Geometric Dimensioning & Tolerancing (PDU)(SF Series) 


Today, engineering drawings are used to define or describe most manufactured parts. In each of these parts, tolerances are specified to cater for the variations encountered in the manufacturing process. This is to ensure that acceptable levels of variation and quality for each geometric feature can be achieved when parts are assembled together to form an engineering product. As mechanical designs can be complex involving numerous parts and sub-assemblies, increasingly more firms are required to specify and interpret Geometric Dimensioning & Tolerancing (GD&T) symbols on these drawings so that better clarity and acceptance rates can be achieved. This course seeks to look at the GD&T language and its related symbols, its concepts and rules as well as to read, interpret and specify them so that greater technical and productivity can be achieved. 


1. To learn the basic principles and building blocks of GD&T
2. To appreciate the merits of GD&T and how it complements conventional tolerancing methods
3. To be able to read, specify and interpret GD&T language
4. To apply GD&T for technical and economic competitive advantages

Underpinning Knowledge:
1. To know the definitions, concepts and rules of the GD&T language and its related symbols.
2. To read, interpret and specify the various GD&T symbols in the engineering drawings
3. To be exposed to the various gauging tools and techniques used to determine the intended geometric characteristic features.
