Abstract

EDM is a non-conventional machining process with feeding material carried out by electric spark (spark) through a gap between the electrode and the workpiece containing liquid in the electric. The usefulness of the liquid is as a medium for rinsing the remnants of erosion material, electrodes and workpieces as electrical conductors. In the manufacturing industry, EDM is widely used for the manufacture of products that demand the quality of surface roughness resulting from smooth cutting and high precision. The Taguchi method is one method in experimental design that can be used to control product quality. This study considers 3 parameters, namely gap voltage, on time, and off time on the SKD-11 material as one of the 13 mm thick dies / dies. This study uses the Taguchi method to obtain optimal parameters with smaller criteria better. Based on the table above the highest voltage parameter gap at level 1 which is 30 volts, the parameters at the most agreed time at level 3 are 120 μs and the most difficult off time parameter to be reached at level 1 is 20 μs to roughness. EDM adalah suatu proses permesinan yang bersifat non konvensional dengan pemakanan material benda kerja yang dilakukan oleh loncatan bunga api listrik (spark) melalui celah antara elektroda dan benda kerja yang berisi cairan di elektrik. Kegunaan cairan tersebut adalah sebagai medium untuk flushing sisa-sisa partikel material hasil erosi,pendinginan elektroda dan benda kerja serta sebagai konduktor listrik. Dalam industri manufaktur, EDM banyak digunakan untuk pembuatan produk-produk yang menuntut kualitas kekasaran permukaan hasil pemotongan yang halus dan kepresisian yang tinggi. Metode Taguchi merupakan salah satu metode dalam desain eksperimen yang dapat digunakan untuk mengendalikan kualitas produk. Penelitian ini mempertimbangkan 3 parameter yaitu gap voltage, on time, dan off time pada pengerjaan material SKD-11 sebagai salah satu bahan pembuatan cetakan/dies dengan tebal 13 mm. Penelitian ini menggunakan metode Taguchi untuk mendapatkan parameter yang optimum dengan kriteria smaller is better. Berdasarkan tabel diatas parameter gap voltage paling berpengaruh pada level 1 yaitu 30 volt, parameter on time paling berpengaruh pada level 3 yaitu 120 µs dan parameter off time paling berpengaruh pada level 1 yaitu 20 µs terhadap kekasaran.

Abstract

At the Sukodono molding company which produces Bioring cone cups using injection molding machines, a trial and error process to obtain parameter setting values on the machine is still applied in the early stages of production. This problem is detrimental to the company because they have to bear the production burden due to production delays. A solution is needed to optimize injection parameters with cycle time response. Therefore, this study proposes an analysis of the application of the Taguchi method by utilizing the signal for noise ratio to determine the influence of factors and also to optimize parameter such as temperature, pressure, and cooling time for the production process. The trial results show that the ideal blend of factors includes injection pressure parameters at level 1 with a value of 80 bar, injection temperature at level 2 in value of 225°C, and cooling time in level one with a value of 0.1 seconds.
