					Manufacturing Systems
What is Manufacturing?
 Manufacturing  is the making of parts
  and putting the parts together to make a
  product.
 Imagine your life without manufacturing
   What   would it be like?
 Weare all very dependent on
 manufacturing.
Manufacturing
 The    manufacturing industry is very
  important to our society.
 It is important to our economy.
 An economy is a system for producing
  and distributing products and services.
 Many citizens work in the manufacturing
  industry help produce products. They
  buy products with the money they earn.
Manufacturing
 The  more products people buy, the
  more products are manufactured. This
  allows more people to work.
 Look around the room. Think about all
  the manufactured products you see.
  How would you have to adjust to life
  without these products?
Value Added?
 Manufacturing   is important in another
  way.
 A piece of material is worth more after it
  has been changed into a useful product.
 That is called value added.
 The value is increased by the
  manufacturing process.
The Development of
Manufacturing
 In early days, families made their own
  products to make their lives easier.
 This type of production was known as
  the domestic production system.
 Any surplus (extra) was bartered
  (traded) for other supplies the family
  could not afford to buy.
 What could some of these items be?
The Development of
Manufacturing
 During  the Cottage Industry Period,
  families began to specialize.
 What do you think this means?
The Development of
Manufacturing
 During  the Cottage Industry, families
  were actually making goods to sell.
 Commercial manufacturing had begun.
 These families were not just making
  their own thins and selling the rest.
 Products were still handmade.
The Development of
Manufacturing
 The  factory system came into being in
  the 1800’s.
 Machines were being developed.
 Factories were introduced as places for
  manufacturing to continue to develop.
 These changes were being made to
  manufacturing during the Industrial
  Revolution.
Industrial Revolution
 The  Industrial Revolution refers to a
  time when great changes in society and
  the economy were caused by the switch
  from products being made by hand at
  home to products being made by
  machines in factories.
 Working conditions were very poor
  during this time.
The Development of
Manufacturing
 Today   manufacturing is still done in
  factories.
 How are modern manufacturing facilities
  safer and more efficient than old time
  factories?
 How does the safety aspect in
  manufacturing effect worker morale and
  productivity?
Types of Modern Production
 Thereare three basic types of modern
 production systems:
     Custom
     Job Lot

     Continuous

 Thetype of production system chosen
 depends on the kind of product to be
 made and the number or amount to be
 produced.
Custom Production
 Incustom production, products are
  made one at a time according to the
  customer’s specifications.
 Each product is different.
 This type of production is usually the
  most expensive per number of parts
  made.
Job Lot Production
 In job lot production, a certain quantity of a
  product, called a lot, is made.
 A job is producing one lot.
 Many seasonal items, such as lawn mowers
  and snow blowers are manufactured this way.
 Per part, this type of production is less
  expensive than custom production. The cost
  can be spread over more products.
Continuous Production
 Continuous  production is the system
  used for mass producing products.
 This means a large quantity of the same
  product is made in one steady process
  using an assembly line.
 Continuous production is the most
  economical type of manufacturing
  system.
Assembly Line Production
 In an assembly line, the product moves
  from one work station to the next while
  parts are added.
 This type of production is also called
  line production or mass production.
 An assembly line is set up an the
  products are continuously produced.
Who Does Manufacturing?
 Anyone  can Manufacture.
 Can you think of ways you might
  manufacture something using each type
  of production system?
What is a Company?
A   company is an organization formed by
  a group of people for the purpose of
  doing business.
 Large companies sometimes
  manufacture many different items. For
  instance, General Motors manufactures
  over 50 different types of cars and
  trucks.
Companies
 Sometimes    large companies own
  smaller companies that manufacture
  different products. The smaller
  companies are called subsidiaries.
 They are like separate companies but
  are controlled by the same parent
  company.
Manufacturing Systems
A  technological system is needed to
  efficiently produce manufactured
  goods.
 This system has:
      Inputs
      Processes

      Outputs

      Feedback
Inputs
   Input includes anything that is put into the
    system. The seven inputs in manufacturing
    are:
          People
          Materials
          Tools and Machines
          Energy
          Capital
          Information
          Time
Processes
 Processes  are all the activities that
  need to take place to make the product.
 There are two kinds of processes:
      Management – People who make decisions for
       the company.
      Production – People who physically help

       produce the product. They change the raw
       materials into a product.
Output
 The  result of inputs and processes is
  called output.
 One output is the manufactured
  product.
 Other outputs, such as waste and
  pollution, may not be expected, and
  they are certainly not wanted.
Impacts of Manufacturing
 The  outputs of a system affect us and
  our world.
 The outputs of a system have become
  so numerous and widely used that they
  have an impact on nearly every aspect
  of our lives.
Impacts of Manufacturing
 They affect our economy.
 They affect our society.
 They affect our politics.
 They affect our environment.
In Summary
 Manufacturing   is a system that
  produces products for our use.
 It uses inputs to create the desired
  outputs.
 The system is organized to change the
  form of materials, using material
  processing and management
  technologies.
In Summary
 The  activities within the system are
  controlled by company and society
  goals.
 If successful, manufacturing will provide
  goods at a fair price without harming the
  environment.
 The owners of the company should earn
  a profit.
