Investigation of Micro-EDM Input Parameters on Various Outputs in Machining Ni-Ti Shape Memory Alloy Using Full Factorial Design

Abstract:

Micro Electric Discharge Machining (μ-EDM) is a non-traditional machining process which is used for drilling micro holes in a high strength-to-weight ratio advanced engineering materials like shape memory alloys that have many applications in the field of aerospace and medical sciences. However, in order to achieve the desired output responses the process control parameters of the machine have to be set at an optimal setting. In this research work, an investigation has been made to study the influence of the input parameters (such as capacitance, discharge voltage and electrode material) on the micro-EDM process output responses (such as MRR, TWR, Ra and circularity of the micro-holes) while drilling the micro-holes on Ni-Ti shape memory alloy. The full factorial design based study resulted in a set of recommended values for input variables to obtain the desired output. Mathematical predictive models have also been developed, which predict good values for the output responses.
