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:
“It was her stern necessity: all things
Are of one pattern made; bird, beast, and flower,
Deceive us, seeming to be many things,
And are but one. Beheld far off, they differ
As God and devil; bring them to the mind,
They dull its edge with their monotony.”
—Ralph Waldo Emerson (1803–1882)
“Although good early childhood programs can benefit all children, they are not a quick fix for all of society’s ills—from crime in the streets to adolescent pregnancy, from school failure to unemployment. We must emphasize that good quality early childhood programs can help change the social and educational outcomes for many children, but they are not a panacea; they cannot ameliorate the effects of all harmful social and psychological environments.”
—Barbara Bowman (20th century)
