All of the notes so far have referred to fits in cylindrical terms, ie holes and shafts.

This is by far the most common occurrence, but this system is also adaptable to fits between parallel surfaces, typically rectangular drive keys in rectangular slots. Choosing the correct fit The notes so far have explained the principles and representations of limits and fits.

The designer however is faced with the more fundamental task too of selecting the correct fit to use. This requires considerable experience, but some general guidelines should be noted. Refer back to table 2, which shows the preferred subset of ISO fits to choose from.

These have been divided into 3 categories of fit: Clearance Transitional Interference. Clearance fits are for use when there is movement in the form of running or sliding conditions between two mating parts.

The choice of which specific clearance fit to use depends mainly on the degree of precision necessary for effective functioning. Interference fits are used where there is a need to maintain a definite contact pressure between two stationary parts, so as to ensure no relative movement between them under all load conditions.

Showing Fit Dimensions on Drawings The information on a drawing has to satisfy the sometimes differing needs of all those who refer to it. Someone who is manufacturing a part needs to see the actual tolerance values, and should not be expected to ascertain these from a fit. Engineering drawing, most commonly referred to as engineering graphics , is the art of manipulation of designs of a variety of components, especially those related to engineering.

It primarily consists of sketching the actual component, for example a machine, with its exact dimensions.

The scale of dimensions is suitably adjusted so as to properly fit within the contours of the drawing sheet. The book provides all aspects and detailed study of Engineering Drawing — Plane and Solid Geometry , a core subject for all branches of Engineering study, presented in a lucid manner and easy-to-follow style.

The text book follows the first-angle method of orthographic projection, however, the third-angle projection method has not been completely ignored.

The entire book is printed in two colour which enhance the utility of the book. In this Fifty-third Edition some errors are rectified.

The earlier Fiftieth Edition of this text-book is thoroughly revised, extensively enlarged, completely updated. It has been one of the most comprehensive revisions since the book was first published.

As a result, all the drawings have been redrawn with utmost intelligibility. Many new examples, drawings are incorporated along with some new text matter.

This is achieved by defining the size and shape of a tolerance zone as opposed simply to a toleranced dimension within which the surface or median plane or axis of the feature is to lie. Some of the possible inaccuracies are listed below. This is by far the most common occurrence, but this system is also adaptable to fits between parallel surfaces, typically rectangular drive keys in rectangular slots.

Thus any pairing of holes and shafts whose diameters lie within the range given by these values are equally acceptable for achieving the class of fit, and hence functional performance, that is required.
