Modern automatic assembly puts forward higher requirements for the stability and accuracy of material conveying. In order to meet industrial needs, a piezoelectric vibration that uses a rectangular piezoelectric vibrator as an excitation source and works in a vertical drive mode was designed. Feeder. By simplifying the double⁃cantilever piezoelectric vibrating feeder and establishing its dynamic model, the expressions of natural frequency and device amplitude were derived, and some factors affecting natural frequency and amplitude were analyzed. Use ANSYS Workbench software to analyze the dynamics of the device. The natural frequency of the system was 118.85 Hz, and the harmonic response analysis of the device was performed. The results show that when the driving voltage is 200 V, the system driving frequency is between 116.00～122.00 Hz, and the double cantilever piezoelectric vibration gives The feeder has the ability to transport materials, the vibration amplitude is the largest at the point closest to the resonance point (118.00 Hz), and the transport efficiency is the highest, which can meet the requirements of industrial production.

GH4169 Nickel-based superalloys widely used, but it was difficult to cut.The residual stress of the machined surface could easily lead to the deformation of the workpiece, thereby the machining quality of the workpiece was affected.The variation of residual stress under different cutting parameters was studied by the simulation software Deform-3D. Simulation results showed that the change of cutting speed had little influence on the surface residual stress, the surface residual stress was increased with the increase of the cutting depth and the feed rate. The residual stress in workpiece was increased with the increased cutting parameters.

In the titanium alloy cutting operations with carbide tools, tool wear is one of the main restrictive factors on its tool life, and the cutting temperature significantly affects the tool wear, and closely related to work piece surface integrity and machining precision. Therefore, the analysis of temperature changes of cutting temperature and the tool wear are helpful to increase the productivity and lower down the costs of production. In this paper, the finite element software Deform3D was used to make simulation analysis on cutting temperature field and tool wear during the process of titanium alloy cutting operations with carbide tools. Accoordingly, the influence of the cutting speed, feed and cutting depth, and the dynamic changes of the rake angle of the tool on cutting temperature was achieved, and the change law of tool wear condition with cutting temperature. The findings of this research are helpful to optimize the cutting parameters and research the mechanism of tool wear.
