| Popis: | Electric discharge machining (EDM) is a non-conventional machining use thermal energy from overheated electron source to remove small portion of material. EDM process has an advantage on high geometric complexity and micro leveling of dimensioning. The present of thermal energy to eliminate the unwanted material in EDM are highly depending on heat affected zone. This can contribute to decreasing of the product quality with surface roughness and micro crack existing after machining. Magnesium alloys (AZ31B) material has the special characteristic to explore the heat distribution effect on the heated surface. Finite element analysis with heat flux Gaussian boundary condition is applied to understand the governing equation of the heat behavior. At the same time, finding the size of spark created on the AZ31B gap is studied. The ANSYS software applied to simulate the heat distributes on the AZ31B surface. The simulation of ANSYS indicates potential zone of material removal through heat distribution. The simulation is compare to the actual experimental of μEDM and finds the similarities. The heat distribution on AZ31B with different size of spark shows a good agreement between simulation and experimental results. |
