CAD Modeling and Optimization of the Optimal Geometric Features of a Microdrill

Abstract:

The objective of this paper is to construct a CAD model and to determine the optimal geometric features of a 0.1 mm diameter of microdrill. The CAD model was constructed using Pro/Engineer software by determining the flute of a microdrill mathematically. The cross section comparison between the model and fabricated microdrill was carried out by cutting at different lengths, and the results of the web thickness of the model and the fabricated microdrill were approximately the same. Hence, the CAD Modeling of a microdrill based on determining the flute mathematically by considering both setting angle and profile of a grinding wheel was feasible. The optimal geometric features of a microdrill have been determined by carrying out optimization of the stress/displacement analysis using Pro/Mechanica software so that the maximum stress Von Mises of the microdrill was minimal.
