      Manufacturing considerations and selection

      Lesson details

      Learning outcome

      I can explain how a range of factors affect manufacturing process selection in industry.

      Key learning points

      1. Manufacturing process selection depends on a range of factors.
      2. Different processes are suited to different product types.
      3. CAM improves the efficiency of manufacturing processes, particularly for high-volume production.

      Keywords

      • Scale of production - the amount/volume of goods produced

      • CAM - Computer Aided Manufacture

      • Lead time - the length of time from order to production completion

      • Efficient - using materials in a way that minimises waste

      • Automation - use of technology to perform tasks

      Common misconception

      Manufacturing process selection is solely based on cost.

      Factors like product complexity, material properties, production volume, and lead time also play crucial roles.

      Teacher tip

      Use real-world examples of products and their manufacturing processes to make the concepts more relatable and show how different factors influence decisions in industry.

      6 Questions

      Q1.
      is commonly used in mass production as it allows for automation and consistent quality.

      Correct Answer: CAM, Computer Aided Manufacture

      Q2.
      Which factor is most important when choosing a manufacturing process for a product needed urgently?

      Material properties
      Correct answer: Lead time
      Worker experience
      Product aesthetics

      Q3.
      Arrange the following manufacturing processes in order of shortest to longest lead time:

      3 - Handcrafting

      Q4.
      Match the factor to its impact on manufacturing:

      Correct Answer:Scale of production,Determines if automation is needed

      Determines if automation is needed

      Correct Answer:Material properties,Affects the choice of process (e.g. cutting, moulding)

      Affects the choice of process (e.g. cutting, moulding)

      Correct Answer:Lead time,Influences how quickly products need to be made

      Influences how quickly products need to be made

      Q5.
      A larger scale of production usually leads to a more process to reduce time and costs.
