smoothing and shaping
D Measuring dimensions
A file is used for smoothing rough edges and surfaces of materials. It is particularly useful in metalworking and woodworking to refine the shape of parts, remove burrs, and provide a smooth finish for further operations.
What is a key characteristic of a welding inspection?
A Checking the surface color
B Measuring the weight of parts
C Cutting the materials
D Checking the strength of welds
Welding inspection primarily focuses on evaluating the strength and integrity of welds. This involves visual inspection, non destructive testing, and sometimes destructive testing to ensure that the welds can withstand the required loads and conditions.
Which production tool is commonly used for repetitive cutting in manufacturing?
A CNC machine
B Milling machine
C Saw
D Lathe
A CNC (Computer Numerical Control) machine is used for repetitive and precise cutting in manufacturing. It is programmed to perform various operations like milling, drilling, and turning, offering high efficiency and repeatability in production processes.
What is the purpose of an inspection gauge?
A To heat materials
B To join materials
C To measure part dimensions
D To polish parts
An inspection gauge is used to measure the dimensions of a part during the inspection process. It helps ensure that the part meets the specified tolerances and quality standards, aiding in quality control in manufacturing.
What type of maintenance focuses on identifying potential failures before they occur?
A Corrective maintenance
B Predictive maintenance
C Preventive maintenance
D Reactive maintenance
Predictive maintenance uses data and monitoring tools to predict when equipment is likely to fail. It allows for maintenance to be performed just before a failure occurs, helping to avoid downtime and reduce maintenance costs.
