If the machine is up to it, you should be able to get a resolution of <50um. Either shim up the low corners or compensate in software. (A discrepency of 50-100um across the PCB is usually OK, any more will require adjustment.) For cutting depth you want to be starting at 50-100um, which is 0.002-0.004 inches.

Milling a PCB - Johan von Konow

When the PCB is designed (see this post) it's time to prepare the board for manufacturing. I start by creating new layers for the mill paths. 1. Create mill paths. Offset pads and traces to create closed loops for the PCB. These loops are used to control the engraving tool to cut out the copper areas to save.
