Powder-mixed electrical discharge machining (PMEDM) research is recently getting popular. The lack of suitable vise for the experiment limits the real investigation using this method. Therefore, this paper aims at creating a suitable vise to be used in PMEDM studies to optimize the electrical discharge machining (EDM) process parameters by including an electrically conductor metal powder in the dielectric fluid. In comparison with other machining methods, the expense of using EDM is greater due to the longer processing durations involved. It has been theorized that PMEDM can increase the effectiveness of EDM. PMEDM has the potential to enhance the surface smoothness of machined products, boost MRR, and reduce the tool wear (TWR). The development process of the vise includes the design using a 3D design software, design selection, machining, and measuring. Outcome from this paper shows that a new vise was developed to suit the PMEDM experiment works. For the future works, study on the powder concentration and gap voltage in SiC PMEDM is suggested. To decide how many tests need to be performed, a Taguchi orthogonal array with three levels and two factors can be utilized. The results of this study are expected to lead on the improvements in surface smoothness, TWR, machining time, and machining costs.

摘要

Powder-mixed electrical discharge machining (PMEDM) research is recently getting popular. The lack of suitable vise for the experiment limits the real investigation using this method. Therefore, this paper aims at creating a suitable vise to be used in PMEDM studies to optimize the electrical discharge machining (EDM) process parameters by including an electrically conductor metal powder in the dielectric fluid. In comparison with other machining methods, the expense of using EDM is greater due to the longer processing durations involved. It has been theorized that PMEDM can increase the effectiveness of EDM. PMEDM has the potential to enhance the surface smoothness of machined products, boost MRR, and reduce the tool wear (TWR). The development process of the vise includes the design using a 3D design software, design selection, machining, and measuring. Outcome from this paper shows that a new vise was developed to suit the PMEDM experiment works. For the future works, study on the powder concentration and gap voltage in SiC PMEDM is suggested. To decide how many tests need to be performed, a Taguchi orthogonal array with three levels and two factors can be utilized. The results of this study are expected to lead on the improvements in surface smoothness, TWR, machining time, and machining costs.
