Abstract
Die and mold machining usually necessitate employment of milling tools with long shanks. However, economic and technical design requirements often enforce low frequency structural vibration characteristics in work-pieces, especially in an area distanced from the tool holder. These structurally unstable designs pose a challenge for milling operations. The associated vibrations invariably reduce the quality of the work-piece produced and drastically increase average processing time and costs. This paper deals with cutting techniques used in face milling operations under semi-stable and unstable conditions. The strategy to use milling tools with integrated stepped cutting passes shows, that the use of smaller cutting ratios b/h, the chatter characteristics of the process could be significantly improved, thereby increasing the performance of the milling process.
