Study Notes
Production Technology - Introduction
- The course covers introduction to production technology, joining processes and welding, casting and pattern making, machining processes, material classification and testing, metal forming processes, and measurement and measurement tools.
- The evaluation will include attendance (5 marks), participation (5 marks), midterm assessment (40 marks, including workshop (15 marks), quiz (5 marks), and written (20 marks)), and final-term examination (50%). The total marks are 100.
- Key introductory topics include defining manufacturing processes, classifying manufacturing processes, factors for production process selection, and industrial/workshop safety.
- Manufacturing processes involve altering the geometry, properties, or appearance of a material to create a product.
- This is achieved using various physical and chemical processes, tooling, machinery, power, and labor, potentially resulting in waste.
- Manufacturing enhances material value through shaping and combining it with other materials or altering its properties, using processing and assembly operations.
- Materials in manufacturing can be classified into metals, ceramics, polymers, and composites. A combination of these categories can also exist. For example, metal-ceramic composites.
What is Manufacturing Process?
- Manufacturing is the application of physical and chemical processes to change the geometry, properties, and appearance of a starting material to produce parts or products.
- Machinery, tooling, power, and labor are involved in the process.
- Manufacturing additions value to raw materials or components into finished products. Raw or starting materials are transformed into processed parts, with some parts becoming scraps or waste.
Classifications of Manufacturing Processes
- Two basic categories include processing and assembly operations.
- Processing operations alter the shape, properties, or appearance of a material (e.g., shaping, property enhancing, surface processing).
- Assembly operations combine components to create a product (e.g., joining and mechanical assembly).
- Shaping processes alter the geometry of a workpiece.
- Property-enhancing processes modify physical characteristics of a workpiece.
- Surface processing operations modify the material's surface (e.g., cleaning, treatments, coating).
- Specific examples of each category include casting, powder metallurgy, rolling/ forging, turning, heat treatment, and sand blasting.
Factors for Selecting a Production Process
- Shape and size of product
- Production quantity
- Type of material
- Surface finish and dimensional accuracy
- Quality and property requirements
- Cost of the product
