In turning, milling, drilling and boring machine processing, as a qualified technician, you should be familiar with the processing principles, cutting parameters and calculation formulas. Only with good basic knowledge can the processing performance of CNC machine tools and cutting tools be fully utilized. Many factory technicians use cutting parameters purely based on their feelings, and they even think that these calculation formulas are useless. In fact, it's not that formulas are useless, it's that you don't understand them at all!
01 Turning definition and formula
Turning is an application that uses single-edged tools to machine bodies of revolution and curved surfaces of revolution. In most cases, the tool is fixed in feed motion and the workpiece rotates as the main motion.
