Plunge rate and diving angle

How can I adjust the plunge rate? When I cut the rate into half, the ramp itself does not change (just the speed). With wood I would not bother. But with aluminium, I often break the bit when I can’t lower the diving angle.

Maybe this is a bug in ease-down? It should use the Z plunge rate instead of the XY feedrate.

The choosen feed rates are correct:

G21
G90
G0 X7.5875 Y7.5875 F6000
G0 Z2.0 F2000
G1 X10.4125 Z0.5875 F20; --> dive
G1 Y11.1749 Z-2.9999
G1 Y24.4125 F300;        --> mill
...

But I’m looking for a less agressive diving factor.
Perhaps with with ease-down the diving speed is equal the xy speed and the plunge rate affects the diving angle?

G0 X7.5875 Y7.5875 F6000
G0 Z2.0 F2000
G1 X10.4125 Z0.5875 F300; --> dive with xy feed rate
G1 Y16.0 Z-2.9999;        --> expand diving path from Y11.1749 to Y16.0 or so...
G1 Y24.4125 F300;         --> mill

Older code used to interpolate between XY and Z feeds on ease down / contouring. It caused some trouble, so I backed it out. It will be re-introduced with a new algorithm probably in this dev cycle.
