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 cutting tool was aligned to the dead center. The machine was turned on. The carriage was moved to the left by rotating the hand wheel until the tip of the cutting tool touches the edge of the metal cylinder.

For safety reason, the workpiece were mounted with 0.5mm per run(safe operation). The machine then were run by cutting the whole workpiece for 20mm diamater. This process need to be done two times which one on the left hand side and the right hand side. The carriage need to be push to the left slowly. For 20mm diameter cut,we need to repeat 4 times because to follow the safe operation procedure. Step 6 below were repeated for cutting the 15mm and 10 mm diameter. The final workpiece is as per below:

Ø15

Ø20

Figure 4- the final workpiece. 4.3. Operation I. II. To perform lathe activity, the workpiece need to be lock and secure in the spindle at first. Then the lever that control the x-axis of the lathe machine is adjust and set to 0. This step is essential so that the operator keep tracks of the depth between the initial and the final workpiece. For safety purporse, the lathe machine only can cut down the workpiece for 0.5mm per run. Apart from that,coolant switch also are turned on to reduce the friction between the cutter n workpiece. After all, the main
