One of the supports used to support the material you are machining. They are typically disposable. An alternate to slats, or a complement to them, is to use ceramic balls. It appears to be a good technique, especially for small parts that might otherwise tip or fall in-between slats. A more popular method for accomplishing this is also water jet brick. A common question is, "If the abrasive jet can cut just about anything, then how come the slats don't get cut?" The answer is that they do. As the jet cuts the parts, it goes right on through, and cuts the support slats. However, the slats are thin in the horizontal direction, and very thick in the vertical direction. What happens then, is that the jet gets part way down the slats, and then skips to the side, and does not cut the slat all the way through. Eventually, the slats wear until they look like a bunch of rusty needles. At this point, they are rotated to a less frequently used area of the table, and / or flipped upside down. Finally, the slats will eventually cut in half, at which point they are replaced. See also: Water jet Brick
A slat is one of the individual pieces of material (vinyl, metal, wood or fabric) that can be tilted to adjust the amount of light passing through the blind. It is often called a vane in a vertical blind.
Slat stands for "Sounds Like A Theramin". Slat allows you to use your mouse to adjust pitch and volume by waving the pointer over the interface. Tremolo and vibrato are adjustable. Slat is a JACK application.
