CNC Cutting Machine Practice Test 2025 – Complete Exam Preparation

CNC plasma cutters are specifically designed for cutting electrically conductive materials, which includes a wide range of metals such as steel, aluminum, copper, and brass. The process utilizes a high-velocity jet of ionized gas (plasma) which can easily melt and blow away the material as it moves through, making it highly effective for metalwork.

While options that suggest restricting the cutting capabilities to wood, soft plastics, or ceramics mischaracterize the primary function of plasma cutting, the versatility of CNC plasma cutters allows them to efficiently process various types of metals. This functionality is what makes plasma cutting a popular choice in industries requiring precise and clean cuts in metallic materials.
