No part of this publication may be reproduced in any form or by any means graphic, electronic or mechanical, including photocopying, recording, taping or information storage and retrieval systems - without the prior permission in writing of the publishers. It also covers the syllabus for Engineer Cadet courses in the subject. The text is intended to cover the ground work required for the examinations. The syllabus and principles involved are virtually the same for all examinations but questions set in the Class One require the most detailed answer. The book is not to be considered as a close detail reference work but rather as a specific examination guide, in particular most of the sketches are intended as direct applications to the examination requirements. If further knowledge from an interest aspect is required the student. The best method of study is to read carefully through each chapter, practising sketchwork, and when the principles have been mastered to attempt the few examples at the end of each chapter. Finally, the miscellaneous questions at the end of the book should be worked through. The best preparation for any examinations is the work on examples, this is difficult in the subject of Engineering Knowledge as no model answer is available, nor indeed any one text book to cover all the possible questions. As a guide it is suggested that the student finds his information first and then attempts each question in the book in turn, basing his answer on a good descriptive sketch and writing occupying about one side of A4 in 20 minutes. In order to keep as closely abreast as possible to the latest DTp examination questions the book has been extensively revised. The Department of Transport publish examination question papers and have given permission to reproduce questions from them.

Specifically, planned maintenance is a scheduled service visit carried out by a competent and suitable agent, to ensure that an item of equipment is operating correctly and to therefore avoid any unscheduled breakdown and downtime.

Planned maintenance is preplanned, and can be date-based, based on equipment running hours, or on distance travelled. Parts that have scheduled maintenance at fixed intervals, usually due to wearout or a fixed shelf life , are sometimes known as time-change interval, or TCI items. Predictive replacement[ edit ] Predictive replacement is the replacement of an item that is still functioning properly.

These items are given to tax-exempt institutions. Albeit chronologically much older, It is considered one section or practice inside the broader and newer predictive maintenance field, where new AI technologies and connectivity abilities are put to action and where the acronym CBM is more often used to describe 'condition Based Monitoring' rather than the maintenance itself.

CBM maintenance is performed after one or more indicators show that equipment is going to fail or that equipment performance is deteriorating. This concept is applicable to mission-critical systems that incorporate active redundancy and fault reporting. It is also applicable to non-mission critical systems that lack redundancy and fault reporting. Condition-based maintenance was introduced to try to maintain the correct equipment at the right time.

CBM is based on using real-time data to prioritize and optimize maintenance resources. Observing the state of the system is known as condition monitoring. Such a system will determine the equipment's health, and act only when maintenance is actually necessary. This completely new structure which has been brought about by heating and then rapidly cooling the steel is called 'Martensite', a hard needle like structure consisting of iron supersaturated with carbon, and is basically responsible for hardening steels.

If a steel of approximately 0. In this condition the steel would be fully hardened i. Choosing a temperature lower than the above but not lower than C lower critical and then quenching, will produce a partly hardened steel having a Brine11 numeral between 2, to 6, Hardening material in this way produces internal stresses and also makes the material brittle. To relieve the stresses and restore ductility without loss of hardness or toughness, the material is tempered.

Tempering consists of heating the material to about C, retaining this temperature for a duration of time this depends upon the mass and the degree of toughness required and then quenching or cooling in air. The combination of hardening and tempering is greatly employed with steels and alloy steels, a wide range of properties is available thereby.

Components such as drills, chisels, punches, saws, reamers and other tools are invariably subjected to the above process.

Straight carbon steels whose carbon content is below 0.

The reason could be attributed to the smaller quantity of Martensite which would be produced. The object of annealing is either to grain refine, induce ductility, stress relieve or a combination of these. Castings, forgings, sheets, wires, and welded materials can be subjected to an annealing process.

This process consists of heating the material to a pre-determined temperature, possibly allowing it to soak at this temperature, then cooling it in the furnace at a controlled rate.

For full annealing and normalising, the temperature for carbon steels is usually 30" to 40C above the upper critical temperature.

Essentially, the difference between full annealing and normalising is that in the case of the annealing process the material is cooled slowly in the furnace whereas for normalising the material is cooled in still air out of the furnace.

These processes of full annealing and normalising are mainly used on castings since they will usually have a variation in size and shape of grain. The casting is heated to about 40C above the upper critical temperature and held at this temperature until it is uniform in temperature throughout.
