I haven't needed to use them for a while but they are useful to know about to cut aluminium on a router table.

Re: [Emc-users] Mill ramp angle
Spiraling in, even without a predrilled hole there is much easier on the spindle and tool than a straight line ramp, because like Andy said you are only loading one side of the cutting tool and not cutting the full tool width. A full tool width cut is much more limited as far as maximum depth per pass than a cut that is only engaging a percentage of the tool. Todd Zuercher P.

Have some problem then mill enter material ramping down it wobble and torque increase. Diameter is 12mm and ramp angle is 10 degree. Anyone have any suggestion about this? Decrease ramp angle?
