This paper suggests a methodology to study the tribology of the titanium alloy TI6Al4V with different coated CW pins. A huge range of pin-on-disc tests were run to establish an accurate method to obtained useful information about friction phenomenon to be considered in forming processes as Single Point Incremental Forming and in the Machining of titanium alloys whereas this friction system is acting in. Combining diverse parameters as sliding speed, normal force and sliding length it is possible to evaluate the evolution of the friction coefficient and the tool wear under different lubricant conditions. In all cases, large length tests allowed more suitable results than short length ones to analyze the tribological behavior of the different tested pairs. Post-test study of the pin surface was developed in order to evaluate the material transfer and the tool wear. In this way, it was possible to link the friction coefficient whit bare CW pins. The use of a lubricant fluid increases the friction coefficient value while reduces the tool wear.
