... improvement. The majority of tool wear model is based on cutting condition variations. However, several tool paths with the same cutting conditions lead to different tool lives. The impact of the cutting strategy is significant on tool wear and complex to anticipate. In this article, a global method allowing...

... decreased, which provided minor surface roughness with higher speeds. On the contrary, by increasing the speeds to levels that are more than 36,000 rpm, the machining process will produce a high level of vibrations that cause rapid tool wearing. This will keep increasing with higher spindle speeds...
