Edge quality for water jet cut parts

Edge quality for water jet cut parts is defined with the quality numbers Q1 through Q5.


Lower numbers indicate rougher edge finish; higher numbers are smoother. For thin materials, the difference in cutting speed for Q1 could be as much as 3 times faster than the speed for Q5.

For thicker materials, Q1 could be 6 times faster than Q5.

For example, 4 inches (100 mm) thick aluminium Q5 would be 0.72 in/min (18 mm/min) and Q1 would be 4.2 in/min (110 mm/min), 5.8 times faster.
