Abstract
Micro-ultrasonic-machining(micro-USM) and micro electrical discharge machining(micro-EDM) were jointly used to resolve the critical problems of micro Laval-nozzle machining techniques of microcrystalline-mica-ceramic(MCMC),including a special machine with high precisions and multiple functions,the preparation of micro-USM tools,the clamping and locating of workpieces,the design of micro-USM process and the selection of the micro-USM conditions.Though a self-developed high-precision multi-functional machine tool,micro-USM was adopted to machine micro Laval-nozzles of MCMC cooperated with micro-EDM for tools preparation.Workpiece holding devices were designed to keep the repeat positioning accuracy less than 2 μm.Furthermore,by comparing two machining processes,a Laval-nozzle was successfully made by the better machining process with an inlet diameter of 360 μm,outlet diameter of 320 μm,throat diameter of 170 μm and total length of 550 μm.

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
