Transcript of Engineering In Manufacturing

  • 1. Design Engineering Processes
    • After completing this unit, you will know about:
    • The role of engineering in the manufacturing company
    • The six stages of the design engineering process
    • The use of Design Criteria
  • There are three assignments that are part of this unit:
    • The first two are to be completed individually
    • The third is to be completed as part of a team effort

2. Engineering in Manufacturing

  • Engineers are the problem-solvers in manufacturing companies.
  • They design products & plan the most efficient manufacturing system to produce the product.

3. Introducing Design Engineering

  • Design Engineers create ideas for products.
    • They develop these ideas into plans.
    • They decide if a profit can be made by producing the product.
    • They make designs, models, and engineering drawings to help develop and test the ideas.

4. Design Engineering Processes

  • Design Engineering begins with theresearch and developmentof new product ideas.
  • Research and Development is also called R&D.
    • Identifies & develops new ideas for products, materials, and processes.

5. Research

  • The Research part of R&D is the step-by-step search for new information, facts, and principles about a topic.
  • Research is very methodical(meaning it uses a method or process).
    • Two types:
      • Pure Research(also called Basic Research)
        • Search for new information without thinking about the use of that information
      • Applied Research
        • Search for practical applications for the new knowledge found through Pre Research

6. Development

  • The Development part of R&D is a type of applied research that tries to:
    • Create new products
    • Create new applications for existing products
  • Development takes new materials or product ideas discovered by researchers and creates new products.

7. Research & Development Questions

  • Before engineers decide to manufacture a product, they ask three basic questions:
  • Can the product be made with our equipment?
  • Will customers buy it?
  • Can it be sold at a profit?
  • ASSIGNMENT # 1 (complete individually)
  • Write a complete paragraph for each of the three questions listed above and explain why these questions are important and how an engineer might find the answers.
  • Write a complete paragraph to explain why engineers would try to find new applications for existing products?

8. Stages in the Design Engineering Process

  • Six Stages of the Design Engineering Process:
    • Desire
    • Preparation
    • Ideation
    • Incubation
    • Illumination
    • Verification

9. Stage 1: Desire

  • Desire
    • The engineer must have the desire to create a new design
    • The engineer must be interested in the product
    • Also called motivation
    • Desire provides the energy, interest, and motivation for the engineer to complete the job

10. Stage 2: Preparation

  • Preparation
    • Stage of the engineer learning, exploring, and gathering information
    • doing your homework time
    • Engineers study existing products
    • Talk to experts
    • Talk to potential customers
    • Study tools, processes, and materials
    • Must develop theDesign Criteria

11. Stage 2 continued: The Design Criteria

  • Preparation:The Design Criteria
      • Function
        • What is the product is designed to do?
      • Form
        • What is the size, shape, and structure of the product?
      • Ergonomics
        • Is it designed for comfortable human use?
      • Aesthetics
        • Is it considered visually appealing?
      • Ease of Manufacture
        • Can the company make the product?
      • Standardization
        • Does it use standard tools, parts, and sizes?
      • Durability
        • What is the expected life of product?
      • Costs
        • Can it be sold at a profit?

12. Stage 3: Ideation

  • Ideation
    • Brainstorming for ideas
      • Provides ideas for possible products
    • Sketching ideas
      • Thumbnail sketches (rough sketches)
    • Renderings
      • Shows all details of the finished product
    • Mock-ups
      • Scale model of actual product
        • Made from easy-to-use materials
        • No real working parts

13. Stage 4: Incubation

  • Incubation
    • Take a break
    • Ponder
    • Reflect
    • Think

14. Stage 5: Illumination

  • Illumination
    • New ideas generate subconsciously
    • Ah ha! stage
    • The light bulb goes on!

15. Stage 6: Verification

  • Verification
    • Prove the idea
    • Make sure the product actual works!
    • Build a Prototype
      • Actual materials
      • Working components
    • Testing
      • Does it meet the Design Criteria?

16. Engineering in Manufacturing

  • ASSIGNMENT # 2 (complete individually)
    • Write a complete paragraph for each of the Design Criteria.
    • Explain why each of the eight factors are important in the manufacturing process.
      • The Design Criteria questions:
        • What is the product is designed to do?
        • What is the size, shape, and structure of the product?
        • Is it designed for comfortable human use?
        • Is it considered visually appealing?
        • Can the company make the product?
        • Does it use standard tools, parts, and sizes?
        • What is the expected life of product?
        • Can it be sold at a profit?
