PCB milling uses a two or three- axis mechanical milling system to mill away the copper foil from the substrate. A PCB milling machine (referred to as a 'PCB Prototyper') operates in a similar way to a plotter, receiving commands from the host software that control the position of the milling head in the x, y, and (if relevant) z axis.

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.

PCB Manufacturing Process – A Step by Step Guide | PCBCart

The basic form of PCB comprises a laminate board whose core material is epoxy resin and glass fiber that are also called substrate material. Laminate serves as an ideal body for receiving the copper that structures the PCB. Substrate material provides a sturdy and dust-resistant starting point for the PCB. Copper is pre-bonded on both sides.
