1. CAD stands for which of the following?
A. Computer-Aided Drawing
B. Computer-Assisted Design
C. Computer-Aided Design
D. Computational Applied Design
Computer-Aided Design (CAD) refers to the use of computer systems to
assist in the creation, modification, analysis, or optimization of a design.
2. CAM primarily refers to the use of software to:
A. Analyze financial data
B. Control machine tools
C. Document engineering changes
D. Generate marketing materials
Computer-Aided Manufacturing (CAM) software is used to control machine
tools and automate manufacturing processes.
3. In CAD modeling, a “parametric constraint” allows the designer to:
A. Change the part color
B. Encrypt the model file
C. Restrict software updates
D. Define relationships between dimensions
,Parametric constraints establish relationships among dimensions that
automatically update features when changes are made.
4. Which of the following is a common file format used for 3D CAD
models?
A. .DOCX
B. .MP3
C. .STEP
D. .TXT
The STEP (.STEP) format is widely used for exchanging 3D CAD data
between different CAD systems.
5. G-code in CAM programming is used to:
A. Edit images
B. Compile data sheets
C. Instruct machine movement
D. Generate architectural plans
G-code provides commands that direct machine tools on how to move and
operate during manufacturing.
6. A “toolpath” in CAM refers to:
A. A marketing strategy
B. A wiring schematic
C. Path followed by the cutting tool
D. A project budget plan
Toolpath describes the trajectory the cutting tool follows to shape the
workpiece.
7. In CAD assemblies, “mates” are used to:
A. Encrypt the model
B. Share files over a network
C. Define relationships between components
D. Assign material properties
, Mates constrain how parts fit and move relative to one another in an
assembly.
8. The term “rapid prototyping” is associated with:
A. Slow production cycles
B. Additive manufacturing techniques
C. Manual drafting
D. Financial auditing
Rapid prototyping typically uses additive processes like 3D printing to
quickly create models.
9. In machining operations, the feed rate refers to:
A. File download speed
B. Rate at which the tool advances into material
C. Electrical current to a machine
D. Software update frequency
Feed rate is the speed at which the cutting tool advances through material.
10. “CAD rendering” is the process of:
A. Writing financial reports
B. Laser cutting
C. Measuring temperature
D. Creating a photorealistic image of a model
Rendering produces a realistic visual representation of a CAD model.
11. A “solid model” in CAD is:
A. An audio file
B. A 2D sketch
C. A spreadsheet
D. A complete 3D representation with volume
Solid models represent the complete geometry and volume of an object,
not just surfaces.
