The first lathe machine that was ever developed was the two-person lathe machine which was designed by the Egyptians in about 1300 BC. Primarily‚ there are two things that are achieved in this lathe machine set-up. The first is the turning of the wood working piece manually by a rope and the second is the cutting of shapes in the wood by the use of a sharp tool. As civilizations progressed‚ there have been constant modifications and improvements over the original two-person lathe machine‚ most importantly

Lathe Machine Turning is one of the most common of metal cutting operations. In turning‚ a workpiece is rotated about its axis as single-point cutting tools are fed into it‚ shearing away unwanted material and creating the desired part. Turning can occur on both external and internal surfaces to produce an axially-symmetrical contoured part. Parts ranging from pocket watch components to large diameter marine propeller shafts can be turned on a lathe. The capacity of a lathe is expressed

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

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‚ facing‚ turning‚ with tools that are applied to the workpiece to create an object which has symmetry about an axis of rotation. Parts Headstock contains high-precision spinning bearings. Rotating within the bearings is a horizontal axle‚ with an axis parallel to the bed‚ called the spindle. The tail-stock contains a barrel

WEEKLY REPORT – LATHE MANUFACTURING LAB (MEFB 121) GROUP 3 REV NO : 000 DATE : 11 NOVEMBER 2011 2. PURPOSE The purpose of this activity are to verifies various type of lathe and their basic construction. Apart from that‚ it also make us to be familiar for cutting and turning process In lathe. 3. EQUIPMENT Less tool are required to perform lathe activity. This is due to lathe machine itself provide a lot of multifunction features that can obtain various desired outcome for a workpiece. 3.1) Vernier

A metal lathe or metalworking lathe is a large class of lathes designed for precisely machining relatively hard materials. They were originally designed to machine metals; however‚ with the advent of plastics and other materials‚ and with their inherent versatility‚ they are used in a wide range of applications‚ and a broad range of materials. In machining jargon‚ where the larger context is already understood‚ they are usually simply called lathes‚ or else referred to by more-specific subtype names

AUTOMATIC LATHE This is closely related to the centre lathe in some features but differs in the sense that they are machine tools in which the parts are machined automatically.The working process is fully automatic that is repeated to produce many parts without the direct involvement of the operator.Both the working and non-working are performed in a definite sequence by the control system adopted in the automatic which is set up to suit given project.In real sense‚no lathe machine is totally

CLASSIFICATION OF LATHES One of the most important machine tools in metal industry is the lathe. The main function of a lathe is to remove material from a workpiece so as to give it the required shape and size. A suitable classification of lathe machines is difficult due to many variations available in their size‚ design‚ methods of drive and applications. The generally used classification of the lathe is as follows: • Speed Lathe This is simplest of all types of lathes. It consists of a bed

The Centre Lathe The Centre Lathe is used to manufacture cylindrical shapes from a range of materials including‚ steels and plastics. Many of the components that go together to make an engine work have been manufactured using lathes. These may be lathes operated directly by people or computer controlled lathes that have been programmed to carry out a particular task. A basic manual centre lathe is shown below. This type of lathe is controlled by a person turning the various handles on the top slide
