“…Water jet mass flow (m w ) is defined by this equation where mw-water jet mass flow rate, -water density, qwwater jet flow rate. This is an essential factor in water jet power, as it represents the kinetic energy of the abrasive water jet stream [6]. (6) Water jet flow rate is defined by this equation where qwwater jet flow rate, coefficient of discharge (c d =0.6-0.8), orifice diameter (d o ), water pressure, and water density.…”

Water jet cutting has been an extremely helpful tool that creates flawless parts with tolerances up to 0.1 mm. During the cutting process, it is important to note that each step must be optimized to create the best finish or maintain the correct tolerance zone. These steps are composed of abrasive mass flow rate, traverse speed, and standoff distance. In order for these optimization techniques to be followed a strict set of rules must be followed to ensure consistent progression. Programs such as MATLAB can be utilized to reduce human error in the calculations. MATLAB files can then be saved to use with other materials and thickness combinations.
