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 caliper We used vernier caliper to measure the size of the object .Beside that ,it can be used to measure the length of the object, which specific size is 100mm and 25mm in diameter. 3.2) 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.

Below are the list of parts and functions in lathe machine. No 1 Components Bed Functions Provides a heavy rigid frame on which all the main components are mounted. Inner and outer guide rails that are precision machined parallel to assure accuracy of movement. mounted in a fixed position on the inner ways, usually at the left end. Using a chuck, it rotates the work. inside the headstock, providing multiple speeds with a geometric ratio by moving levers. Hole through the headstock to which bar stock can be fed, which allows shafts that are up to 2 times the length between lathe centers to be worked on one end at a time to clamp part being machined and allows the mounting of difficult workpieces that are not round, square or triangular. Fits on the inner ways of the bed and can slide towards any position the headstock to fit the length of the work piece. An optional taper turning attachment would be mounted to it. Moves on the outer ways. Used for mounting and moving most the cutting tools Mounted on the traverse slide of the carriage, and uses a hand wheel to feed tools into the workpiece. To mount tool holders in which the cutting bits are clamped Mounted to the cross slide, it pivots around the tool post Attached to the front of the carriage, it has the mechanism and controls for moving the carriage and cross slide. For cutting threads

4. PROCEDURE Procedure for this purpose can be classified into 3 different topics; Work procedure, Operation and Safety precautions which each of those carried elements of different perspective but act under the same objective. 4.1. Work Procedure I. Morning briefing by the technician; Mr. Shamsul on all aspect of job scope II. Proper safety attire were wore first III. Our group were given one workpiece for this particular activity. Using vernier calliper, the dimensions...
