Optimization Analysis of Turning Process Parameters for Shaft Characteristics

In the research that I did with the research team, using conventional machines that are widely used in a university. The machine we use is a conventional lathe with type Kinwa CH-530 � 1100. This study, we use several variables as a test of the material we use. The process of making a round shaft is very helpful in the machining process, because the spindle is very well rounded and the friction is small. Roundness values are obtained by using values from other geometric errors, namely alignment, perpendicularity, and geometric tolerance. From the results tested using this conventional lathe, it is still able to make precise components in terms of geometry. The geometric error value is still below the tolerance value of 50 m
