Learn about the fundamentals of preparing DFMEA for Mechanical design engineers

What you'll learn
Why do we prepare DFMEA?
What are failure modes in mechanical design and how do we define them ?
What are root causes & mechanisms? how to find root causes for failure modes ?
What is Severity, Occurence and Detection of Failure ?
Grading of Severity , Occurrence and Detection ratings
What is Boundary or B diagram ? How to develop it with examples
What is Parameter Diagram or P diagram ? How to develop it with examples
Examples with simple mechanical products
DFMEA process walk-through and exercises
Requirements
Course is best understood with a basic prior understanding of mechanical design engineering as it is primarily directed towards design engineers already designing systems
Description
Design Failure Mode Effect and Analysis (DFMEA) is a very important tool for the design engineer to develop designs which are reliable and safe. This course will take you through the concepts and process of developing a DFMEA.What the course will cover? Need for DFMEADefining failure modesCause and Root cause analysis using Fishbone diagramsEvaluation of Risk - Severity, Occurence and DetectionWhat is Design prevention control and Design detection control / Design verification Grading of severity, occurence and detectionThe systematic process of DFMEAWhat is B diagram and how to prepare B diagram with multiple examplesWhat is P diagram and how to prepare P diagram with multiple examplesDFMEA walkthrough of a Bicycle Exercises for learning by doing.The course is well suited for Mechanical design engineers or aspiring students who want to learn how to design effectively and consider possible failure modes. The class focusses on the concepts and underlying reasoning rather than a descriptive approach . Developing a good DFMEA is critical for complex system engineering work and hence its a key skill to develop for career growth and innovation.
