Mike,
Depending on the material type a different cutter will be used. Normally the guys charge for machine time so the cutter size is very important. I use 12mm or 0.5″ special cutters for laminated materials. The rule of thumb is to cut no more than 80% of the diameter in one cut. Again this is dependent on the cutter type. Normal straight fluted cutters, no mare that 50%. I.e. if you use a 8mm cutter you would do 4mm passes.
Next, if the machine has a vacuum bed for holding the job, you can get pretty close between the parts. If not, you want to make sure that the parts don’t come out before the job is done. For this you include what we call tabs. It is a piece of material left uncut on the outer edge of all parts. You decide the spacing but what it does is to keep the parts stuck to the material until you manually break the tabs and release the parts. If you cut this way, you need more flesh between the parts.
