Good Evening to All
Its been quite a while since my last post, just goes to show when you build a good Mach machine nothing really goes wrong, True to a point, since last time I posted anywhere, I have added a 4th axis to the big router, and actually worked out how to use it, still trying to learn how to alter a 3d file but that is a different matter entirely.
Ok enough rambling from me, My next project is to make a 23' Aluminium boat, the panels I am hoping to cut using my CNC router, I can already hear shrieks out there, apparently it can be done. The thickest material will be 6mm and the rest will be 4 and 3.
The machine has a 5HP Fimec motor speed range from 7 to 14.700 rpm and cuts max speed 3000mm/min comfortable, can go a lot faster but scary at high speeds! I don't want to use mist lube on the cutter I have made up a concentrated compressed air fitting to blow onto the cutter, but I don't want oil going all round the joint.
I will probably use either a 3mm or 6mm cutter cut down, smaller the better.
Now the Crunch, What I would like to know What is be best cutter to use? speed/feed rate? rpm? and cut depth?
Has anyone got experience?
