This unique GD&T course integrates and combines the learning of GD&T with measurement and inspection techniques. The course gives the participant a practical and easy understanding of GD&T as it applies to the ANSI/ASME Y14.5M-1994 standard including changes made in the 2009 standard, along with exposure to inspection methods that are commonly available in manufacturing and quality. The course covers both the basic and mid-level GD&T concepts in easy to understand explanations and uses print reading exercises containing GD&T callouts throughout the program. Exposure to measuring fundamentals as it applies to GD&T will be demonstrated through the use of standard measuring tools and inspection equipment. This course is ideal for anybody who measures any GD&T callouts including engineers, quality technicians, and manufacturing machinists. Many interpretations of both GD&T callouts and inspection methods are made. Some may be correct; many are not. This course highlights what is right and wrong and clarifies some common mistakes.

Prerequisite:
A basic understanding of reading prints is recommended for all participants prior to attending this class. In addition, students should have some knowledge of basic measuring instruments. For students without much experience with measuring instruments, it is recommend that they first attend a course on dimensional measurement and metrology, such as Mitutoyo course #102, Dimensional Metrology, prior to attending this course.
Instructor:
David King has over 40 years experience in industry. His background includes completion of a 4-year tool & die apprenticeship, honors graduate of Mohegan College, and is a certified ASQC Mechanical Inspector. As an adjunct instructor in the Connecticut Community Technical College System, he has developed many courses including Print Interpretation, Basic Metrology, Layout Inspection, Operator Certification Programs, and Understanding Metrics. As a project engineer in industry, he has developed numerous manufacturing techniques and processes.
Mitutoyo and its Institute of Metrology is a worldwide organization. We are proud to state that more than 200,000 engineers have attended our metrology seminars over the years.
