What do I use to cut Acrylic?

What type of saw?
Typically you would use an over head panel saw, below table saw, or a table saw. For thinner sheets .177” or thinner you can use a jigsaw, band saw, or scroll saw. For thicker material you can use a band saw or jigsaw but the edges will be very rough. For thicker material table and panel saws are best. Whatever saw you choose there must be minimal vibration and enough power to make the required cuts. 

 

What type of blade?

A carbide tipped blade with a triple chip design is best. This type of blade will give you the most uniform cuts. For the longevity of the blade you should only use it when cutting acrylics.

 

What are the common blade diameters and tooth selections used for cutting acrylic sheet?

-         10” diameter, 60 and 80 tooth

-         12” diameter, 60,80, and 100 tooth

-         14” diameter, 60,80, and 100 tooth

Size and teeth per blade depends upon the thickness of the acrylic being cut. Thinner sheets require more teeth then the thicker sheets.

-         Chipping

-         Melting

 

Chipping        

Causes

Solutions

Feed rate to fast

Reduce feed rate

Incorrect number of teeth

Change blade, increasing number of teeth; optimum number of teeth is 80 for a 25.4 cm ( 10 inch) blade

Improper bade design

Change blade, use a triple chip No-Melt

Teeth out of alignment

Check alignment, change blade

Blade or Arbor wobble

Check run out, repair saw

Blade height incorrect

Adjust blade setting; review comments in Section II for correct positioning

 

Melting

Causes

Solutions

Feed Rate too slow

Check tip angle (60 degree)

Check rake angle (0-4 degree)

Incorrect number of teeth

Change blade, decrease number of teeth from 80 to 60 for a 25.4 cm (10 inch) blade
