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.

“Lay down, lay down the bigly bier,
Lat me the dead look on;
Wi’ cherry cheeks and ruby lips
She lay an’ smil’d on him.
O ae sheave o’ your bread, true-love,
An’ ae glass o’ your wine,
For I hae fasted for your sake
These fully day [is] nine.”
