Definition and Overview
Waterjet cutting, also known as hydrodynamic machining, is a non-contact cutting process that utilizes a high-pressure stream of water, often mixed with abrasive particles, to cut through materials. This method is highly versatile, capable of cutting diverse materials such as metals, plastics, glass, and composites without generating heat, making it ideal for heat-sensitive substances. The process involves pumping water to extremely high pressures, typically between 30,000 to 90,000 psi, and focusing it through a nozzle to create a precise, erosive cutting tool. Its precision, eco-friendliness, and ability to handle complex shapes have made it a preferred choice across industries like aerospace, automotive, and artistic fabrication.
Historical Development and Evolution
The concept of waterjet cutting originated in the 1950s, initially used in the forestry industry for cutting soft materials like wood. Early systems operated at relatively low pressures and were limited in their capabilities. The 1970s and 1980s saw significant advancements, with the introduction of high-pressure pumps and abrasive waterjet cutting, enabling the process to cut harder materials like metals and ceramics. Modern waterjet systems now operate at pressures exceeding 90,000 psi, offering precise and efficient cutting solutions.

Working Principle of Waterjet Cutting
Waterjet cutting uses a high-pressure water stream, often mixed with abrasives, to erode and cut materials. The process begins with a pump generating ultra-high-pressure water, which is then forced through a small nozzle, creating a focused cutting stream capable of slicing through various materials without generating heat.
Basic Principles and Mechanisms
Waterjet cutting operates by propelling water at ultra-high pressures (up to 94,000 psi) through a narrow nozzle, creating a focused stream. This stream erodes material through particle impact and cavitation. For tougher materials, abrasives like garnet are added, enhancing cutting efficiency. The process relies on the kinetic energy of the water and abrasive particles, which progressively remove material without generating heat. This cold cutting mechanism preserves material properties and prevents thermal damage, making it ideal for heat-sensitive materials. The precision and versatility of waterjet cutting stem from its ability to adjust pressure, flow rate, and abrasive usage.
Key Components of a Waterjet Cutting System
