Hi I am Jorge from South Africa.
I would like to know the best and fastest way to mill a oval 17.25mm hole x 92mm deep in aluminium grade 6082T6? I am using a Hurco VM20 CNC .
Thanks
Hello Jorge,
I wold drill the biggest hole I could in it. Then take a 16mm 3flute solid carbide mill, with 10mm depth of cut. Rough and finish the profile. Start out with a shorter mill then go to the longer one when you need to.
I will add a photo or two to show a tool I have that could work. I do knot know the geometry of the oval but you will need to use a tool smaller than the smallest radius of the oval.
You may need to do some plunge in z axis to rough it.

Something like this the one standing up is the best in my opinion.
