Tunnel boring machine cutters referred to as "TBM Cutters", are excavation tools installed on the cutter heads of tunnel boring machines and shield machines, which include TBM disc cutters (single disc cutter, double disc cutter, twin disc cutter) and soft ground cutters (eg. scrapers, cutting knives, buckets, rippers and other cutting tools).

Jan 31, 2024 · Tunnelling in hard and abrasive rock conditions, in particular, is adversely affected by a very low advance rate coupled with increased TBM disc cutter failures and cutterhead jamming, seeking an in-depth understanding of the design and operational processes of the boring components of the TBM.

Aug 1, 2021 · This study aims to propose four Machine Learning methods of Gaussian process regression (GPR), support vector regression (SVR), decision trees (DT), and K-nearest neighbors (KNN) to predict disc cutter's life of TBM. 200 datasets monitored during the Alborz service tunnel construction in Iran, including TBM operational parameters, geometry, and ...

Aug 1, 2022 · Disc cutters are representative cutting tools in tunnel boring machines (TBMs). They are installed at the cutter head of the TBM to disintegrate rocks during tunnel boring. Disc cutters require regular replacement to avoid wear and malfunctions.

In the tunnel boring machine construction, TBM cutters are indispensable tools, and all tunnel borer construction must be completed with these cutters. 1. Classification of TBM Cutter. TBM cutter can be roughly divided into TBM disc cutter and scrapers according to …

Feb 1, 2019 · Predicting the cutter consumption and the exact time to replace the worn-out cutters in tunneling projects constructed with tunnel boring machine (TBM) is always a challenging issue. In this paper, we focus on the analyses of cutter motion in the rock breaking process and trajectory of rock breaking point on the cutter edge in rocks.

The RingX ® TBM disc cutters were specifically created to significantly increase digging speed, drastically reduce maintenance frequency, and effectively optimize overall project costs, ensuring better performance even under the most challenging tunnelling conditions.

May 30, 2024 · In tunnel construction with tunnel boring machines (TBMs), accurate prediction of the remaining useful life (RUL) of disc cutters is critical for timely maintenance and replacement to avoid delays and cost overruns.

The rolling Disc Cutter is the most common cutting device in Tunnel Boring Machines and Raise Boring Machines when excavating massive or mixed rock formations.

Apr 21, 2025 · Tunnel boring machines (TBM) need to replace disc cutters to ensure the efficiency of tunneling, which relies on intensive labor operations in harsh environments, highlighting the urgent need for rob...
