Forging vs Casting vs CNC Machining – Comparison Table | |||
Aspect | Forging | Casting | CNC Machining |
Strength | ***** Excellent grain flow, highest mechanical strength | ** May contain internal defects like porosity | **** Good, but grain structure not optimized |
Precision | *** Moderate; better in closed-die forging | ** Low to moderate, depends on process | ***** High precision, tight tolerances |
Surface Finish | ** Requires post-machining or polishing | *** Better in die/investment casting | ***** Excellent, depending on tooling and settings |
Material Utilization | **** Less waste than machining | *** Moderate, some gating/risers lost | ** Higher waste due to cutting/removal |
Tooling Cost | **** Moderate to high (dies required) | *** Low for sand casting, high for die casting | ** Low, mainly tooling and fixturing |
Production Volume | **** Medium to high volumes | **** Suitable for both small and large batches | ** Best for low to medium volume, or prototyping |
