GD&T Inspection

A practical course bridging the gap between drawing requirements and effective inspection practices.

The GD&T Inspection course provides a practical understanding of inspection considerations based on the drawing requirements. It focuses on real-world applications, bridging manual inspection methods with digital equipment such as CMM inspections. Participants will learn the GD&T inspection mindset - how to simulate part setups, measure parts using metrology equipment, and report inspection results.

And, GD&T Inspection isn't just for inspectors; it's designed for anyone involved in the lifecycle of a manufactured part. Understanding how a part is inspected is critical for making the right decisions as a machinist, design engineer, or manager.

GD&T Inspection Course - FAQs

Why do I need the GD&T Fundamentals prerequisite before taking the GD&T Inspection course?

The GD&T Inspection course expands upon the concepts taught in the GD&T Fundamentals course, and explores the translation of GD&T interpretation into tangible physical inspections. Understanding how to interpret GD&T (covered in Fundamentals) is crucial; without it, inspecting GD&T becomes challenging. It's essential to first understand the requirements indicated by GD&T callouts on the drawing to effectively evaluate if a part meets those specifications.
How does this course differ from the GD&T Fundamentals course?

While the Fundamentals course explores the "what & why" of GD&T, the GD&T Inspection course focuses on the real-world "how" from an inspector's perspective. The act of interpreting GD&T significantly differs from the inspection of GD&T. Techniques related to inspection methods and reporting criteria are not taught in Fundamentals.
Is the course content updated to reflect the latest industry standards and practices?

The course is structured based on the ASME Y14.45 Measurement Data Reporting standard, with an objective to provide a standardized procedure for reporting a feature's compliance. However, as stated in our GD&T Fundamentals course, the interpretation of the fundamentals of GD&T remains the same, regardless of the chosen standard (ISO or ASME). Equally important is the fact that none of these standards dictate HOW we verify that a part meets the specifications of GD&T. Part conformance is left up to the professional’s discretion and the processes they choose.
Are there any hands-on exercises, simulations, or real-world examples included in the course?

Our lessons utilize real world drawing examples and have high quality animations, graphics, and videos of metrology equipment and setups to give a very real world experience that you can take back to your job the very next day.
What kind of support is available beyond course completion?

All of our live instructor training programs come with direct instructor support – access to our email support provides tailored answers directly from our professional certified GD&T instructors. Additionally, all users will receive 90-day access to our online platform – including our bonus learning content. You’ll receive access to our library of previously recorded webinars and bonus video content.
How does the course content translate to real-world application? Will it be relevant to my current job or future career?

This course equips learners with bare minimum requirements to check a feature to see if it meets the GD&T requirements using common hand tools. We then expand upon that and help the students to extrapolate that to more applicable scenarios that learners encounter during their daily inspections. The experience gained in comprehending how manual inspections verify specifications empowers students to easily transition to other inspection procedures for any given part or feature.
