1. Improve cutting speed

In the cutting process, if the cutting speed is too low, the workpiece will produce chip buildup in the cutting process, which will affect the surface quality of the workpiece. Because the cutting speed is inversely proportional to the degree of plastic deformation, higher cutting speed can greatly reduce the plastic deformation of the workpiece surface and effectively reduce the roughness of the workpiece surface.

2. Improve the accuracy of machining equipment

The error of CNC machine tool will directly affect the accuracy of the workpiece. The accuracy of CNC machine tool can effectively reduce the error in the process of processing. Fixture and tool error will also affect the accuracy of the workpiece, so take measures to reduce wear, can improve the accuracy of the workpiece, improve the quality of the workpiece.

3. Improve the cutting level

In the cutting process, the surface of the workpiece will form the impression similar to the tool shape, leaving a large number of scales, which is easy to increase the surface roughness and reduce the quality of the workpiece. In this case, the radius of the tool tip should be increased and the tool feed should be reduced, so that the height of the residual area of the tool on the workpiece can be reduced as much as possible, and the surface roughness of the workpiece can be controlled in a reasonable range. It can effectively reduce the chip and scale on the surface of the workpiece, improve the surface quality of the workpiece and prolong the service life of the workpiece.
