Effective Geometric Dimensioning & Tolerancing in Houston, TX

Due to variations in the manufacturing processes, manufactured items differ in size and dimensions from the original CAD model. To optimally control and communicate these variations, engineers and manufacturers use a symbolic language called GD&T, short for geometric dimensioning and tolerancing. It is a system of symbols, rules, and definitions that define the geometry of mechanical parts.

HAK Metrology in Houston, TX, has real-world industrial experience with the application and understanding of GD&T. It is one of the most powerful tools available to improve quality, reduce cost, and shorten delivery time. GD&T is a team effort as it involves collaboration between engineering, production, and quality assurance teams.

Preparing for GD&T Implementation

GD&T on the drawing must first and foremost capture design intent. To do this accurately, the concurrent engineering team should be involved in the creation of the drawing.

Common place is that you do not describe manufacturing processes in the design drawing, as this can negatively impact clarity. Whenever possible, you should leave GD&T to the experts who have the skills, tools and knowledge to perform this task effectively.

If you're not sure how to best prepare your product or drawing for GD&T, HAK Metrology will offer advice on how best to do this.

Symbols of Geometric Dimensioning & Tolerancing

For GD&T, the latest version of the ASME Y14.5 Standard is Y14.5-2018. However, Y14.5M-1994 and Y14.5-2009 are still relevant and used by certain industries or from legacy drawings.

Here is a list of the main GD&T symbols used by the ASME Y14.5 Standard:
