Glass Cutting Yield at 68% target cutting yield: a worked example

Suppose target cutting yield falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate cutting yield for float glass, laminated glass, mirrors, or architectural glass lites.

The inputs for this scenario

  • Saleable cut glass area or lites: 850 sq ft or lites (held at the documented default)
  • Glass sheet area or lites loaded to cutting: 1,000 sq ft or lites (held at the documented default)
  • Target cutting yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Glass Cutting Yield = saleable cut glass area or lites ÷ glass sheet area or lites loaded to cutting × 100.
  • Glass Cutting Yield works out to 85 % cutting yield at these inputs, and this is the headline figure for the scenario.
  • Glass Cutting Yield gap to target works out to -17 points at these inputs.
  • Saleable cut glass area or lites works out to 850 count at these inputs.
  • Glass sheet area or lites loaded to cutting works out to 1,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target cutting yield sits at 95% and the headline result is 85 % cutting yield, this scenario lands almost exactly on the baseline at 85 % cutting yield.
  • It computes the percentage of glass area or lites loaded to the cutting line that becomes saleable cut glass, plus the gap to your target yield. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
