Introduces digital design using modern CAD programs in two dimensions and introduces three dimensional drawings. Explores basic dimensioning to Geometric Dimensions and Tolerancing as used in blueprints. Covers multi-view drawings, part and assembly drawings. Prerequisites: MFG 155. Audit available.
Upon successful completion of this course, students will be able to:
- Understand digital print layout and formats.
- Utilize multi-view drawings to create digital blueprints.
- Create assembly drawings for the fabrication of multi-part assemblies.
- Generate accurate first and third angle projection of common 3d objects.
- Use Geometric Tolerancing and Dimensioning to accurately describe parts and assemblies.
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.
Outcome #1: Understand digital print layout and formats.
- Know the different components of different types of print layouts and symbols.
- Accurately fill out a blueprint with necessary information for referencing and later use and fabrication.
- Use appropriate symbols to describe the intended finished product.
Outcome #2: Utilize multi-view drawings to create digital blueprints.
- Understand and accurately draw and dimension orthographic projection of top view.
- Understand and accurately draw and dimension orthographic projection of side view.
- Understand and accurately draw and dimension orthographic projection of front view.
- Display knowledge of which view to use, when and how.
Outcome #3: Create assembly drawings for the fabrication of multi-part assemblies.
- Determine appropriate assembly procedure of developed multi-part assembly.
- Draw a complete basic assembly drawing.
- Draw an Exploded View assembly drawing.
Outcome #4: Generate accurate first and third angle projection of common 3d objects.
- Identify the difference between usage and drawing in first and third angle projection.
- Create a first angle projection of a 3d object.
- Create a third angle project of a 3d object.
Outcome #5: Use Geometric Tolerancing and Dimensioning to accurately describe parts and assemblies.
- Understand the symbols specific to GD&T.
- Describe and know the difference between GD&T and regular tolerances.
- Apply GD&T to a existing blueprint to describe necessary tolerances and sizing.
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.
- Print Reading for Welders 5th Edition Thomas E. Proctor, Jonathan F. Gosse
- AWS Structural Code Book 2020
- Amatrol Learning Systems Curriculum
Students utilize on campus computer resources and software, e.g. CAD resources.
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.
