 +900 g Al round block
 +  * P180 / 80 um used SiC: 140 mm3 / sec @ speed 3
 +    * 460 - 423 = 37 um / min
 +    * 5.3 x 11.0 mm = 58.3 mm2
 +    * 37 * 4 * 58.3 = 8628.4 mm3 / min
 +    * One die fractured after just one minute
 +    * Probably too aggressive to use in practice
 +  * 30 um new AO: 6.2 mm3 / sec @ speed 3
 +    * Same area as above
