Glass Cut Yield at 99% target glass cut yield: a worked example

This scenario runs the glass cut yield calculation on the strong side: 99% target glass cut yield, with every other input held at its documented default. tracking glass room yield before IGU assembly or glazing

The inputs for this scenario

  • Good glass lites or usable cut area: 1,830 lites (unchanged)
  • Total glass lites or issued cut area: 1,980 lites (unchanged)
  • Target glass cut yield: 99 % (raised for this scenario; the documented default is 94)

Working through the calculation

  • Applying the documented formula (Glass cut yield = good glass lites or usable cut area ÷ total glass lites or issued cut area × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 92.42 % for glass cut yield, the number this scenario is built around.
  • At this operating point the engine returns 6.58 points for glass cut yield gap to target.
  • At this operating point the engine returns 1,830 count for good glass lites or usable cut area.
  • At this operating point the engine returns 1,980 count for total glass lites or issued cut area.

How this compares with the baseline

  • Against the tool's baseline example, where target glass cut yield sits at 94% and the headline result is 92.42 %, this scenario lands almost exactly on the baseline at 92.42 %.
  • Use it at shift end or per glass batch to grade cutting-table performance, validate optimizer nesting changes, or benchmark a new glass supplier's stock-sheet quality. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • glass cut yield: 92.42 % (headline result)
  • glass cut yield gap to target: 6.58 points
  • good glass lites or usable cut area: 1,830 count
  • total glass lites or issued cut area: 1,980 count
