Abstract

The paper presents an original method for stability analysis of the main spindle variations in transversal direction at CNC lathe, which by means of the Mihailov criterion and adequate software packages, establishes the dynamic instability character due to the specific processing conditions and to the grinding regime parameters. This creates the premises for rational design of the turning process, as well as for the structural design of the turning tool.
