Numerical investigation on the damage mechanism of CFRP drilling under different pretreatment temperatures based on bevel cutting

Abstract The widespread use of CFRP components in the aerospace industry has led to a significant increase in the demand for assembly holes, for which drilling remains the primary machining method. To effectively mitigate drilling-induced damage, this study simplifies the CFRP drilling process as oblique cutting and develops a temperature-dependent, three-dimensional microscale oblique cutting model based on the Johnson–Cook constitutive law, which is validated using experimental data.
