CAD Based Drilling Simulations for Al7075

Abstract:

Drilling is considered to be one of the mostly used processes for holemaking. Researchers have followed three different approaches for its simulation i.e. analytic, experimental and numerical. Nowadays the direct access of scientists to the Application Programming Interface (API) of several CAD systems led to an increased number of finite element simulations based on CAD 3D models of drilling tools. The present paper uses a CAD system and via its API a kinematic model is created. Different tool parameters and cutting conditions are introduced; a series of 3D solid models for the tool, the workpieces and the undeformed chips are created and the resulted thrust forces are predicted in both the main edges and the chisel edge. The proposed methodology is experimentally verified using Al7075 for the workpiece and HSS for the tool material. In addition, it provides the basis for a series of new applications in other manufacturing processes based on CAD created geometries.
