Hello gang. I want to cut 3/8" and 1/2" marble tile with my cnc router and am looking for suggestions on tooling required, feed speeds, and cutting rpm. The marble will be cut through and I am using a PC 5 speed 3.25 hp router and have 1/2, 1/4, and 1/8" collets available, also using mach3. Any help would be greatly appreciated.....Thanx
