Course Description

Covers creating drawings for existing 3 dimensional objects for reproduction. Explores multi-part assemblies and assembly drawings as well as assembly animations and their utilization in lean manufacturing. Continues development of tool use in 3d drafting software and solid modeling skills including application in reproduction of products. Prerequisites: MFG 211. Audit available.

Course Outcomes

Upon successful completion of this course, students will be able to:

  1. Create digital drawing of existing three-dimensional objects to tolerance.
  2. Create 3d multi-part assemblies using digital drafting software.
  3. Generate exploded assembly views for existing and new 3d blueprints.
  4. Generate exploded assembly animation.
  5. Produce / replicate existing three-dimensional object to tolerance.

Suggested Outcome Assessment Strategies

Outcomes are assessed through a mixture of hands on and written assessments.  Priority is given to hands-on proficiency-based assessment in an environment that rewards demonstration of skill needed for success in industry.

  • Lecture and in-booth coaching and direct instruction.
  • Direct instruction in full class demonstration of skills.
  • Written exams.
  • Student proficiency through demonstration of learned strategies and skills in industry standard environment.
  • Mock AWS Testing procedure (destructive testing) or mock local industry supported on-site testing procedures.
  • Job readiness based on performance.
  • In class lab experiments and testing using the scientific process with written result reporting.

Course Activities and Design

The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.

Course Content

Outcome #1: Create digital drawing of existing three-dimensional objects to tolerance.

  • Use precision measure tools with accuracy to accurately size drawing.
  • Understand the use of digital tool sets and how they interact and relate to physical precision measuring tools.
  • Determine which is the correct tool to use for measuring tasks.

Outcome #2: Create 3d multi-part assemblies using digital drafting software.

  • Create an assembly that has multiple parts to be created.
  • Machine and develop all necessary assembly pieces in house.
  • Develop an assembly procedure.

Outcome #3: Generate exploded assembly views.

  • Create an exploded assembly view.
  • Generate an accurate fastener list.
  • Produce an accurate parts list.

Outcome #4: Generate exploded assembly animation.

  • Create an exploded assembly animation showing assembly steps and procedures.
  • Include created tolerances, expected dimensions and all assembly steps.

Outcome #5: Produce / replicate existing three-dimensional object to tolerance.

  • Choose a 3d object to replicate and create a digital drawing.
  • Produce the part using available equipment from the drawing created.
  • Assemble and check tolerance of created part to drawing.

Suggested Texts and Materials

Resources are available openly on the web, but largely the curriculum adaptation needs to be done based on the instructors existing skill set.  Since there are many ways to teach the content, the “teach what you know, and teach well what you do” is very appropriate for courses like this.

Suggested/recommended text:

  • Print Reading for Welders 5th Edition Thomas E. Proctor, Jonathan F. Gosse

Suggested Resources:

  • AWS Structural Code Book 2020
  • Aeorspacewelding.com
  • Thefabricator.com
  • Aws.org

Students utilize on campus computer resources and software, e.g. CAD resources.

Department Notes

Safety glasses are required at all times in the manufacturing lab, and are provided for students. Students may also purchase their own safety glasses from a local supplier. Long pants and closed toed shoes are required in the welding lab at all times. Appropriate clothing must be worn to work in the lab (no synthetic materials, ect.). Safety requirements are covered prior to work in the lab.
