Cutting is an important process in the manufacturing industry. It is necessary to use good
quality cutting tools in order to maintain the quality of a product. The coating on a cutting tool …

Wear characteristics of disc cutter can vary significantly during shield tunnelling in different
geological formations. This paper presents a case study on disc-cutter wear experienced …

The grain-size dependence of wear resistance of WC-Co cemented carbides (with mean
WC grain sizes of 2.2 μm, 1.6 μm, 0.8 μm and 0.4 μm, respectively) was investigated under …

Artificial fractures on the tunnel face can promote tunnel boring machine (TBM) performance
in the intact rock mass with high rock strength. High-pressure water jet (HPWJ) is a feasible …

Three constructional solutions of coulters used in cultivators were assessed with regard to
their wear resistance in soil. The coulters were installed on a four-beam cultivator used for …

During soft ground tunnel construction, the presence of sandy gravel stratum often causes
serious wear and tear of cutting tools. In this paper, an experimental study to assess …

In this study, investigations were conducted to evaluate a new type of rapid treatment
designed to alter the microstructures of cemented carbides for improved milling and …

The wear phenomenon evaluation in EPB shield tunneling machines is not a simple issue,
as a large number of parameters are involved, such as soil and tool material properties, soil …

Prediction and analysis of cutting tool wear in dense sandy ground is important for improving
the working performance of slurry shield TBM, especially for long-distance cross-river tunnel …

When shield TBM tunneling in abrasive sandy ground, scrapers are loaded with heavy
forces resulting from the extrusion and friction processes of sand particles. Scraper wear …
