- Abstract
In the turning process, the slender shaft workpiece is one of the difficult parts. Especially the action of load on the surface of rotary workpiece and interaction between the workpiece vibration and cutting force increase the vibration of the workpiece and even cause flutter. Based on the theory of moving load, this paper has designed the concrete experiment, analyzed the cutting force in three directions, the surface vibration and roughness of the workpiece, the modal parameters of the workpiece and the tool, the self-power spectral density of the tool and so on. The change rule of six influencing factors with the change of feed rate also validates the correctness of the moving load theory. Through the analysis of the surface vibration and roughness of the workpiece, the degree of vibration of the workpiece increases and even the flutter phenomenon increases with the increase of the feed speed in a certain range. When the feed rate increases to a certain value, the degree of vibration of the workpiece has a tendency to weaken. The conclusion has certain guiding significance and application value to reduce the vibration and even flutter phenomenon, and provides a theoretical basis for applying the moving load theory to the complicated structure research on cutting vibration of shaft parts.
