What are the selection criteria for CNC turning?

Turning is to use the rotary motion of the workpiece and the linear or curvilinear motion of the tool to change the shape and size of the blank on the lathe, and process it to meet the requirements of the drawing. Turning is a method of cutting a workpiece on a lathe using the rotation of the workpiece relative to the tool. The cutting energy of turning is mainly provided by the workpiece rather than the tool. Turning is the most basic and common cutting method and plays a very important role in production. Turning is suitable for machining rotary surfaces. Most workpieces with rotary surfaces can be processed by turning methods, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end faces, grooves, threads, and rotary forming surfaces. The tools used are mainly turning tools. Among all kinds of metal cutting machine tools, lathes are the most widely used, accounting for about 50% of the total number of machine tools. The lathe can not only turn the workpiece with turning tools, but also use drills, reamers, taps and knurling tools for drilling, reaming, tapping and knurling. According to different process characteristics, layout forms and structural characteristics, lathes can be divided into horizontal lathes, floor lathes, vertical lathes, turret lathes and copy lathes, most of which are horizontal lathes. The principle of determining the turning processing route is to ensure the processing quality, and the tool path is the shortest.
