There are several ways to cut acrylic, but regardless of which method you use, you will want to prevent your cutting tools from becoming a source of damaging heat.*
Use a table saw, preferably with a carbide-type blade with 10 teeth per inch.*
Choose a saw blade that is designed for cutting acrylic. *
The blade’s teeth should be fine, of the same height, evenly spaced, with little or no set.* Be sure to feed the acrylic into the saw blade at a steady rate — feeding it too fast or too slow can cause the edge of the material to melt.
Thin pieces of acrylic (1/8″ or less in thickness) can be scored like glass using a scribing knife, metal scriber, awl or utility knife, and snapped apart.
Note:
This process does not work well for long cuts and may not leave an edge that is flat enough for capillary gluing...
it will chatter and ''grab'' your plastic...
you need to remember that acrylic is nick sensitive and the nicks will cause/lead to cracking/splitting under tension/compression....

the 40T blade is a poor choice...
