and the right blade.
I had reason to fit some 1/4 inch polycarbonate
strips into a sharpening center cabinet I'm making.
Cut to width - 10 inch length - with a dozuki saw
and found a) that I'd wandered off the line in places
and b) left a less than perfect surface on the edge.
Used a #5 on the edge and was pleased to find "see
through" curlies AND no tear out (the wonders of no
grain direction to deal with).

I have successfully used an Oldham plywood/particleboard blade, and I have a
s****y Crapsman TS. It cut just fine and gave a nice edge without chips
flying every which way.

A table saw and the blade depends on how many cuts are required.
A standard wood cutting combination blade will work if you are willing to
take your time.
If you try to push it, the plastic will heat up and give you a crappy cut.
If you have a lot of work to do, get a blade designed to cut plastic
materials. The specs are available from any decent plastics distributor.
BTW, just spent 2 hours this afternoon cutting up a block of UHMWPE to make
bearing plates.
Used a 50 tooth combo blade and very slow cuts to get the job done, but it
worked.

I have success with a triple chip grind negative rake 60 tooth carbide
blade.

I normally use my bandsaw. that way I don't have to change the blade on my
table saw.

_Good_ (low vibration) jigsaw with pendulum action. It's one of the
simplest demonstrations around for why a good jigsaw is better than a
bad one.

I have cut it with a regular cross cut carbide and like you said chips were
sent in every direction, but for what I needed at the time it worked ok.
Then tried a saber saw and that's when it melted back on to itself.. I will
have to try your method and blade.
Thanks

i use a triple chip style. its a bi metal cutting blade for alluminum
and other non ferous metals. if your lexan is thin say less than an
1/8" you can score with a knife and snap as you would with glass.

I use a Systimatic #1410 plastics/cutoff blade for this - it has 60
teeth, a very low hook angle, every other tooth has a flat top, and
the teeth in between are bevelled on both edges. If you use a
regular combination ATB or similar, your life will occasionally get
very exciting as your plastic parts go airborne.
Never really had the melting problem, maybe that's because I use a
full kerf blade and splitter.

I used to work for a neon sign company, and we'd used routers and CAD-based
tables with what looks like a router bit pointing downward (toward the table
from a moving arm) to cut lexan smoothly.
