Machining of complex rotary components is very complicated, which is why geometries are often simplified at the expense of efficiency. Only through the use of special machining centers and special tools is it possible to produce the complex geometries. However, high costs arise for the production of special tools. The objective of the „OpToRoMill“project was the development of a CAx process chain that enables production with conventional solid carbide cutters. © Carl Hanser Verlag GmbH & Co. KG.
