We proposed an experimental method to study TBM gage cutter’s rock cutting process.
- class="label">•
The experiments were conducted on a full-scale rotary cutting machine (RCM).
- class="label">•
Wedges were inserted into the space between the cutter base and cutter box.
- class="label">•
The cutting forces of the gage cutters are smaller than the normal cutter.
- class="label">•
The depth of the rock broken zone is smaller than the cutting depth.
