Course Outcomes

Machining and Production Processes

Become familiar with common machining and production processes and their capabilities. Specify appropriate dimensional tolerances and surface finish for given applications based on a knowledge of machine capabilities and standard charts.

Feature Control Practice

Gain familiarity with manufacturing feature control practice using geometric dimensioning and tolerancing principles. Application of GD&T to assemblies.

Inspection Equipment/Datums

Experience with electronic and computer-based inspection equipment. Understand how functional gages are designed and used for inspection and part acceptance.

Understand the role of datums in design, production and inspection.

Stackup Model and Assembly Tolerance

Apply statistical tolerancing techniques to model stackup in assemblies. Learn techniques for establishing optimum tolerances for each assembly, based on the processes, geometry and materials.

Process Variations

Learn how to model process variations in 1-D and 2-D assemblies and predict the effect on critical features, product performance, and quality levels.

Assembly Model Variations

Learn how to account for dimensional, GD&T, and kinematic variations in an assembly model, both statistically and worst case.

Competing Tolerance Requirements

Recognize the competing tolerance requirements between production processes, design performance and overall cost.

Computer Applications

Develop an overall perspective of computer applications in design for manufacturing.
