Ideas for machining this?

Joules:
Lets try from a different angle.  I have been doodling, what shape is the follower that contacts this cam.  Is it spherical, a straight or taper pin profile.  From that I can sweep the cam surface to form the ramp.

Pete.:
I'd draw that in CAD as a 2-d ramp and plot x,y co-ordinates for step-milling with a ball end mill, but put the part on a rotary table and turn the part instead of moving in the x axis.

I think with a bit of fiddling this can do it but I am feeling so bad now i can't think straight will revisit it tomorrow hopefully.

Joules:
Take it steady Shipto, no need to rush.

Deko:
If the angle you need to cut is 45 degrees, then use a 90 degree spot drill to mill the area.  :beer:
