Abstract

Lathe is the process of working on materials where the workpiece and the tool chisel move horizontally (in the direction of the table / bed machine), transversely or form angles slowly and regularly either automatically or manually. In the turning process takes place, the workpiece rotates and the chisel is touched on the workpiece so that the cut occurs. The incision can be carried out towards the left or right, so as to produce a cylindrical workpiece. If the cutting is done transversely it will produce a form of grooves, cuts or surfaces called faces. Besides being able to be used for turning, the lathe can also be used for the propeller shaft centering process at the shipyard when the ship is docking. Centering shaft propeller aims to check the straightness of the propeller shaft on a ship on a lathe by turning it manually using human power, if there is a change in the shape of the deflection can be straightened on the lathe using a lathe. The research method used is qualitative and quantitative. From the results of the propeller shaft research can still be used because the deflection is not more than 1.0 mm, if more than that value is immediately replaced by the propeller shaft. Keywords: Lathe, Shaft Propeller, Centering
