During the milling process of titanium alloy thin-walled parts

the cutter angle has a significant influence on the workpiece deformation

milling force and milling vibration. Extend the service life of cutting tools and reduce tool wear

milling process simulation model of Ti6Al4V titanium alloy thin-walled pieces is established by using ABAQUS software

with the milling force and milling temperature as evaluation index

using the single factor and orthogonal method to analyze the effects of cutting tool rake angle

relief angle and helix angle on the milling force and milling temperature

and the milling force experiment is carried out to verify the simulation results. The simulation results show that with the increase of the rake angle

the milling force decreases and the milling temperature fluctuates. With the increase of the relief angle

the milling force decreases

and the milling temperature decreases first and then increases. With the increase of helix angle

the maximum axial force increases

the maximum tangential force slowly decreases

the maximum radial force has no obvious variation

and milling temperature decreases first and then increases. Through orthogonal test and range analysis

the order of primary and secondary influence degree of different factors on indexes and the optimal level combination of factors are defined.
