Hey Rex, there's actually a couple of solutions for laminate/melamine boards that are going to be rip cut. One is that you get them to over cut them and then re-cut the edges at half their thickness at the right size on each side which takes away the chipping which might not be something they're willing to do. Another solution (and really easy) is to get edge capping. It's a plastic material that you just snap install to the edge of your boards. Here's a link to a company that carries the U-Snap brand:

The thing is, even if you went with solution 1 or they cut it perfectly, you'll still be left with the rough crumbly looking edge and if you try to paint over that, it'll have a really rough texture. It's better that you take a strip of laminate and iron them on to conceal that but an edge cap would eliminate all of that work.
