Observation of a unique wear morphology of cBN inserts during machining of titanium metal matrix composites (Ti-MMCs); leading to new insights into their machinability

Titanium-based metal matrix composite (T-MMC) is a relatively new material with increasing demand in different industries particularly in aerospace. Yet, there is a significant lack of knowledge regarding its machinability. Tool wear mechanisms of cBN inserts during turning of TiMMCs including adhesion, abrasion, chemical interactions, and their effects on the wear surface morphology were investigated. A unique wear morphology was observed on …
