Ammunition Component Capacity Gap Calculator at 62% press and tooling uptime: a worked example

Suppose press and tooling uptime falls to 62%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate usable component production capacity from output per cycle, cycles available, uptime, and accepted yield for demand comparison.

The inputs for this scenario

  • Cases or bullets formed per press cycle: 8,500 units/cycle (held at the documented default)
  • Scheduled press cycles in the period: 20 cycles (held at the documented default)
  • Press and tooling uptime: 62 % (the input this scenario stresses; the baseline uses 86)
  • First-pass accepted yield: 95 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross component capacity = output per production cycle × available production cycles.
  • Usable accepted component capacity works out to 100,130 accepted units at these inputs, and this is the headline figure for the scenario.
  • Gross component production capacity works out to 170,000 units at these inputs.
  • Capacity lost to downtime works out to 64,600 units at these inputs.
  • Component capacity lost to rejects or holds works out to 5,270 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where press and tooling uptime sits at 86% and the headline result is 138,890 accepted units, this scenario comes in 27.91% below the baseline at 100,130 accepted units.
  • It computes usable accepted component capacity by discounting gross press output for equipment uptime and first-pass yield, and splits the loss into downtime and reject buckets. 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

  • Usable accepted component capacity: 100,130 accepted units (headline result)
  • Gross component production capacity: 170,000 units
  • Capacity lost to downtime: 64,600 units
  • Component capacity lost to rejects or holds: 5,270 units
