Figure 6. Grey scale images of the density (left), main cutting force (middle) and feed force (right).
Frozen(row 1), non-frozen(row 2). Edge sharpness 5 um.
The scale factors and mechanical zeros are chosen as follows:
Main cutting force 0-255 in grey scale corresponds to 0-85 N, 0 = 0 N.
Feed force 0-255 in grey scale corresponds to +/-15 N, 127.5 = 0 N.
Density 0-255 in grey scale corresponds to 0-1690 kg/m3, 0 = 0 kg/m3.
