Automotive: Plasma cutting is used for cutting sheet metal and structural components in automotive industries, especially for parts requiring fast turnaround and moderate precision.

4. Waterjet Cutting

Description: Waterjet cutting involves the use of a high-pressure stream of water, often mixed with an abrasive material like garnet, to cut through materials. It can cut a variety of materials including metals, glass, stone, ceramics, and composites.

Applications:

Stone and Tile Cutting: Waterjet cutting is often used in the stone, marble, and tile industries to create intricate shapes and designs. The cold-cutting nature of waterjet cutting prevents the material from cracking or distorting.
Composites and Laminates: Waterjet cutting is ideal for cutting composite materials used in industries like automotive, and construction, as it does not affect the integrity of layered structures.
Metal Cutting: While less common for cutting thick metals than plasma or laser, waterjet cutting is used for precision cuts in metals, especially when heat-affected zones are a concern.

5. Oxy-Fuel Cutting (Oxy-Acetylene Cutting)

Description: Oxy-fuel cutting uses a combination of oxygen and a fuel gas (typically acetylene) to heat the material to its ignition point and then blow the molten material away. It is mostly used for cutting ferrous metals (iron and steel).

Applications:

Heavy Plate Cutting: This method is commonly used for cutting thicker steel plates, especially in the construction and shipbuilding industries.
Scrap Metal Cutting: Oxy-fuel cutting is often employed in the recycling industry to cut scrap metal into smaller, manageable pieces for further processing.
Pipeline Cutting: Oxy-fuel is often used for cutting large-diameter pipes in the oil, gas, and chemical industries, especially for field repairs.

6. Bandsaw Cutting

Description: Bandsaw cutting uses a continuous band of teeth mounted on a set of wheels to cut through materials. This method is often used for cutting wood, metal, and other materials in a straight line or around curves.

Applications:

Woodworking: In woodworking, bandsaws are used for cutting large sheets of wood or making intricate curves for furniture or cabinetry.
Metal Cutting: Bandsaws are used to cut metal bars, pipes, and other structural materials, especially for applications requiring straight cuts and medium precision.
Pipe and Tube Cutting: Bandsaws are also used in industries like plumbing, oil, and gas for cutting pipes and tubes into specific lengths.

7. Wire EDM (Electrical Discharge Machining)
