Conference Paper

Tool life is a major cost driver in all micro milling operations, due to the costly and brittle nature of micro end mills. As such, the need exists to be able to predict tool life for the purpose of tool cost estimation. This paper addresses this issue by developing an empirically determined tool life model that characterises tool life in terms of cutting parameters. The model is intended for a specific application; that is, the micro milling of bipolar plates. Further, the model is developed via designed experimentation and multiple-linear regression analysis of the resulting data.
