摘要：The paper presents analysis of vibration modes of a high-frequency assisted turning tool. The analysis was performed with different locations of contact areas positions. Turning tool contact area set was found in which tool modes overlap or localize. Also it was conducted periodic turning tool response analysis to periodic impact. The analysis was caried out with three diferent contact area sets and it was concluded that when using fifth conctact area set longitudinal turning tool modes are dominant and the frequency amplitude is the biggest.
