Improving the Surface of Titanium Alloys with Wave Cutters

The article is devoted to the consideration of issues on improving the surface of titanium alloys using breakwaters. It is shown in the work that the processing of the titanium alloy used is a rather difficult task, since work in an aggressive environment imposes strict requirements on materials, namely: no reaction to external influences without loss of specified properties (solutions of diethanolamine, hydrogen sulfide), as well as a high specific strength, non-magnetic. The work investigates wave-shaped end mills made of high-speed steel for machining titanium alloys. The problem of calculating the geometry of wavy cutters is considered. It was established, on the basis of testing and measuring the vibration activity of the Part - Tool - Device - Machine tool (PTDM) system, that the roughness of the machined surface of the titanium alloy is less in wavy cutters compared to standard cutters made according to GOST 23,248–78. The stronger the titanium alloy, the less roughness when machining with wave cutter.
