1. What is the primary purpose of CAD software?
A. Operate CNC machines directly
B. Create and modify part designs
C. Inspect finished parts
D. Measure tool wear
Answer: B. Create and modify part designs
Rationale: CAD (Computer-Aided Design) software is used to
create, edit, and document product designs.
2. What is the primary purpose of CAM software?
A. Create engineering drawings
B. Manage inventory
C. Generate CNC toolpaths and machining instructions
D. Calibrate measuring equipment
Answer: C. Generate CNC toolpaths and machining
instructions
,Rationale: CAM (Computer-Aided Manufacturing) converts
CAD models into machine-readable toolpaths.
3. Which file format is commonly used to exchange 3D CAD
models between different systems?
A. TXT
B. STEP
C. DOCX
D. JPG
Answer: B. STEP
Rationale: STEP files provide a standardized method for
exchanging 3D model data.
4. What does CNC stand for?
A. Computer Numerical Control
B. Computer Network Control
C. Central Numerical Calibration
D. Coordinate Network Control
Answer: A. Computer Numerical Control
Rationale: CNC refers to automated machine control through
programmed instructions.
5. Before creating CAM toolpaths, what should typically be
completed first?
,A. Machine setup sheet
B. Tool presetting
C. CAD model creation
D. Part inspection
Answer: C. CAD model creation
Rationale: CAM software requires a part model or geometry
before generating toolpaths.
6. Which coordinate system is typically attached to the
workpiece?
A. Machine Coordinate System
B. Work Coordinate System
C. Servo Coordinate System
D. Encoder Coordinate System
Answer: B. Work Coordinate System
Rationale: The work coordinate system establishes the part
zero location.
7. What is a toolpath?
A. A machine maintenance schedule
B. The route a cutting tool follows during machining
C. A fixture design
D. A quality inspection report
Answer: B. The route a cutting tool follows during
machining
, Rationale: Toolpaths define cutter movement for material
removal.
8. Which machining operation is typically used to remove
large amounts of material quickly?
A. Finishing
B. Engraving
C. Roughing
D. Deburring
Answer: C. Roughing
Rationale: Roughing operations prioritize material removal
rate over surface finish.
9. Which operation is performed after roughing to achieve
final dimensions?
A. Facing
B. Finishing
C. Drilling
D. Spotting
Answer: B. Finishing
Rationale: Finishing operations produce final size, accuracy,
and surface quality.
10. What is the purpose of simulation in CAM software?
