Abstract. Interactions of wear debris at the toolworkpiece interface in microgrinding are quite random which leads to considerable variability in the working life of similar tools. It is not possible to capture the effect of wear debris entrapment on process signals using the available physicsbased model, which makes it difficult to identify the tool life stages. The present study ...
