Metal cutting is a machining process used to remove unwanted material from a metal workpiece to achieve the required shape, size, and surface finish. Common metal cutting operations include turning, drilling, milling, grinding, and sawing.
Different machines such as lathes, drilling machines, milling machines, and CNC machines are used in metal cutting. The process involves selecting the correct tool, setting the machine, securing the workpiece, and performing the cutting operation safely.
Metal cutting provides high accuracy, good surface finish, and efficient production, but it may cause tool wear and requires proper maintenance. Safety precautions such as wearing PPE and using machine guards are important during operations.
