Machining and Inspecting Technology of Circumferential Hammer foot for Heavy Duty Gas Turbine Blade
The circumferential hammer foot for heavy duty gas turbine blade has the characteristics of large radial plane of basin back,large diameter and complex transition arc surface,complex design reference and position correlation di-mension,which result in the difficulty of integrated milling of this type of blade tenon and poor repeatability of CMM meas-ure.In this study,through technological innovation and breakthrough of technical bottleneck,the horizontal and integrated milling technology of circumferential hammer foot and its CMM measure technology are developed,which meet the surface quality,dimensional accuracy,machining efficiency and appearance requirements of circumferential hammer foot tenon.
