  • Slide 2
  • Principles of Manufacturing Technology What is Manufacturing Technology or Manufacturing Engineering Systems Manufacturing is the use of machines, tools and labor to make things for use or sale. The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale. 2 Eng. Nkumbwa
  • Slide 3
  • Principles of Manufacturing Technology Such finished goods may be used for manufacturing other, more complex products, such as: Household appliances Automobiles Other products sold to wholesalers, who in turn sell them to retailers, who then sell them to end users - the "consumers". 3 Eng. Nkumbwa

  • Understanding Manufacturing Systems Engineering Modern manufacturing includes all intermediate processes required for the production and integration of a product's components. Some industries, such as semiconductor electronics and steel manufacturers use the term fabrication instead. 5 Eng. Nkumbwa
  • Slide 6
  • Understanding Manufacturing Systems Engineering The manufacturing sector is closely connected with engineering and industrial design or industrial engineering. Examples of major manufacturers include: North America include: General Motors Corporation, General Electric, Pfizer. Examples in Europe include : Volkswagen Group, Siemens, and Michelin. Examples in Asia include Toyota, Samsung, and Bridgestone. Example in Zambia include: ZamSugar, ZamBrew, Lafarge, Zambezi, Trade kings, Uniliver, TAP, Kafue Steel, Amanita, Zambeef, Parmalat, Milling Co., Plastic Co., Indeni, Scaw, etc 6 Eng. Nkumbwa

  • Economics of Manufacturing According to some economists, manufacturing is a wealth-producing sector of an economy, whereas a service sector tends to be wealth- consuming. 10 Eng. Nkumbwa
  • Slide 11
  • Economics of Manufacturing Manufacturing is a huge component of the modern economy. Everything from knitting to oil extraction to steel production falls under the description of manufacturing. The concept of manufacturing rests upon the idea of transforming raw materials, either organic or inorganic, into products that are usable by society. 11 Eng. Nkumbwa

  • Slide 15
  • So, What is Manufacturing? According to Webster's, Manufacturing is the making of goods or wares by manual labor or by machinery, especially on a large scale, from raw materials or unfinished materials. It is the making of a finished product or goods. 15 Eng. Nkumbwa
  • Slide 16
  • Manufacturing Methods There are different manufacturing methods namely: Batch Production Job Production Continuous Production 16 Eng. Nkumbwa
  • Slide 17
  • Batch Production Batch production is the manufacturing technique of creating a group of components at a workstation before moving the group to the next step in production. Batch production is common in bakeries and in the manufacture of sports shoes, pharmaceutical ingredients (APIs), inks, paints and adhesives. In the manufacture of inks and paints, a technique called a colour-run is used. 17 Eng. Nkumbwa
  • Slide 18
  • Batch Production A colour-run is where one manufactures the lightest colour first, such as light yellow followed by the next increasingly darker colour such as orange, then red and so on until reaching black and then starts over again. This minimizes the cleanup and reconfiguring of the machinery between each batch. 18 Eng. Nkumbwa
  • Slide 19
  • Job Production Job production, sometimes called jobbing, involves producing a one-off product for a specific customer. Job production is most often associated with small firms (making railings for a specific house, building/repairing a computer for a specific customer, making flower arrangements for a specific wedding etc.) but large firms use job production too. 19 Eng. Nkumbwa
  • Slide 20
  • Continuous Production Continuous production is a method used to manufacture, produce, or process materials without interruption. This process is followed in most oil and gas industries and petrochemical plant and in other industries such as the float glass industry, where glass of different thickness is processed in a continuous manner. Once the molten glass flows out of the furnace, machines work on the glass from either side and either compress or expand it. Controlling the speed of rotation of those machines and varying them in numbers produces a glass ribbon of varying width and thickness. 20 Eng. Nkumbwa
  • Slide 21
  • Cell Production Cell production involves both machines and human workers. In conventional production, products were manufactured in separate areas (each with a responsibility for a different part of the manufacturing process) and many workers would work on their own, as on a production line. In cell production, or cellular manufacturing workers are organized into multi-skilled teams. Each team is responsible for a particular part of the production process including quality control and health and safety. Each work cell is made up of one team who deliver finished items on to the next cell in the production process. 21 Eng. Nkumbwa
  • Slide 22
  • Mass Production Mass production (also called flow production, repetitive flow production, series production, or serial production) is the production of large amounts of standardized products, including and especially on assembly lines. i.e. Elsweedy in Ndola. The concepts of mass production are applied to various kinds of products, from fluids and particulates handled in bulk (such as food, fuel, chemicals, and mined minerals) to discrete solid parts (such as fasteners) to assemblies of such parts (such as household appliances and automobiles). 22 Eng. Nkumbwa

  • Lean Production Lean Production, which is often known simply as "Lean", is a production practice that considers the expenditure of resources for any goal other than the creation of value for the end customer to be wasteful, and thus a target for elimination. Working from the perspective of the customer who consumes a product or service, "value" is defined as any action or process that a customer would be willing to pay for. Basically, lean is centered around preserving value with less work. Lean manufacturing is a generic process management philosophy derived mostly from the Toyota Production System (TPS) (hence the term Toyotism is also prevalent) and identified as "Lean" only in the 1990s. It is renowned for its focus on reduction of the original Toyota seven wastes to improve overall customer value, but there are varying perspectives on how this is best achieved. 24 Eng. Nkumbwa
  • Slide 25
  • Agile Production For the past ten years a quality revolution has arose because now, the marketplace has become global. A sophisticated and aware customer base has grown because of the increase of service industries where the customer plays a direct role in the delivery process. No longer can companies assume they can put out products to customers at the manufacturers schedule and quality levels. Many companies have realized this. Many have researched for was to make positive changes, which will permit them to identify, and quickly respond to the customer likes and complaints. At the same time, these changes must allow the manufacture the ability to get their products quickly to market. 25 Eng. Nkumbwa
  • Slide 26
  • Agile Production This is known as Agile Manufacturing. Agility means to have the ability to change quickly. The development of manufacturing support technology, which permits marketers, designers, and production personnel the ability to share a common database of parts and products, is one contributing factor a manufacturer must have in order to become an agile manufacturer. Goldman et al. (1995) suggest that Agility has four underlying components: deliver value to the customer; be ready for change; value human knowledge and skills; form virtual partnerships. 26 Eng. Nkumbwa
