Fig. 2 shows typical curves of one experiment with quartz stressed with a specific milling force of 4.1 N/mm 2 at a roller speed of 1.0 m/s. The step-shaped form of the curves is due to the reading frequency of the transient recorder adjusted to 1 kHz. With this fraction, only about six particles contact the sensor surface of 20 mm 2, therefore, the curves scatter statistically.
