Predicting the outcomes of laser thermal forming
Applying a laser or any other high-density heat source to the surface of a metal sheet for a short time will distort the metal. If this distortion could be predicted, the laser could be directed so that the sheet metal would form the desired shape. This idea opens up many possibilities,... Read more...
