Representative CNC machine shop scenario
Escenario representativo — exposición modelada, no un resultado verificado de cliente.
Problema
A job shop prices spindle time and material but leaves programming, setup, and expected downtime out of the quick quote — the bid looks healthy until hidden machine minutes erode margin.
Conjunto de entradas
- Machine rate $92/h, planned run 14 h, expected downtime 2.1 h
- Material $680, tooling wear $95, scrap allowance 4%
- Target margin 20%
Pérdida oculta
Setup/programming minutes and non-productive downtime are not loaded into the customer-facing quote — roughly $290–$340 per job in this illustrative input set.
Setup, programming & downtime leak
Resultado del cálculo
Modeled loaded job cost ~$2,180 vs a $1,920 quote — about a 12-point gap versus the 20% target margin floor (representative model output only).
Direct machine and material cost loaded with downtime, scrap, and tooling buffers; minimum safe price computed at the entered target margin.
Acción sugerida
Reprice or tighten scope if the customer offer sits below the modeled safe floor before accepting the lot.
Impacto estimado: Illustrative per-job margin pressure in the modeled band above — not a measured client outcome.
Nota metodológica
SectorCalc's governed premium engine applies deterministic inputs → formula pipeline → threshold read. This scenario uses synthetic numbers to show decision structure only.
- Machine rate includes operator burden as entered
- Scrap and downtime hours are user estimates
- Representative scenario — modeled exposure, not a verified customer outcome.
