An indexing head, also known as a dividing head or spiral head, is a specialized tool that allows a workpiece to be circularly indexed; that is, easily and precisely rotated to preset angles or circular divisions.Indexing heads are usually used on the tables of milling machines, but may be used on many other machine tools including drill presses, grinders, and boring machines.
6) Indexing head attachment 5.11 Indexing head Indexing is the method of dividing the periphery of a piece of work into any number of equal parts. The attachment used for performing indexing is known as indexing head. The indexing operation can be adapted for cutting gears, ratchet wheels, keyways, fluted drills, taps and reamers.

DCM selects cutting conditions and generates tool paths dynamically to satisfy instructed surface roughness [9,10]. METHODOLOGY In general, for job shop production, horizontal milling machine are used for the gear cutting operations and the indexing mechanism is essential for the deciding the number of teeth on the blank.
The operation of rotating the job through a required angle between two successive cuts is termed as indexing. This is accomplished with the help of a milling attachment known as dividing head, which is an accessory to the milling machine. It helps to divide the job periphery into a number of equal divisions, i.e., square, hexagonal octagonal, etc.
Milling machines are widely used in the tool and die making industry and are commonly used in the manufacturing industry for the production of a wide range of components as shown in figure 11. Typical examples are the milling of flat surface, indexing, gear cutting, as well as the cutting of slots and key-ways. 5. Milling Processes
