Subtractive Manufacturing: Understanding the Process and Comparison with Additive Manufacturing
Subtractive manufacturing is a traditional fabrication method that removes material from a solid block to create a final part. This process is widely used in industries requiring high precision and durability, such as aerospace, automotive, and industrial manufacturing. But how does it compare to additive manufacturing? Let’s explore the key differences and advantages of each approach.
What is Subtractive Manufacturing?
Subtractive manufacturing involves cutting, drilling, milling, or turning a solid material to achieve the desired shape. Common techniques include:
- CNC Machining – Uses computer-controlled tools for high precision.
- Milling – Rotating cutting tools remove material from the workpiece.
- Turning – The workpiece rotates while stationary tools remove material.
- Laser Cutting – A high-energy laser cuts through materials like metal and plastic.
Benefits of Subtractive Manufacturing
- High Precision: Ideal for intricate designs with tight tolerances.
- Material Variety: Works with metals, plastics, wood, and composites.
- Surface Finish: Provides superior finishes compared to many additive processes.
- Scalability: Suitable for both prototyping and mass production.
