The position of the grinding wheel surface relative to the machine axis positions continually changes due to grinding wheel wear, thermal expansion of the machine tool, and thermal expansion or contraction of the grinding wheel. […] The effect of this variability is that the wheel position stored in the CNC [computer numerical control] is inaccurate by the time it is necessary to re-dress the grinding wheel. To overcome this problem, the machine user often specifies a large dressing in-feed to guarantee that the dressing tool will dress the grinding wheel.
