Abstract: The work here presented is framed in the line of development manufacturing processes for a new generation of slight materials with good mechanical properties, the Gamma TiAl alloys. These alloys were developed to achieve a reduction of weight in different components for aviation and automotion where very high temperatures are the main factor. In this application fields, several components must withstand high temperatures maintaining a high resistance. The superalloys of type Gamma TiAl are an attractive alternative to nickel-based alloys, due to the high ratio between resistance and weight and resistance and low corrosion. This work presents the results from milling tests on three types of Gamma TiAl alloys. End-milling tools made of integral hard metal were used, applying different feeds and cutting speeds. The influence of cutting speed and feed is discussed.
