Abstract
Usually the mechanical components are jointed by thread or welding. The thread is preferred in situations that require disassembly of the set. In pipes subjected to high temperature and pressure the stainless steel is typically used and connection per thread is employed. The objective of this work is to analyze the influence of the temperature on the tool life in t turning of the external thread by the radial infeed method in the 304L austenitic stainless steel. The experiments were carried out in a CNC lathe and the temperature during the operation was measured by a thermographic camera. The tool wear was evaluated using a scanning electron microscope (MEV). The results showed a direct influence of temperature on the tool life and adhesion of workpiece material on the tool.
