Alternatives To Traditional Machining __hot__ -

| Feature | Traditional Machining | Non-Traditional Machining | | :--- | :--- | :--- | | | Direct physical contact | No direct physical contact (mostly) | | Cutting Mechanism | Shear deformation (chip formation) | Melting, vaporization, dissolution, erosion | | Tool Hardness | Tool must be harder than workpiece | Tool hardness is irrelevant (e.g., laser, EDM) | | Surface Integrity | May leave residual stress | May create a Heat Affected Zone (HAZ) or chemical residue | | Material Waste | Significant chips/scrap | Material is often turned into dust/dissolved (harder to recycle) | | Speed | Generally faster for standard parts | Generally slower, used for difficult applications | | Capital Cost | Lower to Moderate | High (specialized equipment required) |

Alternative machining processes are generally categorized by the type of energy used to remove material. alternatives to traditional machining

She walked across the lab to the new wing—the one the old-timers called “the kitchen” because it smelled of polymers and light. Her boss, a kid named Jensen with a 3D printer on his desk, looked up. Marta shook her head

Marta shook her head. “I’m a pragmatist. The old machines have their place—for roughing, for big blocks of steel. But this?” She tapped the heat exchanger. “This is what we should have been doing all along.” But this
