MFG 251

Course Description

Builds upon metal additive techniques learned in MFG 251. Involves printing parts requiring more specific final dimensions, engaging in more rigorous model preparations required to mitigate problems associated with close tolerance geometry. Explores production strategies to achieve tightly toleranced part dimensions, starting with additive techniques and moving on to reductive finishing methods. Introduces strategies to print at near net shape, with excess material on critical surfaces to be cut with precision reductive CNC machines. Includes printing in highly challenging materials, such as titanium, which require specific powder handling techniques and model preparations due to metallurgical properties such as thermal expansion/contraction, conductivity/dissipation. Prerequisite: MFG 251. Audit available.

Course Outcomes

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

  1. Perform calibration procedures necessary for optimization of accuracy in metal additive manufacturing equipment.
  2. Develop production orientated strategies for large scale longer duration builds.
  3. Use geometry offset planning and requisite math for near-net shape manufacturing of technical parts.
  4. Optimize print efficiency and orientation strategies for complex parts.
  5. Perform root cause analysis of failed or out of tolerance builds, and plan program changes to address them.
  6. Utilize mixed process strategies to produce to tolerance parts, including using reductive post processing programming.

Suggested Outcome Assessment Strategies

The determination of assessment strategies is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: writings (journals, self-reflections, pre writing exercises, essays), quizzes, tests, midterm and final exams, group projects, presentations (in person, videos, etc), self-assessments, experimentations, lab reports, peer critiques, responses (to texts, podcasts, videos, films, etc), student generated questions, Escape Room, interviews, and/or portfolios.

Department recommended assessment strategies:
  • Lecture and in-lab coaching and direct instruction.

  • Full class demonstration of skills.

  • Written exams

  • Student proficiency through demonstration of learned strategies and skills in industry standard environments

  • Job readiness based on performance

  • In class lab experiments and testing using the scientific process with written result reporting

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 manufacturing labs 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.
