Fastener Manufacturing & Thread Rolling worked example
Die Changeover Cost at 110% chargeable setup factor: a worked example in fastener manufacturing & thread rolling
What does the result look like when chargeable setup factor reaches 110%? The full calculation is worked below with real intermediate numbers. Use it when costing header die changes, thread rolling die swaps, pointer tooling changes, or setup-intensive short fastener runs.
The inputs for this scenario
- Die changeover time: 2.5 hr (unchanged)
- Loaded setup or machine rate: 145 $ / hr (unchanged)
- Chargeable setup factor: 110 % (raised for this scenario; the documented default is 100)
- Fixed tooling or approval cost: 90 $ (unchanged)
Working through the calculation
- Applying the documented formula (Die changeover cost = changeover time × loaded rate × chargeable factor + fixed tooling cost) to the inputs above produces each figure below.
- At this operating point the engine returns 489 $ for total die changeover cost, the number this scenario is built around.
- At this operating point the engine returns 196 $ / hr for cost per changeover hour.
- At this operating point the engine returns 399 $ for chargeable setup labor cost.
- At this operating point the engine returns 90 $ for fixed tooling or approval cost.
How this compares with the baseline
- Against the tool's baseline example, where chargeable setup factor sits at 100% and the headline result is 453 $, this scenario comes in 8.01% above the baseline at 489 $.
- A figure at this level is achievable when chargeable setup factor is genuinely sustained, not just peaked for a shift. It models a single clean changeover at a steady rate and does not capture scrap during first-piece tuning, repeated re-trials, or queue time waiting on inspection.
