The new ASME standard contains numerous changes that affect the specification and interpretation of geometric tolerancing.
The course focuses on a major topics that must be mastered to be fluent in the fundamentals of geometric tolerancing. It tells the manufacturing staff and machines what degree of accuracy and precision is needed on each controlled feature of the part. Material that builds and develops critical thinking skills is contained within each topic, with questions that utilize those skills at the end of each chapter.
A datum feature is a physical feature of a part identified by a datum feature symbol and corresponding datum feature trianglee.
Each goal is defined and supported by a set of performance objectives. The course can be purchased for, or day access.
