a $100,000 cnc is very accurate an mdf home built cnc won't be near as accurate , the precision that you are aiming for is far beyond what most manufactured parts are toleranced for aside from bores and other special features but for general metal machining + or - .005 inch tolerance is fairly common , .1 mm is equivalent to 1/9 of the thickness of a piece of lined paper , so without understanding what types of parts you plan to make I would have to assume that the accuracy that you desire is unnecessary for wood or plastic
