PROBLEM STATEMENT
Lathe is suitable for operations like turning, boring, facing taper turning, thread cutting, knurling, etc. but not suitable for operations like key way cutting etc. Because in a conventional lathe as soon as the machine is switched on, the workpiece fixed to the chuck rotates. This is a major limitation of the conventional lathe keeping in view of the present project work.
Gear cutting is a specialized form of milling, and the lathe is quite suited to this job for smaller work (6″ diameter or so) with the help of attachment.
 
OBJECTIVE
The objective of this project is:
  • Our project design and fabrication of gear cutting attachment is used to cut gear or splines over the cylindrical job.
  • Our main aim is to prove lathe as a versatile machine and with the help of gear cutting attachment the object is possible by lathe itself.
Cutting of a Spur Gear on a Milling Machine involves the following steps:
1.To determine the important dimensions and proportions of the gear tooth
element.
2.Mounting the cutter and the job on the machine.
3.Adjust the position of the table to the starting position.
4.Indexing.
5.Repeat the operation till the gear is complete.

 INDEXING

Indexing is an operation of dividing the periphery of a piece of work into any number of equal parts, for e.g. this operation can be adopted for producing hexagonal and square headed bolts, cutting spines on shafts, fluting drills and in gear cutting. All these works require a holding device which will permit the rotation of the work about the axis so that periphery of the work piece can be divided equally and accurately. Such a work holding devices is known as DIVIDING HEAD OR INDEXING HEAD.
ANALYSIS OF DESIGN
Final parts and final assembly is analyzed by solid works software. We use parameters of standard lathe machine and milling cutter for force analysis.The analysis was done on the basis of –
Static force
Maximum principal elastic strain
Maximum shear stress
Von Mises elastic strain
Von Mises stress
Factor of safety
