Fabricated Frame Yield at 99% target first-pass frame yield: a worked example

What does the result look like when target first-pass frame yield reaches 99%? The full calculation is worked below with real intermediate numbers. a fabrication or quality manager needs to measure first-pass quality for welded farm machinery frames

The inputs for this scenario

  • Accepted fabricated frames: 188 frames (unchanged)
  • Total fabricated frames built: 205 frames (unchanged)
  • Target first-pass frame yield: 99 % (raised for this scenario; the documented default is 96)

Working through the calculation

  • Applying the documented formula (Fabricated frame yield = accepted fabricated frames ÷ total fabricated frames built × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 91.71 % frame yield for fabricated frame yield, the number this scenario is built around.
  • At this operating point the engine returns 7.29 percentage points for frame yield gap to target.
  • At this operating point the engine returns 188 frames for accepted fabricated frames.
  • At this operating point the engine returns 205 frames for total fabricated frames built.

How this compares with the baseline

  • Against the tool's baseline example, where target first-pass frame yield sits at 96% and the headline result is 91.71 % frame yield, this scenario lands almost exactly on the baseline at 91.71 % frame yield.
  • A figure at this level is achievable when target first-pass frame yield is genuinely sustained, not just peaked for a shift. It treats every rejected frame equally, so a batch of minor cosmetic rejects and a batch of scrap-grade structural failures produce the same yield number despite very different cost.

Results at a glance

  • Fabricated frame yield: 91.71 % frame yield (headline result)
  • Frame yield gap to target: 7.29 percentage points
  • Accepted fabricated frames: 188 frames
  • Total fabricated frames built: 205 frames
