Transcript of Duration: 3 hours (4 class periods) The Big Idea:
• Duration: 3 hours (4 class periods)
• The Big Idea:
Manufacturing is the production of physical goods using a variety of mechanical processes
Lesson 2 Benchmarks
•13F Design and use instruments to gather data. 3
•13H Identify trends and monitor potential consequences of technological development. 3
•13I Interpret and evaluate the accuracy of the information obtained and determine if it is useful. 3
•19F Manufacturing systems use mechanical processes that change the form of materials through the processes of separating, forming, combining, and conditioning them.
Lesson 2 Benchmarks
•19G Manufactured goods may be classified as durable and non-durable. 4
•19H The manufacturing process includes the designing, development, making, and servicing of products and systems. 2
•Materials must first be located before they can be extracted from the earth through such processes as harvesting, drilling, and mining.
• Identify examples of mechanical processes that change the form of materials through the processes of separating, forming, combining, and conditioning them.
• Classify durable and non-durable manufactured goods.
• Solve simple problems involving rates and derived measurements for such attributes as velocity and density.
• Use graphs to show a variety of possible relationships between two variables.
• Describe the role of manufacturing in the United States and the world.
• Explain how manufacturing impacts their lives.
• Compare and contrast push and pull manufacturing processes
• SStandard: tandard: Students will develop an ability to assess the impact of products and systems.
• Learning Target: Recognize the impact of technology on our lives.
Warm-up Question:
• What have you used today that was manufactured?
• The construction of many of the same item at one time, usually using assembly lines and interchangeable parts.

How does manufacturing affect our lives?
• Cheaper goods• Better quality goods• Jobs, jobs, jobs,• Higher standard of
living
• Food • Fuel• Shoes and Clothes• Cars• Modular Homes• Integrated Circuit
Chip• Pencils and Pens
• Students will develop an understanding of and abilities to select and use manufacturing technologies.
• Learning Targets: 1. Identify examples of mechanical processes
that change the form of materials through the processes of separating, forming, combining, and conditioning them
2. Classify durable and non-durable manufactured goods
Manufacturing Processes• The form of materials is changed by:
1. Separating
2. Forming
3. Combining
4. Conditioning
Durable Goods• Do not quickly wear out. • May be used over and over
– Cars– Bricks– Electronics
• Non-durables include:– Food– Clothing– Paper products
Steps in Manufacturing
• Turning raw materials into finished goods on a large scale.– Obtaining and preparing raw materials– Processing the materials mechanically or
chemically– Assembling– Testing– Inspecting– Packaging
• SStandard:tandard: Students will develop an understanding of and abilities to select and use manufacturing technologies.
• Learning Target: Compare/contrast push and pull manufacturing processes.
Traditional Manufacturing
• Mass Production – – Uses interchangeable standardized parts that can
quickly be assembled– Breaks complex operations down into simple steps
that can be performed by unskilled workers
• A ‘PUSH’ Manufacturing system – Output from the first process in the sequence drives
the second process and so on
What's Up In Factories - 1
New Trends in Manufacturing
• Lean Production – – Less of everything is required to produce the same
quantity that traditional mass production generated– Less materials, equipment, manhours, time, effort,
capital
• A ‘PULL’ Manufacturing system that is driven by customers orders and need for specific parts
What's Up In Factories - 1
New Trends in Manufacturing• KANBAN • Cards that carry information from one process to
processes that come afterward
• Tell about what and how much to produce next.
• Identifies the type of part, how many there are, and other basic information.
• “Pulls” only needed parts
without maintaining extra
inventory
New Trends in Manufacturing
• Quality Circles – Employees, working in teams, set aside time to
review work procedures– Come up with ways of enhancing their
performance.
New Trends in Manufacturing
• KAIZEN – Continuous improvement– an on-going process involving a variety of
activities to reduce waste and inefficiency
New Trends in Manufacturing
• ANDON – A system to notify management, maintenance, and
other workers of a quality or process problem– Uses a signboard incorporating signal lights to
indicate which workstation has the problem
• SStandard: tandard: Students will develop an understanding of and abilities to select and use manufacturing technologies.
• Learning Target: Students demonstrate push and pull manufacturing processes.
Push Production
• As each person finishes his/her job, it is pushed to the next person.
Faster production.
Increased chance of error - less quality.
Pull Production
• Each person does not start a new part until their last one has been pulled from them.
Increased quality.
Slower production.
Push versus Pull Manufacturing
• PUSH – complete task as quickly as possible– Faster Production (more items made in shorter period of time)
– Less quality (more likely to make mistakes)
• PULL – complete task only when the previously completed item is removed or ‘pulled’– Slower production (more likely to have idle time)
– Increased quality
What is QC rate when 50 shirts are made and only 40 pass inspection?
• SStandard: tandard: Students apply appropriate techniques, tools, and formulas to determine measurements.
• Learning Targets1. Solve simple problems involving rates and
derived measurements for such attributes as velocity and density.
2. Use graphs to show a variety of possible relationships between two variables.
