CNC Router for Aluminum mold creation?
I know nothing about CNC routers, but I'm curious about aluminum mold fabrication. Can anyone suggest a good instructable that would be useful in creating a CNC router that would be up for the job. The aluminum block is 4"x3"x1". It is completely blank so I need a router to remove the metal to create a mold. I'm not sure how accurate these things are, but it needs to be very accurate.
