摘要
Wire electric discharge machining (WEDM) is a nonconventional machining method to cut hard and conductive material with the help of a moving electrode. High-strength low-alloy steel (HSLA) is a hard alloy with high hardness and wear-resisting property. The purpose of this study is to investigate the effect of parameters on cutting speed and dimensional deviation for WEDM using HSLA as workpiece. It is seen that the most prominent factor for cutting speed and dimensional deviation is pulse-on time, while two-factor interactions play an important role in this analysis. Response surface methodology was used to optimize the process parameter for cutting speed and dimensional deviation. The central composite rotatable design was used to conduct the experiments. The analysis of variance was used for the investigation of significant factors.
