Abstract

Traditional machining processes, such as face milling, still play a very important role in the production of machine parts and are the subject of ongoing research. One important area of research is the investigation of high-feed milling processes. However, due to the increased feed per tooth value fz, it is advisable to reduce the depth of cut (ap) in order to maintain the cutting forces at an appropriate level. In this way, the ratio of these two technological parameters, the so-called cutting ratio, changes and we can move into the range of inverse machining, where ap / fz < 1. In this paper, the consequences of this change is investigated on the surface roughness and the components of the cutting force, and it is discussed how the optimal cutting ratio can be found.
