Course Description

Course Length: 16 hours

Presentation: 4 sessions - 4 hours per session

This course is designed for those who use the ASME Y14.5 - 2009 Dimensioning and Tolerancing standard. This course covers all of the geometric dimensioning controls used on mechanical engineering drawings.  Theoretical and practical concepts of each of the geometric controls are explained relative to design, tooling, production, and inspection.  Engineering drawings are used extensively in this training.

This is an online, instructor-supported course, and presented by alive instructor. The course is scheduled in advance and each session will be 4 hours. There will be material provided to each participant.

There will be re enforcement quizzes conducted throughout the training. A final exercise will be administered upon completion.
