The Oxley modeling approach, its applications and future directions

The Oxley machining theory which allows for the high strain-rate/high tempe rature Row stress and thermal properties of the work material is described. It is shown how the theory that was originally developed for the orthogona l process and later extended to oblique machining, can be used to predict c utting forces, temperatures and subsequently built-up edge formation condit ions, tool life and cutting edge deformation conditions. It is also shown h ow the theory can be applied to obtain predictions in machining with restri cted contact tools and in intermittent cutting processes, and to obtain wor k material properties using machining test results. Finally, some considera tion is given to the future directions of machining research at UNSW. The O xley Model can be used for predicting the performance parameters for differ ent machining processes by taking into account the fundamentals of the chip formation process.
