Modelling Machining of FRP Composites

Machining of composite materials still represents a challenge in terms of controlling the process, especially to eliminate or minimise damage to the machined workpiece. Numerical models represent a powerful tool, usually used to investigate and optimize the process. For this reason, an overview of the state of the art of numerical techniques for simulating machining of composite materials at a macro-scale and micro-scale level is provided. Models based on the finite element method and mesh-free methods are discussed; advantages and drawbacks are highlighted. Finally, current models’ ability to predict chip morphology, chip formation mechanisms, machining force and damages in the ma-chined workpiece is discussed.
