Temperature
field determination for orthogonal metal cutting |
| Abstract
: |
|
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.
