Electron beam melting (EBM) has been found to be a promising technology for producing complex shaped parts from gamma titaniumaluminide alloys (γ-TiAl). The parts produced by this process are projected to have dimensions very close to the desired final shapes. However, the surface roughness of the parts produced by EBM is excessively rough. In many applications, it is necessary to improve thequality of manufactured parts using a convenient post process. This paper determines process parameters of end milling when it is usedas a post process for the parts produced by EBM. Design of experiments has been used to study the effect of the selected input parametersof end milling (spindle speed, feed rate, depth of cut and coolant type) on the surface roughness of γ-TiAl parts. Response surface methodologyis used to develop a predictive model for surface roughness. Effects of the selected milling process are investigated. This paperalso optimizes the selected process parameters to minimize the value of the obtained surface roughness.
