A common method of turbine disk’s fir tree slot machining is broaching. Due to the high costs of tools and broaching machines, long time of tools designing and manufacturing and necessity to resharpening and recoatings, alternative methods of fir tree slots machining in turbine disks are still being researched [1–4]. One of those methods is wire electrodischarge machining WEDM. Its application in production of responsible machine parts is currently the subject of many research works. This method allows a significant reduction in production costs and increase production flexibility due to the use of a universal tool, such as thin wire, and simple machine programming [2–5]. The accuracy of the WEDM machining depends largely on the vibrations and deflection of the electrode caused by the forces accompanying the erosion process. The reduction of the forces impact on the shape accuracy can be obtained in additional, finishing passes of wire electrodes [2, 6–8]. The purpose of this research was to determine the effect of electrode infeed on shape accuracy and surface roughness in finishing fir tree slot machining made of Inconel 718 alloy.
