Methods to improve the quality of machined workpieces:
1. Improve machining level
In machining, when the workpiece is cutting, the surface of the workpiece will form almost the same impression as the tool shape and leave a large number of scales and thorns, which is easy to increase the roughness of the workpiece surface and reduce the quality of the workpiece surface. Generally speaking, in this case, when cutting, it is necessary to appropriately increase the tip arc radius of the tool, appropriately reduce the feed amount of the tool, and minimize the height of the residual area of the tool on the workpiece, so as to ensure that the roughness of the workpiece surface is controlled within an appropriate range. This can effectively reduce the scale and burr on the workpiece surface, improve the quality of the workpiece surface and prolong the service life of the workpiece.

2. Improve cutting speed
When cutting the workpiece, if the cutting speed is high, the plastic deformation of the workpiece surface can be greatly reduced in the cutting process. The higher the cutting speed is, the smaller the degree of plastic deformation is, which can effectively reduce the roughness of the workpiece surface. If the cutting speed is not enough, the workpiece will produce chip nodules in the cutting process, which will affect the surface quality of the workpiece.

3. Improve the accuracy of machining equipment
The machining of workpiece is mainly completed by machine tool, and the error of machine tool itself will directly affect the accuracy of workpiece. This needs to ensure the accuracy of the machine tool itself, which can effectively reduce the error in the processing process. The error between the tool and fixture will also affect the accuracy of the workpiece. Corresponding measures can be taken to reduce the wear of the tool, which can improve the accuracy of the workpiece and improve the quality of the workpiece.
