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:
“Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal: but lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal: for where your treasure is, there will your heart be also.”

“The grief of the keen is no personal complaint for the death of one woman over eighty years, but seems to contain the whole passionate rage that lurks somewhere in every native of the island. In this cry of pain the inner consciousness of the people seems to lay itself bare for an instant, and to reveal the mood of beings who feel their isolation in the face of a universe that wars on them with winds and seas.”
—J.M. (John Millington)
“The unbosoming oneself to another is a kind of release to the soul, which strives to lighten its burden and find ease by throwing off the weight that lay heavy upon it.”
—François, Duc De La Rochefoucauld (1613–1680)
