Setting the correct V RAMP settings for V carving

[nick]

I have my VRAMP settings in tune with 3D machining pretty good, but am having difficulties with my setting for V carving small letters.

Too many fast movements around small areas...machine jerks, and tool marks are visible on the cut edge...very jagged.

What would the optium setting for V carving small letters averaging .75" in height.

Below are the setting I am using...

90Deg 1.25 Cutter
3D RAMP THRESHOLD = 100
Min DIst to Check = .100
Move ramp rate = .2
SLOW CORNER SPEED = 45
RPM = 12000
X,Y Speed = .7
Z Speed = .7

Any help for clean carvings

Regards,

Nick

Nick,
Try these:
min dist to check: 0.08
slow corner speed: 50
xy move ramp speed: 0.1 or 0.2
z move ramp speed: 0.1 or 0.2

Nick,
Try those settings above. Your other numbers look fine. Read Brady Watson's article on Ramp Values. He explains it very well in his article. Helped me out tremendously.
