The rapid growth of a modern industry results in a growing demand for construction materials with excellent operational properties. However, the improved features of these materials can significantly hinder their manufacturing, therefore they can be defined as hard-to-cut. The main difficulties during the manufacturing/processing of hard-to-cut materials are attributed to their high hardness and abrasion resistance, high strength at room or elevated temperatures, increased thermal conductivity, as well as their resistance to oxidation and corrosion. Nowadays the group of hard-to-cut materials includes the metallic materials, composites, as well as ceramics. This special issue, "Advances in Hard-to-Cut Materials: Manufacturing, Properties, Process Mechanics and Evaluation of Surface Integrity" provides a collection of research papers regarding the various problems correlated with hard-to-cut materials. The analysis of these studies reveals primary directions regarding the developments in manufacturing methods, and the characterization and optimization of hard-to-cut materials.
现代工业的快速发展导致对具有优异使用性能的建筑材料的需求不断增长。然而，这些材料改进后的特性会显著阻碍其制造过程，因此它们可被定义为难切削材料。难切削材料在制造/加工过程中的主要困难归因于其高硬度和耐磨性、在室温或高温下的高强度、增加的热导率以及抗氧化和耐腐蚀性能。如今，难切削材料类别包括金属材料、复合材料以及陶瓷。本期特刊《难切削材料的进展：制造、性能、加工力学及表面完整性评估》汇集了一系列关于与难切削材料相关的各种问题的研究论文。对这些研究的分析揭示了制造方法发展以及难切削材料表征与优化方面的主要方向。
