Following Challenges: I should mention that this is a 1200*900*700 mm Machine

also is milling Possible with lets say a laser cutting machine? Or laser CNC machine are basically a 2 axis Machines, and one just can not control it in Z direction?
otherwise is a process like are clearance possible with laser CNC Machine?
