<![CDATA[The manufacturing process is a process carried out to produce physical or chemical changes in raw materials. The manufacturing process is carried out in several steps starting from raw materials to the machining process. The machining process is a series of workpiece forming processes using cutting tools by cutting layers of material into the desired shape. This study aims to analyze the effect of cutting speed on lathe tool wear on SKD11 steel. This study uses an experimental method, using the transverse turning method. Transverse turning is a turning process when the cutting tool movement is parallel or linear with the spindle axis. The test specimens will be turned starting with determining the turning parameters, namely the feeding motion (f) 0.16 mm / rev, depth of cut (depth of cut) 1.0 mm, with variations in cutting length (Lt) 200 mm, 400 mm and 600 mm. then varying the cutting speed (Vc) starting from 99m/min, 172 m/min and 292 m/min. Based on the results of the test data obtained, it shows that; Cutting speed (Vc) affects the wear of the lathe tool blade on SKD11 material. The higher the cutting speed (Vc), the more the tool blade wear value (VB) increases.This is due to heat and friction between the cutting edge and the test piece. The wear that occurs on the lathe tool blade is edge wear or abrasive wear due to the continuous contact of the two materials so that it rubs between the lathe tool blade and the SKD11 material and is also caused by the thixotropy phenomenon.]]>
