Research and implementation of monitoring system of disc cutter rotation speed

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing
The disc cutter is a main cutter to break rock in the Tunnel Boring Machine (TBM), but its abnormal state will increase the wear and may even cause the damages to the cutter head. But the cutter wear can only detect the limit of tool use, Therefore, real-
