The workpiece parameter is based on λ·θ·ρ theory, which is the thermal conductivity (λ), melting point (θ) and electrical resistivity (ρ). So, it is numerical.
Actually this is my first time using DOE.

My title is on the Optimatization of micro EDM. I need to design experiment with 4 factors which is voltage, capacitance, machining speed and the workpiece. Each factor consists 5 levels. If I were to use full factorial, I gonna run 1024 experiments, which is quite impossible due to time constraint. I can only run about 60 experiments. So what…[Read more]
