Study Notes
What is Manufacturing?
- Manufacturing is derived from the Latin words "manus" meaning hand and "factus" meaning made.
- Manufacturing is the process of converting raw materials into products.
- It involves the use of machines, tools, and labor to produce goods on a larger scale.
Characteristics of Manufacturing
- Manufacturing adds value to materials by changing their shape or properties, or by combining them with other materials.
Types of Manufacturing Processes
- Processing Operations: alter the geometry, properties, or appearance of the starting material
- Assembly Operations: join two or more components to create a new entity
Processing Operations
- Shaping: alter the geometry of the starting material
- Sub-types: Solidification, Particulate Processing, Deformation Processes, Material Removal Processes
- Property Enhancing: improve physical properties without changing shape
- Sub-types: Heat Treatment, Sintering
- Surface Processing: clean, treat, coat, or deposit material on the exterior surface of the work
- Sub-types: Cleaning, Coating & Deposition Process
Assembly Operations
- Permanent Joining: create a permanent joint
- Sub-types: Welding, Brazing & Soldering, Adhesive Bonding
- Mechanical Fastening: fastening by mechanical methods
- Sub-types: Threads, Fasteners, Permanent Fastening
Factors Affecting Manufacturing Process Selection
- Type and nature of the starting material
- Expected quality and properties required
- Technical viability of the process
- Volume of production
- Economy
