Fitting and Assembling Techniques

What is the purpose of mechanical assembly techniques?

• To enhance the aesthetic appeal of components.

• To reduce the weight of the assembled product.

• To create a temporary connection between parts.

• To join components together in a structured manner for functionality and stability.

Name three common mechanical assembly techniques.

• Fastening, welding, adhesive bonding

• Soldering, riveting, casting

• 3D printing, machining, forging

• Molding, assembling, cutting

What is the difference between permanent and temporary fastening methods?

• Permanent fastening methods can be easily removed without tools.

• Permanent fastening methods are always more expensive than temporary methods.

• Permanent fastening methods create a lasting bond, while temporary methods allow for disassembly.

• Temporary methods are used for structural integrity, while permanent methods are not.

List two types of fasteners used in mechanical assembly.

• Nails

• Clips

• Bolts, Screws

• Rivets

What materials are commonly used for fasteners?

• Rubber

• Glass

• Steel, stainless steel, aluminum, brass, plastic

• Wood

Explain the role of torque in fastening methods.

• Torque is essential in fastening methods as it determines the tightness and integrity of the joint.

• Torque is irrelevant in fastening methods.

• Torque only affects the appearance of the joint.

• Torque is used solely for loosening fasteners.

What is the importance of alignment in mechanical assembly?

• Alignment is only necessary for aesthetic purposes.

• Alignment is primarily for reducing production costs.

• Alignment has no impact on the performance of mechanical assemblies.

• Alignment is crucial for optimal performance, longevity, and ease of maintenance in mechanical assemblies.

Describe a method for aligning components during assembly.

• Align components by eye without any tools.

• Use glue to hold components together temporarily.

• Use jigs and fixtures to hold components in place for precise alignment during assembly.

• Stack components randomly and hope for the best.

What tools are typically used for adjustment procedures?

• Pliers

• Saws

• Hammers

• Wrenches, screwdrivers, calibration gauges, measuring instruments

How can misalignment affect the performance of an assembly?

• Misalignment negatively impacts assembly performance by causing wear, increased friction, and potential component failure.

• Misalignment only affects the aesthetic appearance of the assembly.

• Misalignment has no effect on assembly performance.

• Misalignment improves assembly performance by reducing friction.
