Résumé

The machining of thin wall parts remains a challenge in industry especially at High Cutting Speeds. In this paper the static deflection of thin walled parts during Dry High Speed Machining was studied. The problem was solved using the finite element method. The material removal during the cutting process was simulated using standard packages in ANSYS. The new introduced method is based on parameterized work piece geometry that was updated continuously during the cutting operation. A purely geometric criterion was chosen to initiate material removal. The cutting forces were estimated using a predictive cutting force model including material constitutive equation. The cutting forces were distributed uniformly in the tool-work piece contact zone. Full immersion peripheral end milling tests were performed for different cutting conditions. The model generated the work piece static displacements during the cutting process. The proposed method is found to be easier and more rapid than existing methods in the literature.
