Manufacturing of blades in air turbine motors according to complicated shape and critical working conditions needs a high technology. The root of blade under applied forces should have high surface quality and dimensional accuracy in comparison with the other blade components. In this study, the surface quality due to different types of available wire-cut machines for machining of compressor blade root has been investigated. To this end some samples has been machined by different wire-cut machines. Afterwards the different components of surface integrity (such as surface roughness, surface topography, hardness, thickness of affected surface layers, microcrackes and pits, residual stresses) has been studied. Finally, the machining of the root of compressor blade with this process has been discussed and concluded.
