Default cutting plexiglass

I have a piece of acrylic 18x24 that is 1/4 inch thick. What I need is a piece cut 12X20.
If I cut this on my router table what would be the best bit to use and at what speed.

It's easier to make the cut on the table saw, and then threat the edge, if necessary, on the router table.

One more thing. Can I use a circular saw to make the first cut and then clean it off with a router for the precision.

I routed a backlit plexisign with a cnc-router and flame-polished it. It came out pretty well with a solid carbide, single spiral flute 3 mil bit. Had to slow down the feed at the ends, otherwise it cracks pretty easy.

Yes. A carbide blade designed for cutting plexi is recommended, however.
