Experimental study in high speed milling of titanium alloy TC21

In this paper, a number of experiments were carried out to study the machinability of a new damage-tolerant titanium alloy (TC21). Firstly, the effects of milling parameters, tool material, and tool wear on cutting forces were investigated. Secondly, the effects of milling parameters and tool wear on cutting temperature were studied. Finally, the effect of tool material on tool life was explored. Results showed that cutting force, cutting temperature, and tool life were greatly influenced by milling parameters, tool material, and tool wear. Thus, cutting tool matching with proper milling parameters should be carefully chosen to satisfying the tool life in actual production.
