That's the only accurate way to do it with a given tool, material and a particular depth of cut. Just touching the work or a plate will get you near, only actually taking a cut will give you an accurate figure. In production CNC work, generally, the first part is scrap. It's measured and then adjustments are made to the tool offsets, a second part is run an if you are good/lucky - it's on tolerance and the parts run is commenced, parts are measured regularly and wear offsets applied as production progresses until the tips are worn then replaced.
