Abstract

The increase demand of industrial projects seeking more and more harmonic shapes for the presentation of a product, made the use of objects containing complex geometrical forms more frequent. Nowadays they can be found in a computer mouse, telephone, packing bottles, toys, medical industry and also in several components of a an automobile. Dies and molds, which are important tools employed in the manufacturing of these components, usually are made of high strength steels (hardened) and manufactured using machining processes. The use of high speed milling (or also called high speed machining) is becoming frequent in the manufacturing of dies and molds and, in this kind of process, machine tools with high spindle revolution and 5 controlled axes are necessary. A lot still has to be done to make this operation cheaper and more productive. This work aims to address some points that still have to be developed related to this process, like the milling of complex profiles using 3 or 5 coordinated axis, the tool vibration, which frequently is long and with small diameter, the analytical prediction of chatter in this process and the problem of the small chip thickness related to the tool edge radius. At the end of this project, besides having many interesting results for the dies and molds industry, we also intend to have contributed to the formation of many students in different levels (undergraduate, master and doctorate).
