3.4.3 Processing table
The material is placed and affixed on the processing table and is subsequently
processed by the processing head. The processing table has a reference-hole system
with two dowel pins on an exactly defined line. These enable to produce double-sided
PCBs precisely, even without a camera. Match-up of the top and bottom layers is
achieved by the dowel pins.

3.4.4 Vision system
The system can recognize the fiducials on the material with the camera and thus
measure the material exactly. Furthermore, the camera can be used to check the
milling width result and thus the milling width adjustment.
