Abstract:

Aimed at the difficult-to-machine property of titanium alloys, as well as large dimension, complicated construction and large distortion of titanium monolithic component used in large commercial airplanes, research actuality, existing problems and development trends of titanium alloys machining were analyzed. Requirements and the developing trends of titanium tooling techniques such as tool materials, tool structure, and micro edge treating et al were elaborated. Titanium fabrication technologies were discussed which should be reinforced and include type and path of cutting, parameters optimization based on cutting stability, and distortion control and correcting, et al. The relationship between milling parameters and surface integrity was also analyzed. The purpose of this work was to provide a guideline for theoretical research and engineering application.
