Conventional CNC grinding involves CNC wheel dressing with or
without direct component measurement useing either contact or non
contact laser measuring techniques. Grindind is then to a setpoint
dimension - lookup marposs and movomatic systems.

Some non conventional systems use self dressing (usually diamond
grinding where wheel dressing is difficult)however these machines
require very good stiffness with no compliance built into the
machine so that wheel breakdown can take place. Also the wheel has
to be designed specifically for the task in hand.
