When processing ductile metals with high cutting speed, there is a need to take additional measures for a comfortable and safe formation and removal of chips. In the conditions of large-scale manufacture, it is recommended to produce flow chips in the form of short fragments, while in the conditions of small-lot and single-piece manufacture, it is reasonable to wrap the chips spirally with a rather small turn radius. Such way of chips formation reduces the time of its removal from the working area as well as facilitates its transportation and processing. In order to solve the problem of chip wrapping and breakage, almost all modern manufacturers of tools with replaceable many-sided plates (RMSP) followed the way of complication of tool faces and determination of the areas of effective chip breaking. On the one hand, the suggested solution turns out to be effective; however, as showed the analysis of recommended cutting modes for complex forms of RMSP made by leading manufacturers, they all correspond to the definite cross section of the cut-layer S/t=0.1.
