Cutting is a manufacturing method used to separate or shape materials by removing unwanted sections. Flame cutting utilizes a high-temperature flame to melt and blow away the material. Plasma cutting uses a jet of ionized gas to create an electrical arc, melting and removing the material. Laser cutting employs a concentrated laser beam to vaporize or melt the material precisely. Water cutting uses a high-pressure jet of water mixed with an abrasive substance to erode and cut through the material. Each method has its advantages and is chosen based on the material type, thickness, precision requirements, and cost considerations.
