Abstract

A dynamic model of the cutting force system in the turning process is developed. The model, which describes the dynamic response of the tool holder and workpiece using distributed parameter models, as well as the varying chip geometry and its effects on the cutting forces, can be used to predict the dynamic cutting forces for the turning process. The model, as implemented as a computer simulation, can be used to evaluate process stability and predict surface error, surface texture, and peak cutting forces. The model incorporates the effects of the cutting conditions, tool geometry, and process excitations such as workpiece inhomogeneity and changes in the chip load due to intermittent cutting. The model was used to predict the cutting forces for the machining of a workpiece with a large length-to-diameter ratio. The results show close agreement between the measured cutting forces and the model predictions.
