What is the primary advantage of using CNC machines in manufacturing?

  1. They offer higher precision and accuracy compared to manual machining

  2. They enable faster production rates and increased productivity

  3. They reduce the need for skilled labor and operator intervention

  4. All of the above

Show answer
Correct Option: D
Explanation:

CNC machines provide higher precision, faster production rates, and reduced reliance on skilled labor, leading to improved efficiency and productivity.

Which of the following is NOT a common application of CAD/CAM systems in the manufacturing industry?

  1. Automotive design and manufacturing

  2. Aerospace engineering and manufacturing

  3. Medical device design and manufacturing

  4. Construction and architecture

Show answer
Correct Option: D
Explanation:

While CAD/CAM systems are widely used in various industries, they are not commonly used in construction and architecture. These fields typically use specialized software for design and modeling.

What is the term used to describe the process of converting a digital design into a physical product using CAD/CAM systems?

  1. Computer-Aided Manufacturing (CAM)

  2. Computer-Integrated Manufacturing (CIM)

  3. Rapid Prototyping

  4. Additive Manufacturing

Show answer
Correct Option: A
Explanation:

Computer-Aided Manufacturing (CAM) refers to the process of using CAD software to generate instructions and toolpaths for CNC machines, which then produce the physical product.

Which of the following is NOT a common type of rapid prototyping technology used in CAD/CAM systems?

  1. Stereolithography (SLA)

  2. Selective Laser Sintering (SLS)

  3. Fused Deposition Modeling (FDM)

  4. Injection Molding

Show answer
Correct Option: D
Explanation:

Injection Molding is not a rapid prototyping technology. It is a traditional manufacturing process used for mass production of plastic parts.

What is the primary benefit of using rapid prototyping technologies in the product development process?

  1. They allow for quick and cost-effective testing of design concepts

  2. They reduce the need for expensive tooling and molds

  3. They enable faster iteration and design refinement

  4. All of the above

Show answer
Correct Option: D
Explanation:

Rapid prototyping technologies offer several benefits, including quick and cost-effective testing, reduced tooling costs, and faster design iteration.
