Edge Quality
Edge quality for water jet cut parts is defined with the numbers 1 through 5. Lower numbers indicate rougher edge finish; higher numbers are smoother. For thin materials, the difference in cutting speed for quality 1 could be as much as 3 times faster than the speed for quality 5. For thicker materials, quality 1 could be 6 times faster than quality 5. For example, 4″ thick aluminium Q5 would be 0.72 ipm (18 mm/min) and Q1 would be 4.2 ipm (107 mm/min), 5.8 times faster.

Famous quotes containing the words edge and/or quality:
“We hear the Secretary of State boasting of his brinkmanship—the art of bringing us to the edge of the abyss.”
—Adlai Stevenson (1900–1965)
“If behind the erratic gunfire of the press the author felt that there was another kind of criticism, the opinion of people reading for the love of reading, slowly and unprofessionally, and judging with great sympathy and yet with great severity, might this not improve the quality of his work? And if by our means books were to become stronger, richer, and more varied, that would be an end worth reaching.”
—Virginia Woolf (1882–1941)
