Study Notes
Production Technology - Introduction
- Course covers introductory topics in production technology
- Topics include: 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.
- Evaluation includes attendance (5 marks), participation (5 marks), midterm assessment (40 marks, including workshop 15, quiz 5, written 20), final-term examination (50%) for a total of 100 marks.
Manufacturing Process
- Application of physical and chemical processes to change the geometry, properties, or appearance of a starting material to create parts or products.
- Inputs include starting material, machinery, tooling, power, and labor.
- Outputs include processed part and scrap/waste.
- Manufacturing adds value to the material by changing its shape or properties, or by combining it with other materials through processing and/or assembly operations.
Materials in Manufacturing
- Most engineering materials can be classified into four basic categories: metals, ceramics, polymers, and composites.
- These categories can combine to form metal-ceramic composites, metal-polymer composites, and ceramic-polymer composites.
Classification of Manufacturing Processes
-
Two basic types: processing operations and assembly operations
-
Processing operations alter the work material's geometry, properties, or appearance.
-
Assembly operations join two or more components to create a new product.
-
Processing operations are further categorized into:
- Shaping processes (solidification, particulate, deformation, material removal)
- Property-enhancing processes (heat treatment, cleaning and surface treatments, coating and deposition processes)
- Surface processing operations (cleaning, surface treatments, coating and thin film deposition)
-
Assembly operations include joining and mechanical assembly.
Factors to Consider in Selecting a Production Process
- Shape and size of the product
- Quantity to be produced
- Type of materials used
- Surface finish and dimensional accuracy
- Quality and property requirements
- Cost of the product
Industrial Safety
- Industrial safety is primarily a management activity
- , it is concerned with:
- Reducing hazards
- Controlling hazards
- Eliminating hazards from industries and industrial units.
- Industrial safety is important because it reduces costs associated with employee injuries, including compensation, medical aid, training new employees, lost time from work, investigation expenses, supervision and inspection costs, damage to materials, machinery, and wages payable during injuries, and loss of morale
Safety in a Workshop
-
Working safely is crucial for both workers and machines/equipment. Safe practices should be learned first in order to work correctly, efficiently, and prevent injury or damage.
-
Safety should include both personal preparation, housekeeping, safe work practices, and fire prevention.
-
Personal preparation: Wear appropriate safety gear (e.g., safety glasses, face shields, proper clothing including hair coverings) and remove harmful jewelry
-
Housekeeping: Stop machines before cleaning, keep machines/tools clean, use benches to organize tools/materials, keep the floor free of oil and grease, return materials to storage, and use brushes to clean up chips.
-
Safe work practices: Understand how to stop machines quickly, disconnect power when making repairs, securely clamp workpieces, immediately obtain first aid for injuries, remove sharp edges from workpieces, lift heavy objects safely using proper lifting techniques, know fire extinguisher location and operation, know fire exit locations, and know fire alarm box locations and operating procedures.
-
Fire prevention: Follow procedures for lighting gas furnaces, know fire extinguisher locations and operation, know fire exit locations, know fire alarm box locations and operating procedures. Be careful to direct sparks away from flammable materials when using a welding or cutting torch.
