Tooling, Fixtures, Dies & Mold Economics worked example

Tooling Amortization at 99% machine uptime during the run: a worked example in tooling, fixtures, dies & mold economics

This scenario runs the tooling amortization calculation on the strong side: 99% machine uptime during the run, with every other input held at its documented default. Use it when tooling amortization in tooling, fixtures, dies and mold economics is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Parts produced per tooling cycle: 4 units / cycle (unchanged)
  • Tooling cycles available in the run: 480 cycles (unchanged)
  • Machine uptime during the run: 99 % (raised for this scenario; the documented default is 90)
  • First-pass yield off the tool: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross tooling amortization capacity = tooling amortization output per cycle × available tooling amortization cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good tooling amortization capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross tooling amortization capacity.
  • At this operating point the engine returns 19.2 units for tooling amortization downtime loss.
  • At this operating point the engine returns 57.02 units for tooling amortization yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where machine uptime during the run sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • Use it when setting the amortization base for a new tool, sizing a program's committed volume, or checking whether a run will hit its good-part target. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Good tooling amortization capacity: 1,844 units (headline result)
