Cost per Part — Manual Toolroom (Prototype)
Machined part cost on a manual toolroom (prototype): cycle time × rate + tooling per part + material.
Manual toolroom work bills skilled-labor rates with no automation to amortize — fine for one-offs, ruinous past quantity three. The break-even against CNC arrives the moment programming time is spread over more than a couple of parts.

About Cost per Part — Manual Toolroom (Prototype)
Cost per Part — Manual Toolroom (Prototype) computes the governing relationship C = t·rate/60 + tool/parts_per_edge + material + setup/qty live as you type. Manual toolroom work bills skilled-labor rates with no automation to amortize — fine for one-offs, ruinous past quantity three. The break-even against CNC arrives the moment programming time is spread over more than a couple of parts. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Cost per Part — Manual Toolroom (Prototype)
- 1Enter your values — Cycle time, Machine + labor rate, Tool/consumable cost per edge, Parts per edge/consumable and more (sensible defaults are pre-filled).
- 2Read the live results: Cost per part, Machine-time share, Batch total.
- 3Check the "with your numbers" line to see C = t·rate/60 + tool/parts_per_edge + material + setup/qty substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
