21 " Broaching is a precise machining process in metalworking domain which uses a toothed tool called broach to cut materials into a predetermined shape. Broaching works best for odd shapes where precision machining is needed and hence finds wide application in a number of industry in India and worldwide. Broach resembles a saw to certain extent but unlike a saw, its teeth become larger in size across its length. A broach gives shapes by roughing or removing the material, semi finishing and then by imparting the ultimate finishing. Round or odd shapes, for both internal and external surfaces, can be conveniently formed by broaching. This multi edge tool can shape any metal or metallic alloy but works best on softer materials like plastic, wood, bronze, aluminum, etc. Resharpening of the tool The broach that imparts shape to many work pieces can work properly only when the size and shape of its teeth are perfect. With time and usage, the teeth tend to lose its sharpness and become blunt. Using a dull broach may lead to permanent damage of its teeth. To enhance the broach life and minimize the tooling expense, it needs to be re-sharpened on time. When to opt for resharpeningWhen broaching produce roughly shaped work pieces, it is definitely time for re-sharpening. However, with a little bit of watchfulness, one can even get it sharpened before it delivers poor finish or tearing. Some of the other conditions when this toothed tool will require re-sharpening are:• Excessive hydraulic press pressure required to run the broach• Nicks and scratches on the teeth making it dull • Broach starts drifting• Cutting edges show signs of wear • Chattering occurs while broaching Re-sharpening requires high precision. Removing excessive material from the teeth will adversely affect its longevity. Only proper sharpening will ensure time efficiency and high quality output. Teeth welding, grinding of gullets and teeth crest, reshaping teeth to proper taper are some of the methods used in re-sharpening.Broaching, once used for machining only internal keyways, is now used for machining a plethora of shapes and surfaces for high quantity of work pieces. Broaching requires less tools than most of the other machining process and saves considerable amount of output time and hence favoured for high volume production irrespective of its high cost. In India, broaching finds wide application in the automobile industry. Therefore, a large number of players are foraying into the broach manufacturing industry on a regular basis. "

22 " For a man who was to exhibit such acute political sharpness later in his career, Napoleon completely misread the revolution's opening stages. 'I repeat what I have said to you,' he wrote to Joseph on July 22, a week after the fall of the Bastille, 'calm will return. In a month, there will no longer be a question of anything. So, if you send me 300 livres [7,500 francs] I will go to Paris to terminate our business. "

23 " Like Pascal, Nietzsche, and Simone Weil, Kierkegaard is one of those writers whom it is very difficult to estimate justly. When one reads them for the first time, one is bowled over by their originality . . . and by the sharpness of their insights. . . . But with successive readings one’s doubts grow, one begins to react against their overemphasis on one aspect of the truth at the expense of all the others, and one’s first enthusiasm may all too easily turn to an equally exaggerated aversion. Of all such writers, one might say that one cannot imagine them as children. The more we read them, the more we become aware that something has gone badly wrong with their affective life; . . . it is not only impossible to imagine one of them as a happy husband or wife, it is impossible to imagine their having a single intimate friend to whom they could open their hearts.
