Effects of Irregular Tool Geometry and Machining Process Parameters on the Wavelength Performance of Process Damping in Machining Titanium Alloy at Low Cutting Speed

In machining titanium alloy as difficult-to-cut or hard materials, productivity is limited because of low heat conductivity at high spindle speed. Process damping is a damping mechanism during the machining process that can be exploited to improve the limited productivity in machining titanium alloy...
