"Using a Fadal 4020 Vertical Machining Center to engrave & drill a synthesizer panel for my modular synthesizer. The spindle runs at 8000 rpm and 48 inch per minute feed rate. The cutter is a 1/8" carbide center drill. The CAM program was FeatureCAM by Delcam. The whole operation was done in about 4 minutes. Three carbide drills were used for the pot, jack and switch holes.
The panel is for an Oakley Deep Equinoxe phase shifter module designed by Tony Allgood of Oakley Modular Systems.

I bought the blank painted panel from Synthesizers.com. It would be better to use an anodized panel for this as the paint tends to chip away while engraving. The depth of the engraving would be less too. I usually have to clamp the panel and adjust the flatness to within 0.002" prior to attempting an engraving like this. I only engrave about 0.003" deep but it looks deeper due to the paint."
