MAE 517 Advanced Precision Manufacturing for Products, Systems and Processes

3 Credit Hours

This is a graduate level course designed for graduate students and undergraduate seniors. This course examines precision issues for products, manufacturing machines, processes, and instruments. Modern manufacturing technologies are distinct in their multifarious nature in product sizes, materials, energy forms, theories, and information types; however, the key to their success relies on the management of precision. This course discusses issues critical to both existing precision manufacturing and future sub-micron/nano technology. Important topics include fundamental mechanical accuracies; manufacturing systems and processes; geometric dimensioning and tolerancing; process planning, tolerance charts, and statistical process control; principles of accuracy, repeatability, and resolution; error assessment and calibration; error budget; reversal principles; joint design and stiffness consideration; precision sensing and control; precision laser material processing.


Undergraduate courses in manufacturing (MAE496) or engineering design (MAE415) , equivalent, or consent of instructor.

Course Objectives

The goals of this course are to provide students in-depth knowledge related to precision manufacturing by focusing on the precision aspects of products, machines, processes, and process management. This focus on precision also provides a coherent treatment to unify products, machines, processes, and process management as one close-knit field. As a result, students, after completing this course, will have a systematic view of modern manufacturing and the skills to address the precision related problems for advancing productivity and quality.

Course Outcomes

By the end of this course, students will be able to:

  • Demonstrate a skill to apply basic principles related to fundamental mechanical accuracy.
  • Interpret critical errors in precision of products, machines, and processes.
  • Interpret geometric dimensioning and tolerancing in mechanical drawings.
  • Identify key components which constitute a precision machine tool.
  • Conduct error budget analysis with correct mathematical treatments.
  • Analyze data to maintain product quality.
  • Calibrate machines with correct precision principles.
  • Identify technologies critical to next-generation precision designs based on literature reviews and actual test data.
  • Be able to apply laser material processing for manufacturing.
  • Have the ability to read journal papers related to precision manufacturing.
  • Be able to relate the course materials to daily experience of living, in particular those related to precision performance, such as vehicle alignment, wood work, etc.
