Angular dependence of rock cutting forces due to foliation

A series of rock cutting tests was conducted with three different metamorphic rock types. Samples were prepared with alpha angles of 0°, 45° and 90° to investigate the influence of foliation angle on the rolling forces (FR,scaled) of a mini disc cutter (scale 1:8). Results show that FR,scaled increa...
