Increasing the productivity of machining during vibration cutting

Difficult-to-process materials have been widely used in the details of rocket engines, aircraft and aerospace vehicles. Alloys containing titanium are difficult to process materials. They combine high hardness and low thermal conductivity, which leads to a deterioration in cutting performance. With traditional cutting, problems arise related to heating the cutting tool to a high temperature, vibration, and chip formation and removal from the cutting area. The use of vibration of the cutting tool during the machining process makes it possible to reduce the temperature in the cutting area and external vibrations, make it easier to remove chips and reduce its size, as well as increase the cutting depth. Vibration of the cutting tool makes it possible to reduce roughness, remove burrs, improve the accuracy of the resulting dimensions and the productivity of machining. The microstructure of the surface obtained using an interferometer at different values of the instrument rotation frequency is considered. The effect of vibrations on chip formation is shown.
