Magnesium alloys have been widely used in biodegradable applications due to their propensity for corroding within the human body and their initial mechanical properties. However, recent research has shown that the increased rate of magnesium deterioration inside the human body causes structural stability of the implant to be disturbed and lost quickly. Electrical discharge machining (EDM) die sinking is a machining technique used to produce complex forms with high tolerance in magnesium alloy, focusing on the relationship between process parameters and machining effect. The research aims to investigate the effect of EDM process parameters on surface roughness, material removal rate (MRR), and energy consumption to optimize and validate the machining parameter prone to energy saving and the best machining characteristic. The experiments were optimized using a design of experiment approach with a full factorial design and response surface methodology. The relationship models b.....
