Cylindrical Turning Techniques and Tools

This video tutorial explains the technique of pembubutan rata, which involves reducing the diameter of a workpiece by cutting its side surface. The instructor outlines the necessary tools, including the workpiece, cutting tool, and cooling liquid. The video demonstrates the setup of the machine and the process of performing pembubutan rata, emphasizing the importance of correct machine rotation and tool positioning. The tutorial concludes with measuring the workpiece's diameter to ensure it meets the desired specifications.
