Modeling Temperature Evaluation in Oblique Turning Using Finite Element Method
A model of the thermal process generated in metal cutting is developed in a finite element numerical approach. A family of transfer functions of a linear system is used to analyze the steady state response of the cutting temperature. The finite element model predicts temperature distribution in the workpiece, chip and tool and its variation with cutting parameters. The analysis requires the cutting forces and the chip geometry as inputs. Cutting forces were used to predict heat fluxes into chip formation zones. So, good correlation with the finite element model was found based on average tool edge temperature measurements. The tool workpiece thermocouple is used to monitor the thermal process in continuous three dimensional turning experiments.
