Abstract
Product quality depends on the surface quality of the machined part and machining performance relay on the production rate of the process. Whereas surface quality of a part is based on surface roughness (SR) and production rate depend on the material removal rate (MRR). Minimum surface roughness and maximum MRR are of great value in the field of manufacturing. In powder mix Electrical Discharge Machined (EDM) selection of input parameters and their ranges are of great value because its helps to achieve the optimize values of the SR and MRR. This study contains the effect of four input variables; pulse on time (Pon), discharge current (DC), pulse off time (Poff) and powder concentration of EDM on SR and MRR of Inconel 718. Response Surface Methodology (RSM) center composite design (CCD) and Analysis of Variance (ANOVA) are used with 5% significant coefficient. It was observed that DC significantly affects the SR and MRR followed by the Pon.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
