1. ramping is used especially when you have an endmill as they are not centre cutting and therfore cant plunge in. Yes I know you get centre cutting endmills but are they really endmills or just 3 and 4 flute slot drill
2. Alu, especially the softer grades are a PITA and possibly faster feeds may help.
3. Probably spindle deflection, I get this on the Bridgeport, partly because there is some wear in the bearings but mainly because Bridgeports are about as rigid as a piece of string
