CNC machining costs are mainly influenced by material, part complexity, machining time, tolerances, quantity, and tooling. For bulk production, optimizing these factors can significantly reduce the cost per component.
| Cost Factor | Cost Impact | Cost-Saving Approach |
|---|---|---|
| Material | Higher material and machining costs | Select a suitable, readily available grade |
| Part Complexity | More operations and longer machining time | Simplify non-essential features |
| Machining Time | Directly increases machine cost | Optimise design and machining operations |
| Tolerances | Tight tolerances increase machining and inspection requirements | Use only functionally necessary tolerances |
| Setups | Multiple setups increase handling and machine time | Design for fewer setups |
| Tooling | Special tools and fixtures increase setup cost | Use standard tooling where possible |
| Quantity | Low volumes carry higher setup cost per piece | Consolidate into larger production batches |
| Surface Finish | Additional processing increases cost | Specify only the required finish |
Cost-Saving Priorities
For bulk CNC machining, focus first on reducing machining time, simplifying the design, minimising setups, selecting the right material, and increasing production quantity. These factors have the greatest potential to improve the final per-piece cost.
