The UDOO is a single board computer with a 1ghz quad core CPU plus an Arduino
DUE. Same CPU as the Raspberry Pi but with 4 cores.
Runs Linux and Android.

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 did a quick search in my archive and there are a couple of relevant
pictures of the lens shape and a mold
there may be more when I get around to doing more scanning

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

If you can't fix it, you don't own it.

How are molds for plastic reflectors machined? They have a large number of
sharp edged corner cubes.
Could be done with EDM, but how would the EDM electrode be machined? All those
small facets have to be polished for the reflector to reflect light.
Plastic reflectors have been made like this as
