Abstrakt EN: This article deals with special kind of machining of multi-layer laminar composites called sandwich composites. This material consists of two outer layers that overlap core material at the centre made from a light material. This material is used in the automotive industry in interior parts such as dashboards, decorative parts and panels. The product is folded from thin plastic and aluminum. As customers require high-end quality for higher class-vehicles, machining must be ensured at as high a level as possible to suit customer demands. Appropriate processing methods have been investigated experimentally in order to choose the best tool that would guarantee a consistently high quality of cut depending on high durability. Therefore it is still necessary to permanently test new tools with different types of coating, including thin films and different geometry to achieve the required quality at less clamping milling tools, which need to be changed after some pieces and edge sharpen.
