Abstract

GH4169 high-temperature alloy is a difficult-to-machine material commonly used in the aerospace industry. The surface roughness and material removal rate are important indicators in the production of WEDM processing GH4169 high-temperature alloy, and the discharge parameters directly affect the surface roughness and material removal rate. Several groups of optimized discharge parameters were used to process GH4169 high temperature alloy, and the specific influence of each discharge parameter on the surface roughness and material removal rate was obtained respectively. The results of the study provide a technical reference for the production of WEDM processing GH4169 high-temperature alloy, and a suitable combination of discharge parameters can be selected according to different production requirements.
