For 1/16 and larger plastic cuts I really like the onsrud single flute
cutters, I am sold, even at $40 plus for larger ones.

Ye Steve is correct. I machine the soft plastic in these cases. The spindle
speed is 1000rpm or less with a single flute 1/8" bit.

Must be a slow
Oops, I missed that part. Your feed/speed make more sense now. I'd still be
tempted to use a v-bit for that part and a 'V-Carve/Engraving' toolpath.
While it's a bit on the small side, it *should* give nice clean corners too.
It depends if your script will handle the Z motion correctly for that
too
Yes, but.. a .020" snaps if you look at it wrong.

That seems extremely slow. I can't see a mention of what the plastic you're
cutting is but for Corian or acrylic with a 60 degree v-bit I tend to run at
around 1800 mm/min, 3mm DOC, 16k to 20k on the spindle - I adjust that by
ear.
I would run faster - but my router caps out at 2000 mm/min.

I'll try that. I am currently cutting .015" deep, probably around 32000
rpm and 15 ipm.

Make sure that your spindle speed is as slow as you can go with it. I
found to get a neat clean cut with plastics, I have to turn the speed
way down. The feed can be fast. You want to get nice chips. If you go
too slow or the spindle speed is too high, the plastic tends to melt at
the edges ins
Hmm. I wonder how many folks who own a cnc router would let somebody else
do something like this? My bro-in-law has a laser engraver, but to get a
paintable depth would take a lot longer than the 20 seconds per but its
taking me.
So the suggestion is that a v bit is not going to curl the edges t

I wrote my own script to handle the curved surface. I wrote a custom post
processor for this as well, it works well enough for the button curve.
I am using the Create Vector tool within vcarve.
This is getting infilled with black enamel, and cleaned once dry with
Naptha.
I did a number of these
Send me the artwork and I will run it through EnRoute, which can handle 3D
engraving on a curved surface much better. Depending on the plastic you
will probably be happier with an engraving tool with a small tip (.001 or
.005 need to see the artwork) That tip gives you a little rotation to

Are you creating it in VCarve Pro by using the Quick Engrave tool or the VCarve
tool?

I am routing some lettering on some small plastic buttons with a .020 ball
nose feeding at 15 ipm. I am using vcarve pro to create the lettering,
using Norm West 1L, or a single line font. I am using create profile, on,
