MODELING OF TOOL CHIP INTERFACE TEMPERATURE DISTRIBUTION IN METAL-CUTTING

Modelling of the tool/chip interface temperature distribution during o rthogonal metal cutting is presented. To make the model more realistic , the shear plane is assumed to be inclined to the chip velocity as ge nerally occurs. It is shown this geometrical condition can be relaxed, which results in considerable mathematical simplification. The temper ature distributions obtained along the chip back (chip/air interface) from the analysis are also compared with previous results and with dir ect experimental data. Better agreement is found between the proposed model and the experimental evidence.
