Water jet machining is also known as water jet cutting. Water jet machining is frequently employed in various industrial applications. Softer materials like plastic, rubber, and wood can be sliced with WJM. However, an abrasive material is combined with water to cut tougher objects, such as metals or granite. Abrasive water jet machining (AWJM) is the machining technique in which an abrasive material is employed in water and applied by a very high-pressure jet of water to the workpiece to achieve the desired shape and size, or to remove materials off the surface of a workpiece.

Working Theory of Water Jet Machining
The foundation of water jet machining (WJM) is the idea of water erosion. Material removal occurs when a fast-moving jet of water impacts the surface. Softer materials are machined using a pure water jet. However, some abrasive particles mixed with water for machining are used to cut tougher materials, and this process is known as AWJM.
Abrasive Substances for Water Jet Machining
The abrasive particles’ purpose is to improve the water jet's capacity for cutting. Garnet and aluminum oxide are the two abrasive materials used in AWJM the most frequently. Glass beads and sand (Si02) are additional abrasives used regularly.
Principal Components of Water Jet Machines
The main components of water jet machines include:
During the machining process, it circulates the water from the storage tank. Then, water is delivered to the intensifier by the pump at a low pressure of approximately 5 bars. Additionally, a booster raises the water's starting pressure to 11 bars before transferring it to the intensifier.
It is used to raise the water's pressure to extremely high pressure. It gets water from the pump at a pressure of 4 bar and raises it to between 3000 and 4000 bar.
The high-pressure water is temporarily stored there. When a significant amount of pressure energy is needed, it provides that fluid. It gets rid of the machining process's pressure fluctuation circumstances.
A Mixing Tube or Chamber
The blending of abrasive particles and water takes place in a vacuum chamber.
This device controls the water jet's pressure and direction.
Flow Regulator or Valve
The flow regulator assists in controlling the water's flow.
It is a tool used in water jet machining to transform the pressure energy of water into kinetic energy. The nozzle transforms the water jet's pressure into a high-velocity beam. The tip is constructed of diamond or ruby to prevent nozzle erosion.
Drain and Catcher System
With the aid of the drain and catcher system, the debris and machined particles from the water are separated after the machining.
Water Jet Cuts Types
Water jet cuts made in one dimension are stationary cuts created while the workpiece passes through the water jet cutting device. They are used for trimming and are the most basic type of cut. While the debris and water are captured on the other side, the operator feeds the workpiece into the cutting tool. A slitter, which divides pieces into predetermined widths, is a version of the one-dimensional cutter. Water alone or mixed with an abrasive can be used as one-dimensional cutters.
XY in Two Dimensions
PC or CNC programming is required for two-dimensional cutting. They have a closed-loop feedback servo motor to regulate cutting speed and placement. Catcher tanks support the workpiece with slats and are filled with water. An XY two-dimensional cutting machine's Z section regulates the height of the cutting tool to accommodate variations in the workpiece's thickness. Cutting in two dimensions is best for quickly and accurately removing material from various items.
XYZ in Three Dimensions
The X-axis, which goes from left to right, the Y-axis, which moves from front to back, and the Z-axis, which moves up and down, are all used in three-dimensional cutting. In the three-axis process, the cutting tool moves along the three planes while the workpiece stays still. It is a method for creating mechanical parts.
XYZA in Four Dimensions
When cutting in four dimensions, the workpiece is treated along the three XYZ axes and in a fourth dimension by rotating around the X axis. The workpiece can be sliced along the B axis thanks to the A axis cutting. It is a great technique for creating holes or other apertures in the sides of a workpiece. With the A axis included, it is possible to automatically flip the workpiece so that the waterjet may remove material from both sides.
Advantages of Water Jet Machining
- It can cut materials without affecting their original structure. And the reason why this occurs is that there is no heat-affected zone (HAZ).
- It can cut materials with elaborate and complex patterns.
- During this machining process, the workspace is kept pristine and free of dust.
- Due to the limited need for moving parts, it requires little maintenance.
- Due to low heat generation, the workpiece suffers very little thermal damage.
- Both softer materials like rubber, plastic, or wood and tougher materials like granite can be cut with it; WJM for softer materials and AWJM for tougher materials.
- It is eco-friendly because it doesn't produce any hazardous waste or pollutants.
- The greater machining precision is present. It is simple to attain tolerances of an order of 0.005 inches.
Applications of Water Jet Cutting
Water jet machining is employed in various industries, including mining, automotive, and aerospace, for cutting, shaping, and reaming operations. Rubber, textiles, plastics, foam, leather, composites, tile, stone, glass, food, metals, paper, and many more materials are commonly manufactured using water jet machining (WJM or AWJM).
The primary applications for WJM are cutting soft and simple-to-machine materials, including thin sheets and foils, wood, non-ferrous metallic alloys, textiles, honeycomb, plastics, polymers, leathers, frozen food, etc. Hard and challenging-to-machine materials are often machined with AWJM. For example, it is used to cut thick plates made of steel, aluminum, and other industrial materials and reinforced polymers, multilayer composites, metal matrix, and ceramic matrix composites. The high-pressure water jet is also utilized in cleaning, surgery, peening to eliminate residual stress, and other processes aside from machining.
