The purpose of the experiment is to learn the use and the purpose of lathe machine. To use the lathe machine to cut a given metal cylinder to required diameter. Equipment:

* Metal Cylinder
The dimensions of the metal bars had length of 101mm and diameter of 25mm.

* Vernier Caliper
Vernier Caliper is a measuring instrument. It is used to measure the diameter or lengths and widths of objects up to 100th of a mm. I used it for measure of the length and width of the metal bar.

* Lathe Machine

A lathe is a machine tool which rotates the workpiece on its axis to perform various operations such as cutting, sanding, knurling, drilling, or deformation with tools that are applied to the workpiece to create an object which has symmetry about an axis of rotation. Lathes are used in woodturning, metalworking, metal spinning, and glassworking. Lathes can be used to shape pottery, the best-known design being the potter's wheel. Most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional solids of incredible complexity. The material can be held in place by either one or two centers, at least one of which can be moved horizontally to accommodate varying material lengths. Other workholding methods include clamping the work about the axis of rotation using a chuck or collet, or to a faceplate, using clamps or dogs.

Lathe machine Components
Bed: Usually made of cast iron. Provides a heavy rigid frame on which all the main components are mounted. Ways: Inner and outer guide rails that are precision machined parallel to assure accuracy of movement. Headlock: Mounted in a fixed position on the inner ways, usually at the left end. Using a chuck, it rotates the work. Gearbox: Inside the headstock, providing multiple speeds with a geometric ration by moving...
