Abstract:
1. A metal-cutting machining method for a semi-finished product having a predetermined shape and at least one machining surface, the method comprising: sticking a protective foil having a predetermined elongation at break onto the at least one machining surface with a predetermined adhesive force, wherein the protective foil is coated with an acrylate dispersion adhesive; setting a cutting tool in a predetermined position above the machining surface; exerting a predetermined mechanical force in a predetermined direction over a predetermined length of time on the tool for carrying out a machine-cutting process on the semi-finished product; and lifting the tool away from the at least one machining surface after the predetermined length of time, wherein a primer layer is provided on the machining surface, an adhesive force exists between the protective foil and the machining surface of the semi-finished product of 10 N/25 mm and the protective foil has an elongation at break of between 80 and 120%.
