| Material |
- Material Type: Different materials have varying costs and machinability.
- Material Grade: Higher-grade materials or specialty alloys cost more.
- Material Wastage: Larger raw material blocks result in higher wastage and costs.
|
| Design Complexity |
- Geometry: Complex shapes and intricate features require more time and advanced setups.
- Tolerances: Tighter tolerances require slower speeds and more quality checks.
- Surface Finish: High-quality finishes need additional passes or post-processing.
|
| Volume |
- Batch Size: Smaller batches have higher per-unit costs due to setup overhead.
- Economies of Scale: Larger runs reduce per-part costs by spreading fixed expenses.
|
| Tooling and Setup |
- Custom Tools: Custom cutting tools or jigs increase upfront costs.
- Setup Time: Longer setup times for complex parts add to costs.
- Machine Type: Advanced multi-axis machines are more expensive to operate.
|
| Post-Processing |
- Secondary Operations: Processes like anodizing, polishing, and heat treatment add expense.
- Inspection and Testing: Advanced quality checks, such as CMM inspections, require time and resources.
