Is Lexan a cast plastic? If not which is the best plastic to carve.
Lexan is a trade name for polycarbonate. It can be machined according to specs. Polycarb sheets are extruded.
Cast acrylic machines great. I have used both but with extruded sheet, I will usually use a coolant; small pieces, I’ll jus shoot some windex on the sheet every now and then.
Thx
I just finished a job using 0.188" Lexan - templates for a woodworking tool. I used a 1/8" 2-flute end mill, DOC of 0.03". 19,000rpm (3 on the 611), and feed rate of 20ipm. I got nice, clean chips, no burning, no dust. Due to the nature of its use, it had to be polycarbonate for its toughness. I tested at higher feed rates but wasn’t getting as clean a cut as I wanted.
Those look good, nice clean cuts.
That looks sexy

Sweet, Thanks Bill
What did you use to engrave the sizes?
That looks great Bill. What bit did you use to countersink the holes?
I set up two pocket cuts; one for the countersink that is 11/32" diameter and 0.078" deep ; the through hole is 11/64" diameter and cuts to 1/8" deep. I used a 1/8" 2-flute bit for all cuts.
