6) Fly cut the surface of the spoil board, removing approximately 0.060" to
insure that the compressed surface of the material is removed.
7) Once the material surface is machined, turn off the vacuum pump, turn
the spoil board over and repeat the process for the other side.
(Remember to ensure that the table and spoil board are clean.)
Spoil Board Use
Each time a new job is machined, there may be shallow cuts into the spoil
board in the areas that the cutter passes through the material.
Prior to placing a sheet of material on the spoil board, clean with a hand-held
blower or vacuum cleaner. Dirt under the material will reduce the vacuum,
and in extreme cases, parts may move during the machining process. In
general keeping everything clean is the key to achieving good, repeatable
results.
Precautions Regarding Spoil Boards
The spoil board is porous and will absorb moisture. As moisture is absorbed,
the dimensions of the board will change. In general this will not be a problem,
as the changes from day to day are not that excessive and will typically be
over the complete board. There are, however, exceptions.
It is a good practice to keep material on the top surface of the spoil board
overnight to prevent warpage due to uneven moisture absorption by the
material.
Also, once a spoil board has been used and has kerf cuts that resulted from
machining parts, it is a good idea to fly cut the surface again. This time it
should only be necessary to remove 0.015" of material since the only purpose
is to produce a smooth, flat surface, and that amount should remove the
machining marks.
The spoil board must cover the complete table and sit on the flats around the
table. If the spoil board does not cover all the vacuum slots, the vacuum may
be lost and the panel material will not be pulled down onto the spoil board
effectively.
