The change from traditional woodworking methods to CNC routing brings many advantages, some of which are not always obvious.
Of course, output potential is greatly enhanced but this is not the biggest immediate advantage gained.
Without doubt, a CNC router's ability to produce parts at a high rate and also a very high level of repeated accuracy is what is most noticible.
This high level of repeatability and accuracy gives the benefits of much easier final assembly and a tremendous reduction in scrap, rejects and time.
