This course was developed to meet your GD&T applications needs by building on your existing fundamental skills. You'll learn about advanced GD&T concepts like f ixed and floating fasteners, composite tolerancing, tolerance definition, datum selection and more key dimensioning topics and concepts of GD&T as prescribed in the ASME Y14.5M-1994 Standard.

Who should attend:

Representatives from design, quality, production and suppliers can attend this course.

Course Highlights

The workshop is based on a series of goals and objectives. It includes numerous practice problems and in-depth coverage of dimensioning and tolerancing. You will learn the application of GD&T in real world situation and how to reduce production cost by using the appropriates tolerances.

Course description: (2 days)

You will learn how to apply GD&T to a variety of situations. Improve your Geometric Tolerancing skills, get your questions answered. Also, this course will help you to create better designs, reduce drawing errors, increase productivity, increase part tolerances, assure that mating parts will assemble, improve inspection accuracy, etc.
