Make a 0/1 column defect (1 = defective). Use the inputs temperature_c, vibration_mm_s, pressure_bar and rpm, and split with train_test_split (test_size=0.25, random_state=42, stratify on defect).
Train the RBF pipeline (C=1, gamma="scale") using only temperature_c and vibration_mm_s from the same split. Store the test accuracy, rounded to 3 decimals, in result. Extra columns that carry no signal add noise to the distances.
