Cutting materials refers to the various substances used in the process of cutting or shaping other materials. Common cutting materials include metals, plastics, and ceramics, which can be shaped using tools like knives, saws, or lasers. The choice of cutting material depends on the specific application and the properties required, such as hardness, durability, and resistance to wear. In industrial settings, cutting materials are often categorized based on their hardness and ability to maintain a sharp edge. For example, high-speed steel and carbide are popular choices for cutting tools due to their strength and heat resistance. Proper selection of cutting materials is essential for achieving efficient and precise results in manufacturing and construction.
