the blank. Indexing mechanism requires skills and are time consuming. The improper indexing will lead to rejection of the job. So to overcome these limitations, a new automated digital indexing mechanism had been developed and to validate the movement, a dial gauge is fixed as the attachment in the traditional milling machine.

Mar 31, 2020 Indexing Mechanism is mainly used to cut gear teeth accurately. This mechanism is used for equal spacing of the teeth of the gear. This mechanism is also used for machining flutes of a milling cutter, milling curved slots and drilling a bolt hole circle around the circumference of a part.

Meaning of Indexing: Milling operations sometimes, require the rotation of job correct to fractions of minutes, for each groove, slot etc., to be cut evenly on the job surface. 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.

2. Indexing number is calculated to the position of the blank. 3. Gear blank is mounted on mandrel in milling machine. 4. Centering of the blank is done by upward and cross feed. 5. The depth of the cut is calculated for the given module. Result: Thus the gear cutting is performed in a milling machine.

Indexing in Milling. Indexing is an operation of dividing a periphery of a cylindrical workpiece into equal number of divisions by the help of index crank and index plate. Because the operator of the machine may want to rotate the part to an arbitrary angle indexing plates are used to ensure the part is accurately positioned.. Indexing in Milling Machine

Plain milling cutters that are more than 3/4 inch in width are usually made with spiral or helical teeth. A plain spiral-tooth milling cutter produces a better and smoother finish and requires less power to operate. A plain helical-tooth milling cutter is especially desirable when milling an uneven surface or one with holes in it. Types of Teeth
