Objectives
Translating Designer’s thought into proper GD&T drawings, including tolerance allocations. You will learn the advanced concepts in GD&T, including:
- Tolerancing Mating Parts – learn-while-during training session.
- Direct Versus Indirect Datum Structures.
- Allowed versus Actual Deviation from True Position Bonus Tolerancing and Virtual Condition Boundaries.
- Profile, Flexible Parts and Datum Targets.
- Tolerancing Complex Assemblies with Multi-Level Functional Controls and Varying Datum Structures.
- Measuring and gauging GD&T, first article inspection, applying CMM to GD&T, and tabulation of results.
Duration
3 days | 9am – 5pm | 21 hours
Who Should Attend
This course is designed for designed for engineers who need to qualify parts with GD&T specifications. You will learn effective ways to measure and gauge geometric tolerances. You will also learn to select the most appropriate measurement techniques for particular GD&T specifications, whether it is prototype or production, batch production or mass production. Enhance understanding by using videos, with step by step explanations, using open setup, gauges or specialised equipment. Course Pre requisites Participants must possess basic knowledge of GD&T and Tolerance Analysis concepts.
Methodology
Participants will learn final details in advanced GD&T. Case studies and hands-on exercises using specially selected drawings allow participants to use and apply the information learnt in the course. Participants may also bring company drawings for interpretation during live case studies.
