My Build - I blame you lot for this....!

[HiltonSteve]

I have been profiling a couple of 20mm aluminium router sideplates at the weekend and been playing with different speeds and feeds to see find out what works best and gives the best finish.

Ended up at around 4000rpm with a feedrate of 600mm/min with a 2 fulte HSS slot drill, roughed the profile first stepping down 2mm at a time and leaving 0.5mm on all round, then did 2 finish pass's at 10mm deep with the same cutter but dropped the feedrate to 350mm/min, cutting time around 45 mins.

Finish is OK but still room for improvement, i have a couple of ali-master 10mm cutters which have completely different geometry to a standard slot drill so may give that a go to see if it improves the finish.

But overall still quite happy with the results!!
