This thesis presents a study on the development of a dynamic force model for drilling and reaming. It can predict the static forces, dynamic forces and vibrations under various cutting conditions. In this model, the cutting forces during drilling are determined by modeling the drill to consist of two distinct regions: the cutting lips and the chisel edge. The cutting forces due to the drill lips are modeled based on Oblique cutting mechanics. The tool vibrations are modeled based on the mechanistic approach and the effects of tool vibrations on the cutting forces are also modeled. Using this new force model, the chatter limits can be determined for the cutting process. The reaming model is then developed for reamers and it can estimate the static and dynamic cutting forces during reaming of holes. The reaming model can also model the forces at entry when holes have chamfer. The model for both drilling and reaming account for the effects of tool offset and tool asymmetry on the cutting forces. The model is robust and can be modified to accommodate other rotary machining processes such as milling. (Abstract shortened by UMI.)Dept. of Industrial and Manufacturing Systems Engineering.
