Abstract [en]

In this study a systematic approach for understanding the cutting process in CGI machining is be presented. Tool wear, tool temperature, measured with an IR camera,and cutting forces were investigated. CGI material properties were studied and contact zones on the inserts analysed. Quick stop tests were performed and a FEM temperature model, built on both experimental- and modelled data developed. The experimental data were used, both to calibrate and validate the temperature model. The results showed that increasing nodularity led to higher cutting forces and temperature. Increasing nodularity had impact on wear at moderate and high cutting speed but not at lower cutting speed. Classification of the wear mechanisms gave knowledge that could be used for tool design.The results demonstrate the need of complementing the IR camera temperature measurement with modelling to acquire an estimation of the temperatures in the cutting zone.
