GD&T Training

Description GTOL or GD&T training

GD&T or sometimes referred to as Gtol is an essential tool for communicating design intent so that parts from detailed drawings & annotations within the part database maintain the desired form, fit, function, and interchangeability. By providing uniformity in detail drawing & model-based definition specifications and interpretations, GD&T reduces guesswork throughout the manufacturing process improving quality, lowering costs, and shortening delivery times. This manufacturing communications course covers the combination of lectures, Creo and or SOLIDWORKS examples, various study aids to facilitate your understanding plus use cases of both Model Based Definition MBD coupled with Geometric Dimensioning and Tolerancing GD&T. Applying this geometric language to industry examples inside the CAD tool facilitates learning and enhances discussions. Theoretical knowledge is enhanced with practical knowledge through practicing in Solidworks or Creo.

Prerequisites

Some knowledge of Creo or Solidworks *relative to the class they are taking is all that is necessary.

Who should attend this 16hr or 40 hr Learn GD&T course: Both fabrication technicians in the shop including outside partners & vendors. Also engineering managers, detailers, design engineers + inside & outside design/engineering contractors & vendors. For this communication process to be accepted, this comprehensive course has championed for full adoption of this process.  Technicians and managers are less excited to take this course especially because we use your CAD tool… Creo or Solidworks, however, it’s important for overall success because ‘process acceptance’ starts with the top. In a cost-sensitive manufacturing environment, it’s more expensive to not take this course. We mean by improving manufactured quality, lowering production costs, and shortening delivery times. smoother communication where less scrap affects the bottom line.  

GD&T experts have revised GD&T Y14.5 for modern applications as well. Because of the widespread use of computer-aided design and the industry transition toward reduced use of orthographic views for product definition MBD, model views were added in many figures throughout the Standard. This revision also emphasizes the use of profile for location tolerances applied to surfaces. You’ll leave this course equipped to read, interpret, understand and apply GD&T on Creo and Solidworks models and subsequent detailed drawings. This course will empower you and your team to work more confidently, communicate more clearly, and produce parts more efficiently. Consider your entire team and sign up for this course today.
