Hello,

Very New to CNC. I cut the Plastic called Kydex (Mixture of PVC & Acrylic) that is .118" thick just under a 1/8". I cut all the way through with a 1/8" UpCut Carbide Bit from MLCS woodworking.

I tried Double stick tape & Carpet tape on top of my MDF sacrificial table & it sticks to the plastic just fine, but doesn't stick to the MDF very well.

Mat Material Question:
What do you use to hold your plastic pieces down... There is No way I can use clamps as the shapes come out to the edge of the material on all sides.

Speed Question:
I ran it at 100in/min 16,000 RPM with Double Stick tape = No melting or clogging, but had Chatter
I ran it at 80in/min 16,000 RPM with Carpet Tape = No Melting, But had Clogging, no Chatter

Rotation Question:
Climb cut Clockwise = chattered looking edges on the outside edges?
Climb for a slot was Counter Clockwise = Smooth edges ?



Thank you for any & all help


Sincerely,

Matthew
