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:
“And hiving wisdom with each studious year,
In meditation dwelt, with learning wrought,
And shaped his weapon with an edge severe,
Sapping a solemn creed with solemn sneer.”
—George Gordon Noel Byron (1788–1824)
“I am not naturally ... “A bag of wind”; yet ... I mean deliberately and decidedly “to cut” in future all my old ideas on this head. I don’t think modesty “pays.” It is a good quality in a family, it is a domestic virtue, it makes a home happy after you have got a home, but it is not potent in getting homes. It is not a money-maker, neither is it lucky in gaining a reputation. I am of the impression that gaseous bodies do better.”
—Rutherford Birchard Hayes (1822–1893)
