The life and the final failure of the carbide cutting edge in the interrupted cutting when turning steel is ascertained experimentally in this paper, and these results are examined also by comparison with the life and the final failure of the cutting edge in the machining with or without chatters.It is found that : The failures of the cutting edge in this machining differ completely from that in the machining with or without chatters. The cutting edge breaks down along its flank commonly, because the chipping of the cutting edge advance. Accordingly the ISO P20-tcol that has the superior properties for the machining with chatters, suits not always in the interrupted cutting, the H.S.S.-tool has a fair aptitude rather than the P20-tool in this machining.And further, more when chatter vibrations of the tool for this machining occur, the carbide tool face flake off, and, the tool life is short-lived. |
