===== Machining Small Objects=====

When machining blanks that are not large enough to use vacuum, clamps should be used.  
There is a set of clamps. The set consists of clamping bars, adjustable height blocks, T slot nuts, studs and nuts. (17mm)
If the part is to be completely cut out, a spoil board is needed.  The spoil board’s size need to be larger than the footprint of the blank, and small enough to work within the T slot rails.
Place the blank onto the small spoil board and position at least three clamps.  There are breaks in the T slots on the machine bed for the slot nuts to be inserted and slid into position.

Defining the new Zero height.

A change in spoil board requires a recalibration of the zero height.
Use FUNCTION 28 to set the height of the spoil board.
MAKE SURE THE TOOL HAS BEEN QUALIFIED BEFORE PERFROMING A FUNCTION 28.
Bring the tool down to touch off the height of the spoil board.
