Polywood is HDPE that is treated to resist fading in sunlight. The only question in my mind would be is the piece solid or hollow.
HDPE can be used on a CNC router; you’ll need to use feeds and speeds (and bits) compatible with plastics.

That is recycled plastic, I believe PE, so it cuts like HDPE — see the videos on plastics at:

Yes, one could cut polywood so as to make a sign on a CNC machine using suitable tooling and feeds and speeds.
I was replying to Eric’s comment that wood is wood, when in this case it isn’t.
Woah! My apologies, as usual My poor vision, slight dyslexia and lack of taking the time to look more closely, I have misread the question. I was reading plywood, and yes that is wood. But technically My statement of yes is still correct, POLYWOOD or HDPE can be cut on a CNC.
Yea you can use plywood. Just make sure you pay attention to the different levels between the layers. Also there is more chances of having voids and various types of wood under the top layer. Make sure to use downcut bit. I use plywood for most of my flags.
