To do it right you would need a machine with a scoring blade otherwise it will splinter on cross cutting.

Some recommend taping the cut line before cutting but I haven't tried that myself as I have access to a machine with a scoring blade.

An alternative you might try is having it cut oversize and then trimming with a router.

It should only splinter on one side so you may be able to make allowances for the splintering by ensuring it is hidden on assembly..

Don't believe anyone who says they have a magic blade that doesn't splinter. If such a blade existed industry would not spend money on machines with scoring blades.
