The emergence of fibre-reinforced composites can be regarded as a significant breakthrough in the development era of new materials in human society. This can be seen by their substantial impacts on the material distributions in diverse industrial fields due to their superior mechanical/physical properties and flexible structural functionalities. To meet the eventual application requirements, machining operations such as milling, turning, drilling, etc. are required to precisely fabricate these fibrous composites.

In spite of their widespread applications, composite materials are rather difficult to cut due to their anisotropic behaviour and heterogeneous architecture. Particular issues in composites machining are associated with severe defects formation, rapid tool wear progression, and short tool life, resulting in a large number of part rejections. To solve fundamentally the technical issues, experimental and theoretical investigations devoted to investigations of cutting mechanisms, process parameters optimization, wear prediction, and management are of vital importance.

This Special Issue aims to collate original research and review articles that report on the newest studies in the fields of various machining processes for fibre-reinforced composites, covering a variety of aspects including the mechanical modelling of force and heat generation, optimization of process parameters, numerical modelling, damage detection, wear prediction and control.

Potential topics include but are not limited to the following:

• Chip removal mechanisms of composite materials
• Conventional machining techniques involving turning, milling, drilling, etc.
• Hybrid machining operations for composite materials
• Mechanistic modelling of force and heat generation
• Optimization of process parameters in cutting composites
• Numerical simulation and FE analysis of machining composites
• Composite damage characterization, detection and quantification
• Wear prediction and control for composites machining
