Laser Precision Cutting of High-melting Metal Foils

Abstract

The conventional processing of high-melting metal foils by means of wire eroding is time-consuming and thus cost-intensive. Other procedures such as e.g. milling cannot be realised at all or only with high efforts. Laser beam cutting is a more economical alternative, which is, however, technically very demanding due to the high melting point of the examined foil materials. Different cutting methods and types of laser were used in the examinations in order to achieve a distortion-low and high-quality cutting of the materials in the sintered and unsintered state at high process velocities.
