Also, a part of the layout has cuts of 2mm width which I obviously can't be made unless the drill bit diameter is 2mm or less. So that's also a problem....as I remember 2mm or less diameter drill bits are usually used for PCB cutting only...So that's the reason I'm prefering laser, plasma or water jet.
From 1.0mm onwards, drill bits are available in 0.1mm increments. I use 1.8mm, for example with ordinary drill machines. For modeling with CNC Lasercut (plastic), mine has a precision of 0.01mm movement. One possible solution is to mark (engrave) the layout on a plastic CNC Laser cut and then manually make the cuts (or on a vertical milling).
PCB drilling (CNC) use very high speed spindle (around 60,000-150,000 RPM) and use special material drill bits but those are only for FR-4 materials. Those PCB drilling machines can't handle MS sheets.
