Drilling of biocomposite materials: Modelling and experimental validation

Induced damage during biocomposites drilling is significantly different to that produced on composites based synthetic reinforcement such as carbon or glass fibers. In reinforced with fibers, induced increases feed rate, however was observed decrease rate in natural This work focused the explanation of this differences between and traditional effect strain material behavior machining. A FEM model has been developed ABAQUS/Explicit verify hypothesis. numerical used explain found influence main parameters drilling. Experimental tests were conducted validate through comparison thrust forces factor for two drills geometries Flax/PLA bio composites. The results indicate only predicted when constitutive accounts experimental type Additionally, demonstrated ability reproduce cutting conditions (cutting speed, feed, thickness drill geometry)
