The Performance and Cutting Parameters Optimization in Milling of Nickel Base Superalloy FGH97

Abstract

The powder preparation, material properties, the cutting characteristics and parameter selection for a nickel base superalloy FGH97 are summarized in this paper. It introduces the influence of various elements on the properties of the alloy, the ideal tool materials is coated cemented carbide tool and PCBN ceramic cutting tool. Generally we can choose the rake angle of 0°~10°, clearance angle of 6°~12°, cutting edge angle of 30°~60°, distortion angle of 0.5°~3°, tool cutting edge inclination angle of-10°~-20°. The optimal parameters for machining superalloy is axial cutting depth (range from 0.15~0.20mm), radial cutting depth (range from 10~20mm), the cutting speed (range from 40~60m/min), feed per tooth (range from 0.08~0.10mm/z).
