Geometric Dimensioning and Tolerancing 

GD&T Training

Geometric Dimensioning and Tolerancing (GD&T) is a symbolic language used in engineering and manufacturing to define and communicate design specifications. It enhances clarity and precision by specifying functional tolerances for size, form, orientation, and location of features on a part or assembly. When implemented well, GD&T ensures that parts fit together accurately and function as intended.

At Indicate Technologies, we offer comprehensive GD&T training programs to equip individuals with the knowledge and skills to interpret and apply GD&T principles effectively. Our courses cover the fundamentals of GD&T, including symbols, datums, tolerances, and measurement techniques. Participants gain practical insights into interpreting engineering drawings, creating proper tolerancing schemes, and optimizing manufacturing processes. Our goal is to empower professionals with the expertise to improve quality, reduce costs, and enhance communication within the design and manufacturing industry.

8 Tracks to GD&T Expertise

Our classes can be used to address deficiencies in the process chain and bridge the gaps between Design, Manufacturing, and Inspection. This is part of an organization's successful adoption of GD&T practices.

Dr. Greg Hetland is our GD&T expert who leads this effort. He has designed several educational tracks. The contents of each track are intended to support and optimize particular job functions as they participate in the transformation to GD&T implementation. Each track is a grouping of classes designed for particular job functions.

Our GD&T Training:

The core of each education track consists of the following two classes which are offered frequently. These provide the basis for an organization's adoption of GD&T as an ongoing effort and process. As new members are added to your team, before becoming critical players in your GD&T program, they can be brought up to speed through attending these classes.

Other supporting classes are offered periodically. Once the fundamentals are in place via the core classes, additional classes are delivered for individual organizations often at their facility. In this way, your adoption of GD&T is supported and maintained. Having an ongoing offering that addresses all roles involved is our attempt to help you avoid the trap of a failed effort to adopt GD&T within your organization. A single application of a few classes with a few engineers is typically not sufficient to transform a company with respect to its use of GD&T. Successful transformation is cultural, happens incrementally, building on individual successes and expanding over time. We are here to help you achieve that.

Class: Intermediate Principles

To establish a fundamental comprehension of mechanical drawings, the focus lies on employing linear tolerancing and GD&T (Geometric Dimensioning and Tolerancing) for designing, manufacturing, and inspecting parts. This involves implementing geometric controls in accordance with ANSI / ASME or other relevant national standards.

Improved Communication: GD&T provides a standardized language for communicating design specifications. It ensures that engineers, designers, and manufacturers have a clear and unambiguous understanding of the requirements, reducing errors and misunderstandings.

Enhanced Quality: By precisely defining tolerances, GD&T helps achieve tighter control over part dimensions and geometric features. This leads to improved product quality, as parts fit together correctly, reducing assembly issues and ensuring proper functionality.

Cost Reduction: GD&T allows for more efficient manufacturing processes by specifying tolerances based on functional requirements rather than arbitrary values. This enables manufacturers to optimize production methods, reduce scrap and rework, and minimize costly iterations.

Interchangeability and Assembly Ease: GD&T facilitates the interchangeability of parts, ensuring compatibility and interchangeability across various manufacturing processes. It enables the assembly of components from different suppliers, leading to increased flexibility and cost savings.

Design Optimization: GD&T encourages designers to think beyond basic dimensions, promoting innovative solutions and efficient designs. It allows for the optimization of part designs, material usage, and manufacturing processes, resulting in improved performance and reduced manufacturing costs.
