... as ductile and soft. Comparison criteria are average normal, cutting, and side forces, specific energy, and yield. Preliminary results indicate that normal forces increase highly with increasing spiral number, which is important for thrust limitation of miners, while cutting force and specific energy...

... in obtaining the forces acting upon a cutter during its penetration and cutting of a groove in a sample of evaporite. These forces are transformed into Mechanical Specific Energy, MSE. The tests were carried out under different depths of cut and back-rake angles. The results indicate that MSE decreases...

... between February and March 2010, the rock samples were collected from 11 different excavation rings in the tunnel. The performance parameters of the tunnel boring machines (Cutter forces, i.e., thrust force, rolling force, and specific energy values) are also collected during the excavation of the tunnel...

... for defining point load index. Then, the uniaxial compres-sive strength values obtained from point load tests are correlated with TBM operation-al parameters such as torque, thrust, specific energy, as well as penetration rates. The results indicate that there is a moderate relationship between uniaxial...
