Saw Cut Loss at 65% saw uptime: a worked example

Suppose saw uptime falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate good cut pieces from pieces per cut cycle, available cut cycles, saw uptime, and the yield left after kerf and cut loss.

The inputs for this scenario

  • Good pieces per saw cut cycle: 4 pieces / cycle (held at the documented default)
  • Available saw cut cycles: 480 cycles (held at the documented default)
  • Saw uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Yield after cut loss: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross pieces capacity = good pieces per cut cycle × available cut cycles.
  • Good pieces capacity works out to 1,211 pieces at these inputs, and this is the headline figure for the scenario.
  • Gross pieces capacity works out to 1,920 pieces at these inputs.
  • Uptime loss works out to 672 pieces at these inputs.
  • Cut loss works out to 37.44 pieces at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where saw uptime sits at 90% and the headline result is 1,676 pieces, this scenario comes in 27.78% below the baseline at 1,211 pieces.
  • It computes good-piece capacity by taking gross capacity and applying saw uptime and post-cut yield, while breaking out uptime loss and cut loss separately. 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.

Results at a glance

  • Good pieces capacity: 1,211 pieces (headline result)
  • Gross pieces capacity: 1,920 pieces
  • Uptime loss: 672 pieces
  • Cut loss: 37.44 pieces
