Effect of groove geometry and cutting edge in rock cutting
Published 2017“…A series of laboratory cutting experiments are carried out on two sedimentary rocks (a limestone and a sandstone) using a state of the art rock scratch device. The results confirm that the magnitude of the cutting force is directly correlated to the cross-sectional area of the groove. …”

An experimental study of the effect of back rake angle in rock cutting
Published 2018“…An extensive and comprehensive set of cutting experiments was performed on a wide range of quarry rock samples using a state of the art rock cutting equipment (Wombat). The results conform with the previous studies by other researchers; the intrinsic specific energy is in good agreement with the uni-axial compressive strength of the rock samples when the cutter is positioned at back rake angles between 5° to 20°. …”

Experimental investigation on the effect of wear flat inclination on the cutting response of a blunt tool in rock cutting
Published 2018“…An extensive and comprehensive set of cutting experiments was carried out on thirteen different sedimentary quarry rock samples using a state-of-the-art rock cutting equipment. A unique cutter holder was purposely designed and manufactured along with a precise experimental protocol implemented in order to change the back rake angle and therefore the inclination β by steps of 0.10∘ . …”

Analysis of rock cutting process with a blunt PDC cutter under different wear flat inclination angles
Published 2018“…For this purpose, an extensive and comprehensive set of cutting experiments was performed on two sedimentary rock samples (a limestone and a sandstone) using a state-of-the-art rock cutting equipment and a unique cutter holder. …”
