Just remember that if you are using upcut spiral bit they are made for lifting chips from your cuts and they don't know the difference between a chip and your material.
As 4D said "You can make ledges that have a slightly sloped overhang to also hold down the parts while they are being cut." You can also do this to cam clamps.
Vacuum tables are great for face carving but not so good for cutouts unless the vac clamp is designed for the project so that the bit will not be cutting through the seals. Used correctly they can save a lot of time.
