Numerical simulation of workpiece thermal field in drilling CFRP/Aluminum alloy
TypeArticles dans des revues avec comité de lecture
Temperature reached at the tool/workpiece interface is difficult to measure during drilling operation, due to its enclosed configuration; numerical simulation is therefore a good alternative to access to this information. The purpose of this study is to develop and carry out numerical simulations in order to estimate the workpiece thermal field generated during drilling. The simulations are validated by comparing simulated and measured temperatures at 4 mm from the holes wall. This method is applied to evaluate thermal field generated during drilling (with chip removing cycles) of CFRP/Aluminum alloy stacks. The influence of the drilling kinematics on the workpiece thermal field is also investigated.

Evaluation of the performance of coated and uncoated carbide tools in drilling thick CFRP/aluminium alloy stacks MONTOYA, Maxime; CALAMAZ, Madalina; GEHIN, Daniel; GIROT, Franck (Springer, 2013)This paper aims to establish the wear mechanisms of coated and uncoated tungsten carbide drills when drilling carbon fibre reinforced plastics (CFRP)/aluminium alloy (Al) stacks. During the drilling experiments, thrust ...
A new material model for 2D numerical simulation of serrated chip formation when machining titanium alloy Ti-6Al-4V CALAMAZ, Madalina; COUPARD, Dominique; GIROT, Franck (Elsevier, 2008)A new material constitutive law is implemented in a 2D finite element model to analyse the chip formation and shear localisation when machining titanium alloys. The numerical simulations use a commercial finite element ...
