Lay
Lay is a measure of the direction of the predominant machining pattern. A lay pattern is a repetitive impression created on the surface of a part. It is often representative of a specific manufacturing operation. The lay may be specified when it has an effect on the function of the part. Unless otherwise specified, roughness is measured perpendicular to the lay.

Famous quotes containing the word lay:
“O but there is wisdom
In what the sages said;
But stretch that body for a while
And lay down that head
Till I have told the sages
Where man is comforted.”
—William Butler Yeats (1865–1939)
“I cannot choose but weep to think they would lay him i’th’
cold ground.”
—William Shakespeare (1564–1616)
“Be it so, for I submit; his doom is fair,
That dust I am and shall to dust return.
O welcome hour whenever! Why delays
His hand to execute what his decree
Fixed on this day? Why do I overlive?
Why am I mocked with death, and lengthened out
To deathless pain? How gladly would I meet
Mortality, my sentence, and be earth
Insensible! how glad would lay me down
As in my mother’s lap!”
—John Milton (1608–1674)
