Manufacturing Processes and Classification
The chapter provides a comprehensive overview of various manufacturing processes, categorizing them into additive, subtractive, and shaping/forming methods. It discusses the advantages and limitations of each type, particularly focusing on aspects such as material efficiency, production speed, and part design considerations. Furthermore, it emphasizes the importance of selecting the appropriate manufacturing process based on part complexity, material type, and cost-efficiency to enhance product quality and manufacturability.

What we have learnt
- There are three main types of manufacturing processes: additive, subtractive, and shaping/forming.
- Each manufacturing process has specific advantages and limitations regarding complexity, precision, material efficiency, and cost.
- The choice of manufacturing process significantly impacts product quality, production speed, and overall costs.
Key Concepts
- -- Additive Manufacturing
- A process that builds objects by adding material layer by layer, commonly known as 3D printing, using methods like FDM and SLA.
- -- Subtractive Manufacturing
- Processes that create parts by removing material from a solid workpiece through methods such as CNC machining and laser cutting.
- -- Shaping/Forming Processes
- Manufacturing techniques that change the shape of materials without adding or removing material, including casting and forging.
- -- Part Design for Manufacturability (DFM)
- Guidelines for designing parts in a manner that enhances manufacturability, considering material compatibility, geometric simplicity, and assembly efficiency.
- -- Process Selection Criteria
- Factors that influence the choice of manufacturing process, including material type, complexity, volume of production, tolerances, and cost.
