Introduction
Course Description:
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.
Course 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.
