Meaning and boundaries
A single recommended RPM or temperature is not a process window; pressure, speed, dwell, motion, fluid, pad condition, tool size, glass type, environment, and uncertainty interact.
Why it matters in glass restoration
It converts craft knowledge into trainable limits, warnings, stop-work triggers, and validation experiments.
