End-Of-Life Tooling Reserve at 65% expected machine uptime: a worked example

Suppose expected machine 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 end-of-life tooling reserve for tooling, fixtures, dies and mold economics using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

Good parts produced per press cycle: 4 units / cycle (held at the documented default)
Remaining tool life in cycles: 480 cycles (held at the documented default)
Expected machine uptime: 65 % (the input this scenario stresses; the baseline uses 90)
Expected first-pass yield: 97 % (held at the documented default)

Working through the calculation

The calculation starts from the formula this tool documents: Gross end-of-life tooling reserve capacity = end-of-life tooling reserve output per cycle × available end-of-life tooling reserve cycles.
Good end-of-life tooling reserve capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
Gross end-of-life tooling reserve capacity works out to 1,920 units at these inputs.
End-of-life tooling reserve downtime loss works out to 672 units at these inputs.
End-of-life tooling reserve yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

Against the tool's baseline example, where expected machine uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
It calculates the good-part capacity remaining in a tool by discounting gross cycle capacity for uptime and first-pass 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.
