Metal matrix composites are relatively low-weight materials comprising of reinforcing elements in their structure which tend to improve the hardness, abrasion resistance as well as well as fatigue resistance of the material. One of the metal matrix composites with significant mechanical features are titanium metal matrix composites (Ti-MMCs) which can be considered as an alternative to nickel based superalloys in wide range of applications in numerous manufacturing sectors, including automotive, and aerospace. Despite significant features aforementioned, due to high manufacturing costs and presence of reinforcing elements in metal matrices, machining and machinability of Ti-MMCs is a complex subject. Knowing that limited studies are available on machining Ti-MMC under various lubrication modes and lubrication rates, adequate knowledge on the effects of cutting parameters and lubrication modes on machinability attributes of Ti-MMCs is a delicate subject. Therefore, the first aim of this work is to present the effects of cutting parameters, including lubrication modes and lubrication rate on machinability attributes, including surface quality. Furthermore, the Fast Fourier transform (FFT) will be used to evaluate the effects of cutting parameters on frequency domain of recorded cutting forces.
