Cutting mechanism of straight-tooth milling process of titanium alloy TC21 based on simulation and experiment.

Due to the characteristics of high strength, high chemical activity and low heat conduction, titanium alloy materials are generally difficult to machine. As a typical titanium alloy with higher strength and lower heat conductivity, the machinability of titanium alloy TC21 is very poor and its cuttin...
