Ball burnishing is a surface compression method for improve roughness and hardness. But which are the industrials uses of this method?
If you have a laser cutting machine that can cut a steel sheet up to 10 mm thick, is it possible to cut a 20 mm steel sheet in two consecutive passes? If the answer is yes or no, why?
