Aug 26, 2019· Abstract: During excavation, the disc cutter (DC) of a tunnel boring machine (TBM) will experience wear. WInBot, a DC wear inspection robot, is developed for 5 m-diameter-class TBMs and two wear measurement methods are proposed. WInBot has a high expansion ratio actuator to allow operation in the narrow space around the cutter head.
