With plexiglass, how to cut it may depend on the tools you have on hand. If you only have one circular saw available, this is what you are going to use.
If, however, you have access to a table saw, using this tool is perhaps the easiest and most stable way to cut plexiglass.
Plexiglas is not glass. It is actually a type of plastic. With the heat generated by an electric saw, it melts.
To avoid this as much as possible, it’s best to have the right type of blade and not go too fast when making the cuts.
Step 1 – Measure the plexiglass
Measure the plexiglass with your tape measure before cutting. If the plexiglass is thin, using a table saw can be counterproductive as you risk severely chipping it.
I should score thin plexiglass with a utility knife and snapped in half instead of being cut.
Someone can safely cut 2mm thick plexiglass and more using a table saw.
Step 2 – Choose the saw blade
Plexiglas comes in two versions: rigid and flexible. Softer plexiglass can melt more easily, so it’s best to use a blade with fewer teeth to create less total friction when cutting.
A blade should cut harder plexiglass with more teeth in order to minimize chipping.
If you have different plexiglass to cut, try making all the hard cuts at the same time. Do the same with the soft cuts.
This way you will only have to change the blade once or twice. A carbide-tipped blade is the best solution.
Step 3 – Measure the size of the cup
Measure the size you want to cut and mark it on the plexiglass.
When you install the fence, the Best Table Saw For A Small Shop to hold the plexiglass in place, remember to compensate for the thickness of the blade so your workpiece is not too narrow. Lock the fence in place.
Step 4 – Use protective glasses
I always need safety glasses when using the Best Table Saw For Beginners, but especially when cutting plexiglass.
Small pieces of plastic can fly off, and you want nothing to end up in your eyes.
Step 5 – Make the cut
Turn on the saw and slowly advance the plexiglass through the blade, holding one end against the fence.
For very thin plexiglass strips, be sure to use a wooden safety guide to keep your hands a safe distance from the blade.
Take it easy. If chipping occurs, stop the cut and replace the blade with one with even more teeth. If melting, slow down to reduce heat.

Step 6 – Sand edges
If there is frost around the edges because of the melted plastic, sand it down with fine-grit sandpaper until it is as clear as you can get.
Also sand the splinters so that the edge is smooth.
Using the table saw is the easiest way to cut plexiglass, but if you don’t have the tool available, you can use other power saws as well.
