Among them, the main influencing factors of machining accuracy, the main machining methods and the interaction between controllable factors in production are more important. During CNC turning milling compound machining, the tool performs intermittent cutting, and the workpiece formed by any material can be cut in a relatively short time, which is easy to remove chips actively. Moreover, intermittent cutting can make the tool have sufficient time to cool, reduce the thermal deformation of the workpiece, and improve the service life of the tool. Compared with traditional CNC machine tools, CNC turning and milling machining has higher speed, better cutting product quality, reduced cutting force, improved the accuracy of thin-walled bars and slender bars, and high workpiece forming quality.
When the CNC turning milling machine tool processes the workpiece, the low rotation speed of the workpiece can effectively reduce the centrifugal force of the workpiece, avoid the deformation of the workpiece, and improve the machining accuracy of the parts. The use of large longitudinal feed in CNC turning and milling composite processing can also get accurate cutting, and the surface roughness can also be useful to ensure that CNC turning and milling composite processing machine tools can use different methods such as turning, milling, drilling, boring to complete the processing of workpieces, and workpieces can also be clamped at one time to complete the multi-faceted processing mission, so as to ensure the processing accuracy.
