Assessment of Commonly used Tool Life Models in Metal Cutting

Johansson, Daniel LU ; Hägglund, Sören; Bushlya, Volodymyr LU and Ståhl, Jan Eric LU (2017) In Procedia Manufacturing 11. p.602-609
Abstract

In this work, eleven different combinations of work piece materials and tool grades have been evaluated in wear test when turning with cemented carbide insert. The most commonly used tool life models such as the Taylor model, the Extended Taylor model, the Coromant Turning model version 1 and the Colding model have been tested on the data and their accuracy is presented. The well-known Taylor model proves to have a limited ability to reproduce the data. The most accurate model is the Colding model, with an average model error of approximately 4.0% and Woxén equivalent chip thickness proves to work well for all presented tool life models. This work also discusses the models ability to reproduce cutting data for finishing operations and... (More)

In this work, eleven different combinations of work piece materials and tool grades have been evaluated in wear test when turning with cemented carbide insert. The most commonly used tool life models such as the Taylor model, the Extended Taylor model, the Coromant Turning model version 1 and the Colding model have been tested on the data and their accuracy is presented. The well-known Taylor model proves to have a limited ability to reproduce the data. The most accurate model is the Colding model, with an average model error of approximately 4.0% and Woxén equivalent chip thickness proves to work well for all presented tool life models. This work also discusses the models ability to reproduce cutting data for finishing operations and possible limitations when extrapolating the models for smaller chip thicknesses.
