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

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...

Process damping is a damping mechanism during the machining process that can be exploited to improve the limited productivity in machining titanium alloy at low cutting speed.
