Abstract: Titanium alloys,due to their high specific strength,excellent heat resistance,and corrosion resistance,are widely used as primary materials in blisks for the aerospace industry. However,the complex geometric shapes,stringent machining precision requirements,and the unique characteristics of titanium alloys present significant challenges during the milling process.These challenges include tool wear,surface quality of the machined parts,and machining efficiency. First,the geometric model of the titanium alloy blisk was established and CNC programming was performed based on the machining features of the blades and flow paths. Subsequently,the milling process for titanium alloy blisks was analyzed,and appropriate tools and machining parameters were selected for experimental validation. Finally,the profiles of the machined blades were measured and analyzed,aiming to provide theoretical guidance and technical support for the efficient and high-quality machining of titanium alloy blisks.

Key words: titanium alloy blisk, optimization of machining parameters, tool wear, profile accuracy
