I have had good luck by making a scoring cut with the saw. I set the cut
to about 1/8" and then run the saw backwards across the plywood. Since, you
are making a very shallow cut, there is very little tendency for the saw to
climb out of control but keep a good grip on it. Then reset the saw for
full depth and make a regular cut.

The article is "A circular saw in the furniture shop"
is worth reading.

I usually make crosscuts of cabinet grade plywood, which are too large

my tablesaw, with my 7 ¼" circular saw. To avoid chipping the finished
piece I make the first cut a little long. I also always cover the cut
with
masking tape, but still get some chipping. I then cut to the exact size
using a straight cutting bit with my router. Using the router leaves a
perfect cut, but I have a project coming up that doesn't leave any room
for
an oversize cut unless I go to a second sheet of plywood.



Does anyone have any suggestions for cross cutting cabinet grade plywood
with a circular saw that eliminates chipping? I have tried different
blades, and cutting heights, but so far the best that I can get is about
95%. That other 5% can be a killer.
