TEMPERATURE FIELD DETERMINATION FOR ORTHOGONAL METAL CUTTING

Principle of virtual temperatures as applied to the problem of orthogonal cutting, included the dissipation terms associated with mechanical work, is used to computed the temperature field resulting from the interation between tool and workpiece. The problem is formulated, discretized and the resulting equations solved with the finite element method. As an application the temperature field is computed for the case of machining AISI 1020. The stress field is also shown in order to present the coupled problem. Material dependence with temperature, strain rate and strains is allowed in the model used. In general good agreement is obtained with results presented in the literature.
