- 10. Introduction What is Manufacturing? It is derived from two Latin words, Manus (Hand) and factus (make), so manufacturing means to make by hands. Manufacturing involves application of physical or chemical processes to alter shape, geometry, properties and Appearance of a given starting material and turn it into a useful and valuable product. It also includes assembly of multiple products to get something useful. It is always performed as a series of Operation, each step bring the material closer to its final product. Industry Product Quantity Material Processes
- 11. Industries Manufacturing Industries Industries comprises of enterprises and organizations that produce or supply goods and services Industries can be classified as Primary, secondary and tertiary Primary Industries: They cultivate and exploit natural resources such as agriculture, mining For E.g.: China Shenhua Energy. Secondary Industries: They take the output of the primary industries and convert them into consumer and capital good. The word manufacturing mainly applies to these industries, except construction and Power generation industries which are also considered secondary industries. Tertiary Industries: These constitute the service sector of the economy
- 12. Products Manufacturing Products The final products of manufacturing industries can be divided into two types: Consumer goods and Capital goods • Consumer goods: It includes the products directly purchased by the consumers such as: Car, computers, tires and tennis rackets. • Capital goods: These are purchased by companies to produce goods and/or to provide service. For E.g Aircraft, computer, medical equipment’s. Most of capital goods are purchased by service industries.
- 13. Quantity Production Quantity and Product variety The quantity of products made by factory has an important influence on the way its people , facilities and processes are organized Annual production quantities can be classified as: • Low production quantity: Range 1-100 units per year. • Medium production quantity: Range 100-10000 units per year. • High production quantity: Range 10000- million units per year.
- 15. Processes Manufacturing Processes Manufacturing processes are performed as unit operation, i.e. single step is performed in the sequence of steps to transform The required material into finished good. It has two categories: 1. Processing Operations 2. Assembly Operations. Processing operations uses energy to alter work parts shape, physical properties or appearance to add value to a material. The applied energy may be in the form of Mechanical, Electrical, thermal or chemical. Assembly Operations joins two or more components to create a new entity.
- 16. Processing Ops Shaping Operations: Alters geometry of the starting material by various methods such as: deformation, particulate Processing, machining etc. Property Enhancing Operations: Alter properties of the materials without altering its shape such as: Heat treatment. Surface finishing Operations: To clean, treat, coat or deposit material over the surface for protecting against corrosion and friction. Our subject is concerned here
- 17. Assembly In this section, components are either combined permanently or semi permanently, based on which, assembly operation can be divided into two main classification: Permanent joining and Mechanical Joining process Permanent Joining Process: Joints cannot be easily disconnected without damaging the material, such as welding, brazing, soldering, adhesive bonding. Mechanical Joining Process: These joining techniques allow easy disassembly of the components such as screws, bolts, rivets etc.
- 18. Shaping Operations • Solidification process: In which starting is heated liquid or semifluid that cools and solidifies to form a parts geometry. • Particulate Processing: Starting material is powder and the powder is heated and compacted into a desired geometry. • Deformation Process: In which starting material is ductile solid, which is than deformed to get the final geometry of a product. Why brittle material can undergo deformation processes? • Material Removal process: In which starting material is solid (Either ductile or brittle), from which material is removed so the resulting part is the desired geometry.
