Abstract: “Drilling is considered to be one of the mostly used processes for holemaking. Researchers have followed different approaches for the drilling simulation. Different mathematical tools offer a great deal of help in describing difficult 3D equations in space. Due to the continuous onward usage of CAD systems in all industries, new applications based on the Application Programming Interface (API) that each one offers, are under development. The present paper uses a general purpose CAD system and its API in order to create a kinematic model that parametrically controls the twist drill tool geometry. Introducing different tool parameters and cutting conditions, a series of 3D solid models for the tool, the workpieces and the undeformed chips are created and the resulted thrust forces can be predicted in both the main edges and the chisel edge. The proposed methodology is experimentally verified and provides the basis for a series of new applications in manufacturing”
