Key cost factors include:
- Part Complexity: Intricate designs (e.g., tight tolerances, multiple tool changes) require more programming time and machine runtime.
- Material Type: Expensive metals (e.g., titanium) or hard-to-machine alloys increase raw material and tooling costs.
- Batch Size: Small batches have higher per-unit costs (due to setup/programming time), while large batches benefit from economies of scale.
- Finish Requirements: Post-fabrication processes (e.g., polishing, coating) add labor and material expenses.
