I agree with Ataxy and Usama.
Plain and simple
- a 3 axis machine can move ALL 3 AXIS SIMULTANEOUSLY.
- a 2.5 axis machine has a z axis that is CNC controlled to be used for drilling and positioning to desired depth of cut. A carefully programmed 2.5D process will make parts as good as doing it in 3D. Lets call this "CONSTANT Z LEVEL CUTTING". You can make undercuts perfectly fine with 2.5D as well.
- a 2 axis machine has NO CNC CONTROL over the z axis and must be manually positioned. IMO this type of machine is a waste of good money
