Outlook on measurement, uncertainty and mathematical representation of the physical phenomena that occur in machining processes

In this article an outlook is given of our and other recent approaches of research and representation of the mathematical models of some physical phenomena that occur in the cutting process. The focus is on the mathematical power model reliability which can be evaluated by the uncertainty parameters based on all error contributors and presented along with the model. An algorithm is proposed for the recommended steps during experimental modelling of the cutting process and uncertainty estimation. The significance of certain errors sources from the measurement software, hardware and the cutting process itself is stressed
