I have a customer that wants me to cut some 3 inch thick acrylic, My bot has a 7 or 8 inch Z on it but I think I am going to need a longer end mill to go all the way through.
Is cutting acrylic any different than cutting any other substrate? I know speeds and feeds have to be right to stop the melting and so forth?? Any insight on where to get a 4 inch .25 or a .375 endmill?
