Finite Element Analysis and Experimental Investigation on the Conventional and Vibration Assisted Drilling
نویسندگان
چکیده مقاله:
In this research, finite element analysis of the conventional drilling and vibration assisted drilling is carried out. The ABAQUS software is employed for FE analysis. The Johnson-Cook models for both plastic deformation and damage are employed for FE simulation.The results of the FE analysis are then verified with experimental results in both conventional and vibration assisted drilling on Al 7075 with HSS drill in terms of the drilling axial force and torsional torque. There is a good agreement between the experimental results and the FE simulation results. The results also show that the drilling axial force and torsional torque are reduced in vibration assisted drilling in comparison with that in conventional drilling process. The surface roughness of the holes is also studied in conventional drilling and vibration assisted drilling. The results showed that the surface roughness is exceled in vibration assisted machining in comparison with that in conventional drilling.
