Here's a video of my shop-built CNC router cutting a connector cutout. The material was 0.090" 5052-H32 aluminum. This material cut be a bit tricky to machine because it is fairly soft. The Micro-drop coolant provided just enough lubrication to keep the tool clean and the chips removed. I was using the MD-7 synthetic coolant.

Below is the same pattern cut from a 0.060" thick extruded panel. This material is very gummy, but as you can see the resulting cut was very clean.
