Abstract Scope |
We consider the contact between a sliding wedge/tool and a metal surface prototypical of material removal and deformation processing operations such as forming, cutting and wear. We show how heat generated at the contact is partitioned into each of the bodies involved - tool, workpiece, removed chip and surrounding fluid (if any). By performing thermal analysis and heat partition via temperature matching on global and local scales, we show how temperature fields in all four bodies can be easily calculated. The analysis framework involves a heat source moving over a body (Jaeger), and energy partition at the contact into tool, workpiece, fluid and chip/wear particle (Blok). We present temperature solutions for two cases – incremental forming and grinding - while providing a simple method for solving the thermal problem in other deformation processing applications. |
