1. What is the primary advantage of laser cutting compared to
mechanical cutting?
A. Lower equipment cost
B. High precision with minimal material distortion
C. Slower cutting speed
D. Increased tool wear
Laser cutting provides high accuracy and minimal heat-affected
zones compared to mechanical methods.
2. Which laser type is most commonly used for cutting metals in
industrial applications?
A. CO₂ laser
B. Diode laser
C. Fiber laser
D. Excimer laser
Fiber lasers offer high efficiency, excellent beam quality, and are
well-suited for metal cutting.
,3. The heat-affected zone (HAZ) refers to:
A. Area directly vaporized by the laser
B. Material region altered by heat but not melted
C. Cooling zone after cutting
D. Optical distortion in the beam
HAZ is the region where material properties change due to heat
exposure.
4. Which gas is most commonly used as an assist gas for cutting mild
steel?
A. Nitrogen
B. Argon
C. Oxygen
D. Helium
Oxygen enhances the cutting process through an exothermic
reaction with steel.
5. What is the main function of assist gas in laser cutting?
A. Cool the laser source
B. Increase beam wavelength
C. Remove molten material and improve cut quality
D. Reduce electrical consumption
Assist gas clears molten material and stabilizes the cutting
process.
6. A shorter laser wavelength generally results in:
A. Lower absorption
B. Better absorption by metals
C. Wider kerf
D. Increased beam divergence
Shorter wavelengths are absorbed more efficiently by metallic
surfaces.
, 7. Kerf width refers to:
A. Laser beam diameter
B. Material thickness
C. Width of material removed by cutting
D. Heat-affected zone size
Kerf is the cut width created by the laser beam.
8. What parameter most directly affects cutting speed?
A. Lens material
B. Laser power
C. Machine frame size
D. Cooling system
Higher laser power allows faster cutting through material.
9. Which safety classification do most industrial laser cutting
systems fall under?
A. Class 1
B. Class 2
C. Class 3R
D. Class 4
Industrial laser cutters are typically Class 4 due to high power
levels.
10. Why is proper focus position critical in laser cutting?
A. Reduces electrical consumption
B. Ensures optimal energy density at the cut point
C. Increases assist gas pressure
D. Prevents machine vibration
Correct focus maximizes cutting efficiency and quality.
11. What happens if the laser focus is set too high above the
material surface?
A. Narrower kerf
