Question 1 Report
A company uses laser cutting to produce decorative steel panels for garden fences. The panels are designed using CAD software and the designs are sent directly to the laser cutter.
(a) Give two advantages of using laser cutting to produce the decorative panels compared to cutting them by hand with a saw. [2]
(b) Name one other computer-controlled cutting or shaping process, apart from laser cutting, that could be used to produce these panels. [1]
Answer Details
(a) Two advantages of laser cutting for decorative steel panels compared to hand cutting with a saw:
- Laser cutting produces very precise, intricate shapes with clean, smooth edges that would be extremely difficult or impossible to achieve by hand with a saw, especially for decorative patterns with tight curves and fine detail. [1]
- Every panel is cut identically with consistent accuracy and repeatability, ensuring uniform appearance across a full production run. [1]
Other valid advantages include faster cutting speed for complex patterns, no physical tool contact with the material (eliminating tool wear and clamping distortion), and narrow kerf width that minimises material waste.
(b) One other computer-controlled cutting or shaping process:
CNC plasma cutting [1] - plasma cutting uses a high-temperature ionised gas jet to cut through conductive metals and is often CNC-controlled for automated production. CNC water jet cutting and CNC milling/routing are also valid alternatives.
