Prediction of the cutting conditions giving plastic deformation of the tool in oblique machining

Abstract A method is described for predicting cutting conditions at which the cutting edge starts to deform plastically when machining with oblique nose radius tools. It is shown how tool stresses and temperatures determined from machining theory can be used together with experimental high temperature compressive strength data for the tool material to make these predictions. A comparison made between predicted and experimental results for two plain carbon steel work materials and a range of cutting conditions shows good agreement.
