Abstract

High-speed milling is one of the new modern technologies in machining. It is radically different from the known method of the conventional milling in fundamentally different process specified by the modified mechanism of the cutting process. This article presents a theoretical model to determine the coefficient of unevenness aimed at giving information whether already selected cutting conditions in cylindrical milling is admissible. This makes it possible to use the power of the machine most conveniently, to improve the quality of the machining and to achieve a relaxed operation. The model is based on derived mathematical equations
