CNC Cutting Machine Practice Test 2025 – Complete Exam Preparation

The operation of a CNC flame cutter is based on the oxy-fuel process, which involves the use of a mixture of oxygen and fuel gas, typically acetylene, to generate a flame that can reach extremely high temperatures. This intense heat melts the metal, and as the flame is directed onto the material, the molten metal is blown away by the force of the oxygen. This method is particularly effective for cutting through ferrous metals and is often used in heavy industries due to its ability to cut thick materials.

The oxy-fuel process is well-suited for CNC applications because it allows for precise control over cutting speed and torch angle, enabling operators to achieve desired shapes and sizes with accuracy. This is essential in manufacturing environments where consistency and repeatability are crucial for product quality.

Other options involve different cutting technologies but do not pertain to the operation of a CNC flame cutter. For instance, laser technology is effective for precise cuts but operates on a different principle involving focused light. Water jet technology uses high-pressure water streams for cutting and is recognized for its ability to work with a variety of materials without tarring or melting them. Plasma cutting, while also a viable method for metal cutting, utilizes ionized gas at high temperatures rather than the combustion process found in
