To manufacture an engineering component, we need to prepare the manufacturing drawing with assigning tolerances, which includes controlling of size, shape and surface texture. Understanding of Limits, fits and Tolerance will control the size limit, GD&T controls the shape and study of surface roughness will help to choose the right machining.

Engineering design and Engineering drawing are incomplete without assigning tolerances. Tolerancing is an important and essential element in product manufacturing for both functional and interchangeability.

Understand the role of GD&T in reduction of manufacturing cost and lead time as well as enhanced product reliability. Thorough knowledge in GD&T – the essential link, connecting the functional departments in the manufacturing industry – is a must for engineers.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) is organizing a 5-day Hands-on training on “Interpretation of Manufacturing Drawing and Measurements”.
