The name and important particulars of a customer are indexed. If (n — N) is positive, the index plate will rotate in the direction in which crank is rotated and if (n — N) is negative, it will rotate in opposite direction to that of crank. Knight (1979, 17) wrote that the Latin word had the meaning “he who, or that which, points the way”. 8. This system is highly suitable to small concerns and not suitable to large organization. Furthermore, as the data sets are real-time multimedia, they are rather large. Large number of cards may be maintained under this method.

Additions or deletion of entries on the card takes much time. During the differential indexing, the index-plate is unlocked and connected to a train of gears which receive their motion from the worm gear spindle. For example, if one wants to know the debts due to him by a customer named Sankar, refer the page number allotted to Sankar by seeing the name of the customer (i.e. Most importantly, in both the methods, the indexing should be controlled … In this method, the huge range for the columns is selected initially so that the mapping size of the first level becomes small. This method of index is suitable to small and medium size business office. The accuracy of spacing of teeth is very important particularly when the work is of precision character e.g., gear teeth, shafts, cutter teeth etc. Asynchronous methods. There is a high possibility of loss of cards, mutilation, or destruction. Sometimes it is necessary to introduce change gears between the worm shaft and the table feed screw, because when the table travels a distance equal to the lead of helix, the job must have completed one revolution.

This is an improved system of book index. For example, if a 27 teeth gear is to be cut, then T = 40/27 i.e., the rotation required for one tooth spacing is 40/27 which may be written as 2/3 + 22/27 or 12/18 + 22/27.

These loose indices are kept in a drawer. The following relation is used for simple indexing: T = 40/N, where T gives the number of turns or parts of a turn through which the index crank must be rotated to obtain the required number of divisions (N) on the job periphery. Using the axes of a coordinate system defined on the cells of a polyhedron is also another common method, that we call axes-based indexing. The ratio of crank and the shaft on which job is mounted is 40 : 1, i.e., when the index plate makes 40 revolutions, the job makes one revolution. Hence, addition of a new name under the same letter is very difficult. Indexing may be classified into the following main categories, namely: (a) Page Index; (b) Card Index and (c) Visible Index. So for each tooth, the worm will be rotated by 12 holes of 18 hole circle with the help of the crank and then the index plate is rotated by 22 holes of the 27 hole circle. This is accomplished with the help of a milling attachment known as dividing head, which is an accessory to the milling machine. Additional information can be included without much difficulty. It is a multilevel index format technique which is balanced binary search trees. 5.

To maintain the names, communication addresses and phone numbers of the customers. 6. Methods of indexing 1. To rotate a job through required angle, one needs: (ii) A source which can ensure that the job has been rotated through the desired angle. If it is desired to index a job by 35 degree, then the index head movement required to perform the operation will be = (35/9) = 3(8/9) = 3 + ((8 X 3) / (9 X 3)) = 3 + (24/27), i.e., the crank must be turned three complete revolutions plus 24 holes in the 27-holes circle. It is very easy to maintain the index. Additional information can be easily written on the cards without disturbing other cards. The card index can be utilized to serve the following purposes. The space is available and required for maintain index. i.e., the worm is to be rotated by the handle through one complete rotation and two-third of the number of holes of any circle. Before uploading and sharing your knowledge on this site, please read the following pages: 1. Hence, strip index has been designed to meet the above mentioned purpose.
