Cutting and shaping are processes used in manufacturing and other industries to create various shapes, sizes, and designs in materials such as metal, wood, plastic, and others. The common classes of cutting and shaping include:
1. Machining - This involves the use of machine tools such as lathes, milling machines, grinders, and drilling machines to remove material and shape the workpiece.
2. Shearing - This involves the use of a tool to cut a material along a straight line, such as in cutting sheet metal or paper.
3. Sawing - This involves the use of saw blades to cut materials such as wood, metal, and plastic into desired shapes.
4. Grinding - This involves the use of abrasive wheels or belts to remove material and shape the workpiece.
5. Laser cutting - This involves the use of a high-powered laser beam to cut and shape materials such as metal, wood, and plastic.
6. Waterjet cutting - This involves the use of a high-pressure stream of water mixed with abrasive particles to cut and shape materials.
7. Plasma cutting - This involves the use of a high-temperature plasma arc to cut and shape materials such as metal and steel.
8. Electrical discharge machining (EDM) - This involves the use of electrical sparks to erode and shape the workpiece.
These are some of the common classes of cutting and shaping used in modern manufacturing and production processes.
