New identification and evaluation techniques for machining systems lead to an increase in the efficiency of a production system. This paper presents relationship between tool life, design features, fatigue strength and parameters of vibrations. To cope with this objective, vibration influence on tool wear is assessed, which considers the phase shift of vibration in different coordinates and forces on rake and rear faces of the tool. Tool life is predicted based on fatigue strength of tool material and parameters of tool vibrations. Static and dynamic characteristics of cutting tools during different machining conditions are analyzed using different cutting tools. Test results of cutting tools with different clamping types during static, dynamic and cutting processes, together with the simulation results suggest a relationship between the characteristics of the tool, the elastic system vibrations and tool life.
