Software still needs to calculate the duty cycle percentage based on the frequency. And set timer A reload to the measured value in timer B. Webb12 mars 2024 · It was found that MRR and EN increase with the increase in IP and Ton and decrease with the rise in Toff time. The values of optimum process parameters found at impulse current (15 A), pulse on time (490 µs) and pulse off count (6) were MRR (366 mg/min), enlargement in diameter (229 µm) and circularity (0.014 µm).
