A Study of the Sensitivity of Parameters Affecting Surface Roughness in High Speed Milling Superalloy GH4169

Abstract:

The orthogonal experiment is processed for high-speed milling superalloy GH4169 with TiAlN coated carbide inserts. The empirical formula of the surface roughness is acquired by using Genetic Algorithm method. On the basis of this formula, studying the absolute sensitivity and relative sensitivity of surface roughness for milling speed, depth of cut and feed; The results showed that in the process of high-speed milling of high-temperature alloy GH4169, Surface roughness is most sensitive to the change of milling feed; change of milling depth take second place and milling speed is the least sensitive.
