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:
“I believe the alphabet is no longer considered an essential piece of equipment for traveling through life. In my day it was the keystone to knowledge. You learned the alphabet as you learned to count to ten, as you learned “Now I lay me” and the Lord’s Prayer and your father’s and mother’s name and address and telephone number, all in case you were lost.”
—Eudora Welty (b. 1909)
“Brutus had rather be a villager
Than to repute himself a son of Rome
Under these hard conditions as this time
Is like to lay upon us.”
—William Shakespeare (1564–1616)
“The advantage of doing one’s praising for oneself is that one can lay it on so thick and exactly in the right places.”
—Samuel Butler (1835–1902)
