Machining carbon fiber reinforced polymers (CFRPs) is facing huge challenges due to
the generation of crucial damages, posing a fatal impact on structural performance
and accuracy. To date, numerous studies have been performed to address the damage
issues associated with cutting CFRPs through experimental and numerical ways. However,
no review articles are reported so far to summarize the state-of-the-art advances
achieved in the numerical modeling of cutting-induced damages for CFRPs. To fill this
gap, this paper firstly overviews the fundamental characteristics of cutting-induced
damages for CFRPs and then summarizes the potential numerical methods applied for
CFRP machining. A particular focus is placed on detailing progress of the constitutive
models, failure criteria, definition of tool-chip interaction and frictional behavior
for CFRP machining. Moreover, a rigorous literature survey was conducted to report
the recent advances in the modeling of orthogonal cutting damages and drilling-induced
damages for CFRP composites. The thermo-mechanical effects and parametric effects
on the cutting-induced damages as well as the numerical quantification/assessment
are illustrated. Eventually, the future perspectives concerning the numerical prediction
and estimation of cutting-induced damages for CFRPs are outlined. The paper can benefit
both academia and industry to realize damage-free cutting of CFRP composites.
