Prediction of GTE vanes deflection by analytical models of technical and geometric initial data in cross line milling on multi-axis CNC machines

In the process of milling profile vanes a gas turbine engine on multi-operational machines, technological scheme transverse line shaping is used. According to this scheme, vane rotates around its own axis, it machined with mill spherical working surface, which performs rotation and interpolated axial movement. The required parameters surface quality airfoil (profile accuracy roughness parameter) are provided by assigning combination controlled processing parameters. However, today there no recommendations calculation assignment combinations for complex-profile surfaces, flow path GTE compressor vanes. For each angle vane, will be determined depending amount deformation, should not exceed tolerance manufacture. course analysis geometric relationships in contact zone curved part dependences were obtained determine magnitude force component during projection Y as well effective diameter mill, necessary calculate total deformation vane. A methodology proposed analytical models determining mode that provide given when developing control program CNC machine.
