Abstract

fetched live from OpenAlex

Accurate measurements of cutting forces are critical in machining operations for maximizing production, detecting tool wear and failure, adaptive control and monitoring. Traditionally, cutting forces are measured using piezoelectric quartz force sensors or strain gauges. These types of sensors have limitations in that they are unable to measure static force signals. The quartz crystals of a piezoelectric force sensor generate an electric charge only when force is applied to or removed from them. Strain gauges suffer drifts over a long period time. In order to overcome the challenges, a novel table dynamometer is developed based upon laser optics to measure planar forces and moments in both the static and dynamic range. The developed table dynamometer allows the measurement of both the in plane linear movements and the in-plane rotations. In order to achieve high sensitivity, a monolithic, flexure-based mechanical amplifier is adopted into the proposed table dynamometer. A prototype of the developed system is fabricated and the sensitivity and frequency bandwidth of the system are experimentally investigated. The results showed good agreement between the optical force sensor and a reference force transducer. The proposed dynamometer is tested for use in the measurement of cutting forces and compared with a conventional piezoelectric dynamometer.

Teacher imitation

Not 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.
