APPLICATION OF SUPERABSORBENT COOLANT AS A NOVEL APPROACH TO SEMI-DRY MACHINING
Bibliographic record
Abstract
Cutting fluids play a significant role in manufacturing processes. Machining certain materials is impossible without them. Due to high temperature and friction during cutting operations, proper cooling and lubrication are necessary to improve the efficiency, quality of the final workpiece and to reduce tool failure costs. This study presents a novel coolant suitable for different machining processes. The focus of this work is the application of a superabsorbent coolant (SAC) during hardened H13 steel machining, Inconel 718 turning, and aluminium silicon alloy tapping and drilling with an uncoated carbide tool. Hence, different machining operations have been attempted to better understand the range of function for SAC. Moreover, the possibility of superabsorbent material use as a coolant has been evaluated in comparison with dry and flood conditions. The use of SAC is a novel method of semi-dry machining that demonstrates the advantages of hydrogels as a coolant and opens a new window for industrial applications. SAC is a superabsorbent polymer enriched by a nanofluid and injected near the cutting zone. Its main purpose, besides improving machining performance, is to safely provide beneficial properties of nanoparticles (higher thermal conductivity and lubricity) and to prevent their distribution in air, which along with other chemical additives, can cause serious occupational and environmental hazards. The results of machining studies indicate that SAC can considerably reduce the friction conditions in the cutting zone, greatly reducing cutting force, while improving surface integrity and enhancing tool life. In addition, the friction conditions at the cutting zone have been improved. Ultimately, chip undersurface roughness was measured to ensure the penetration of the nanoparticles into the cutting region and to reduce friction between the tool and chip. The results show a lower surface roughness of the chip surface.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
