An experiment on ice cutting under high liquid pressure and 1ow temperature
In order to examine dependencies of hydro-pressure and ice temperature in ice cutting performance of a drill for deep ice coring, experiments on ice cutting were carried out under liquid pressure from 0.1MPa to 30MPa at temperatures of 12.3,-40.3℃ and -62.0℃ changing the rake angle of the ice cutter...
