Drill wander patterns are analysed using a finite element model that includes the effects of transverse shear, rotatory inertia and gyroscopic moments. Co-compatible finite elements provide an effective method for obtaining transient drill path loci. Energy dissipation is allowed in the form of friction between the drill tip and work-piece. The analysis is limited to the motion prior to full penetration. Experiments were performed and the predictions of drill point wander patterns by the proposed finite element model show good agreement.
