Abstract: Titanium metal matrix composite (Ti-MMC) has excellent features and capabilities which can be considered a potential candidate to replace commercial titanium and superalloys within an extensive range of products and industrial sectors. Regardless of the superior features in Ti-MMC, however, referring to several factors including high unit cost and existence of rigid and abrasive ceramic particles in the generated matrices of the work part, the Ti-MMC is grouped as extremely difficult to cut with a poor level of machinability. Furthermore, adequate process parameters for machining Ti-MMCs under several lubrication methods are rarely studied. Therefore, adequate knowledge of this regard is strongly demanded. Among machinability attributes, ultrafine particles (UFPs) and fine particles (FPs) have been selected as the main machinability attributes and the factors leading to minimized emission have been studied. According to experimental observations, despite the type of coating used, the use of higher levels of flow rate led to less UFPs, while no significant effects were observed on UFPs. Under similar cutting conditions, higher levels of FPs were recorded under the use of uncoated inserts. Moreover, cutting speed had no significant influence on UFPs; nevertheless, it significantly affects the FPs despite the type of insert used.
