Abstract:The structure of Titanium alloy blisk is complex and the material is difficulttocut，which brings great difficulties to the manufacture.Applying the milling technology to the manufacture of blisk can solve the above problems effectively.The optimization of process parameters is great significance to the advantage of milling process.The influence of process parameters on cutting force is studied by means of the plunge milling experiment of titanium alloy.According to the experimental data，the cutting force prediction model is established and tested.Taken the cutting force and metal removal rate as the goal，the process parameters are optimized based on MATLAB to provide theoretical reference and technical support for Titanium alloy blisk highefficiency machining.
