Hi,
I am a fresh newbie, currently working on milling off copper leads on computer chips. The whole square copper surface on the top of the computer chip has to be milled off. I'm using the EMCO Concept Mill 55 machine for CNC implementation. This machine is currently equipped with a 0.125" dia. 30 degree helix - rhs/rhc submicron grain carbide tool (http://www.garrtool.com/viewitempublic.jsp?edp=13070).
Can anyone suggest on how I should decide on the feed rate, spindle speed, and entering angle? Also, what is the shortest path for milling off a complete square surface? Currently, it's in simple zig-zag pattern.
I am totally new to this art and so any feedback would be valuable!
Thanks guys.
