Abstract A scaled rock cutting test is presented. It is designed as an attachment for hydraulic presses commonly available in rock mechanics laboratories. Rotating disc cutters are used to cut rock samples several times with the possibility to adjust indentation depth and spacing. Standard sample sizes, which are available in early phases of a tunnelling project, are used in order to enable this test to be used for tunnel boring machine (TBM) performance prediction. The results are compared to geotechnical standard tests (uniaxial compression, Brazilian tension), full-scale linear cutting tests and TBM operational data. It is shown that scaled rock cutting tests are superior input parameters for TBM performance prediction compared to commonly used geotechnical standard tests.
