Title: Modeling and Documenting a Sheet Metal Component

Summary Report

Name of NGM Educator:

Rebecca Marra, Drafting Dept. Head, Vinal Tech High School, Milford, CT

 

Name of Host Company:

Pennsylvania Globe

 

Grade Level:

9 - 12th

 

Student Work Types:

  1. Schema Activator - Most students are familiar with the washing machine.   Have the class take a look back in time and review the development of this common household appliance and the important role sheet metal played.  Assignment:  review the washing machines word document with the class.  washing machines.doc
  2. Vocabulary - Every student should be confident with the use of terms when being introduced to a new content area.  These are vocabulary terms defined and a matching worksheet to assist the student with identifying the words.  sheet metal terms.doc, sheet metal terms-matching.doc
  3. Identification - The application of newly acquired terminology allows the student to gain confidence and learn content quicker.  The use of this labeling worksheet gives the student another venue to apply their knowledge.  sheet metal label illustration.doc
  4. Applied Mathematics - the application of basic math functions and understanding is critical to the successful completion of the project.  These worksheets allow the student to have guided practice for the mathematics required.  A deeper understanding of what is happening to the metal when sheet metal is being bent is the goal.  bend allowance worksheet 1.doc
  5. Reading for Knowledge - Our school has a strong belief and practice to engage the student in reading whenever possible.  This guided reading activity will allow the student to have a silent sustained reading time and learn how sheet metal applications have a direct impact on the world around them.  SHTMTL-WALLEET.pdf, SM-WALL-ST-GUIDED READING.doc
  6. Solid modeling a sheet metal component - The student will complete a sheet metal bracket using the SolidWorks software application.  A drawing of the component and the flat pattern required to manufacture will be completed.

Task Abstract:  Create a solid model and drawing for a sheet metal component using the SolidWorks software application.

Task Objectives:   

  • The student will be able to identify products that use sheet metal applications;
  • The student will be able to identify and apply sheet metal terminology;
  • The student will be able to apply sheet metal bending formulas to determine flat pattern size;
  • The student will be able to apply the sheet metal module of SolidWorks to compelte a component and a drawing giving the appropriate flat pattern required for manufacturing.
Essential Understandings/Questions:  What is a pattern or stretch out?  How is it used to create everyday items?  Patterns are made of a material in a flat state which is intended to be bent or folded into a specified shape.  How are developments used in our everyday life?  Patterns are used to create ordinary items.  Some of these items are clothing, shoes, wallets, and purses, while the aerospace, automotive and construction industries are also common venues for development applications.
Task Description:  Upon completion of theory, worksheets and reading assignment, the students will Solid model a sheet metal component using the appropriate sheet metal applications within Solid Works and applying common sheet metal practices.  The part will be applied to a drawing and an accurate flat pattern will be given.
Resources Required - Computer station with SolidWorks CAD software, teacher created lesson plan and accompanying activities, printing station
Prior Learning Required  (i.e. prerequisite subjects if applicable) - Basic training in SolidWorks software applcation, understanding and ability to perform basic Orthographic Projection, ability to read blueprints, basic mathematical computation.
Context within which the work was produced (i.e. environment) - This sheet metal project is to be completed in a classroom setting and encompass 3 days of theory, demonstrations and activities.
Individual or Group Work - This project is intended to be an individual product.  The student could then be matched up with an HVACR student and complete the actual component from the documentation that is created using sheet metal if there is the appropriate departments available.
Special needs - The worksheets provided with this curriculum allow for a variety of learner types.

Educator Comments, Reflections, Suggestions - The sheet metal assignment was intended to enhance the development segment within my curriculum.  There are many other applications which could assist in student learning and applications.  Each teacher should look to identify a product within their area to enhance the curriculum.

All around us is the growing trend to "think green."  I look forward to sharing with the students the concept of light pollution and how it is affecting the lighting industry.  There are so many ways to protect the earth while saving money and there will be students interested in learning about this area.
