Output

The unprecedented scope of the physical sub-processes included in CALCut enables the three-dimensional stationary cutting front geometry and the resulting cut kerf geometry to be calculated.

CALCut identifies the spatial distributions of the absorbed laser beam power density, of the temperature, of thickness and flow velocity of the melt film along with the evaporation rates and pressure gradients.

Automatic iteration determines the highest possible cutting speed.

The analysis of the cutting front geometry and the above mentioned distribution functions also allows conclusions to be drawn about the achievable cut quality.
