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.

Pinching and poking my thin ribs
Till I lay in their laps, laughing,
Weak as a whiffet;”

The secret mischiefs that I set abroach
