The normal force applied through a tool divided by the effective contact area at the glass surface.

Meaning and boundaries
Operator effort or tool weight alone is not pressure, and the effective area changes with pad compliance, tilt, wear, surface shape, and motion.
Why it matters in glass restoration
Pressure influences removal rate, heat, scratch morphology, pad deformation, vibration, and edge transition.
