Applied Application for Geometric Dimensioning and Tolerancing
Mechanical product designs often involve intricate components and sub-assemblies. A crucial aspect of designing and manufacturing products, particularly precision items, is the clear and accurate definition of geometric part functions. These geometric specifications, whether in electronic or paper-based engineering drawings, must be defined, interpreted, and communicated correctly in detail before production begins.
A good understanding of this process can significantly contribute to creating high-quality, functional engineering products, offering deeper insights into product performance, improving future design capabilities, and strengthening technical and economic competitiveness. Geometric Dimensioning & Tolerancing (GD&T) plays a fundamental role in achieving these objectives and is increasingly being adopted in engineering production drawings.
Key Benefits
This course aims to explore the Geometric Dimensioning & Tolerancing (GD&T) language, its associated symbols, concepts, and rules, as well as how to read, interpret, and apply them to enhance technical expertise and productivity. It will also cover various Geometric Dimensioning and Tolerancing (GD&T) standards in detail.
What you will learn and apply by the end of the course:
- To learn the basic principles and building blocks of Geometric Dimensioning and Tolerancing
- To appreciate the merits of Geometric Dimensioning and Tolerancing and how it complements conventional tolerancing methods
- To be able to read, specify and interpret Geometric Dimensioning and Tolerancing language
- To apply Geometric Dimensioning and Tolerancing for technical and economic competitive advantages
- To undertake a simple product design task that includes Geometric Dimensioning and Tolerancing specifications.
