I've been cutting glass plates and mirrors with my CNC milling machine machine for years. In this video, I describe a few tips and the general technique that I use.

Clamping the glass plate to the table is the critical part of the process, and so I built a jig that allows the glass to be held laterally with shims, but does not require a high clamping force, which would crack the glass.

Cutting parameters:

.085" dia diamond burr

3000 RPM

1-3 inches per minute feed

Cut depth .130" (full material thickness)

Flood coolant with soluble oil cutting fluid
