I have the opportunity to supply a customer with several hundred 7" x 22" screen printed signs. The problem I am facing is that the signs will need to be shaped...a rectangle with a point on one end. It's too many to hand cut and not enough to justify die charges (that I'm aware of). Has anyone had success in cleanly cutting 4mm coroplas with their CNC using a specific router bit or by using a specific blade for plotting the blanks? I am using a Gerber 408. Any suggestions will be appreciated very much!

I have had real good luck using Onsrud and Centurion O-Flutes at 8 ips 5 sheets at a time at 18000 rpm.

Use a new bit older bits will leave dingleberrys.

Spring Clamps and ill hold the shape down with a dowel/stick or whatever I find...

Or I'll leave about a 1/2 bridge at the end and just cut them out with a knife

Bryan, if you try Bill's method on your Gerber please post how it works out. We've got a Sabre 404 and would like to rout coroplast on occasion.
