What's the difference between NC machining method and traditional machining method?

CNC machine tools have a great feature, and some processing methods need to be used carefully when processing some traditional machine tools, which makes them usable. In traditional machining, the cantilever boring and the supporting boring formed by tailstock guidance are replaced by turning boring and different forms of fixed circulation in CNC machine tools. Traditional machining methods, such as blank cutting, filling, trimming and their processes, have been replaced by various forms of back boring, arc interpolation and CNC trimming. At present, as a new machining technology, hard cutting can not only improve work efficiency, but also greatly reduce costs, which makes the traditional grinding process face new challenges. Cutting instead of grinding will be the development trend of modern manufacturing and processing. Compared with wet cutting, dry cutting, as a green manufacturing process, also has many advantages, but there are still shortcomings. The tool has low durability, increased cutting force and serious deformation, which can not guarantee the machining quality of the workpiece. However, by analyzing the influencing factors and characteristics in dry cutting, the remedial measures are found, and the advantages of this cutting method are still relatively large.
