Default Machining Cast Acrylic sheets

My son has bought himself a CNC router and is setting up to make a product for sale. It involves machining cuts and grooves in 1/4" cast acrylic sheets.

He is using a single flute aluminum cutter in the collet and is not happy with the results. Too much melting and the edges are not smooth. He has dropped the rpm from 20K to 3000rpm and is feeding hard and still no joy. He is a bit anal about quality.
I am of the opinion that he needs a special cutter, but as I only machine nylon or delrin, I have no experience with this stuff.
Any advice I could give, he's already been there.
Any advice for the lad?
