The prediction of the cutting conditions leading to dynamic instability of a lathe requires knowlege of the vibratory properties of the workpiece or tool and the dynamic characteristics of the cutting process. This paper presents a method to predict the dynamic characteristics of the cutting process from the static cutting tests. Steady-state cutting tests are carried out and dynamic characteristic values as a function of cutting speed and feed rate are calculated. After some consideration of the dynamic cutting values and their components, it is revealed that the uncut surface slope variation with the vibratory workpiece influences the dynamic cutting process.
