Hot Water Knife Cutting: Benefits, Optimization, And Applications

A hot water knife is a cutting tool that uses a high-pressure jet of hot water to cut through materials. It operates on the principle of thermal cutting, where the high-temperature water melts or vaporizes the material at the cutting point. Compared to abrasive waterjet cutting and laser cutting, hot water cutting offers advantages such as lower operating costs, reduced environmental impact, and increased safety. The cutting mechanism involves heating the material and using the water jet to remove the molten or vaporized material. Factors affecting cutting efficiency include water pressure, temperature, and flow rate. Optimization of cutting speed involves consideration of material properties and water parameters. Safety considerations are essential, including proper handling and operation to prevent injuries and equipment damage. Industrial applications include shape cutting, material separation, and metal cleaning.
