Unfortunately, users have no practical way to take advantage of this theoretical knowledge until recently. So not only is it possible to reduce tool wear and increase material removal at the same time, it is required if you are going to take full advantage of RCT. As stepovers are decreased, material removal rates must be increased to maintain constant chip loads and manage heat removal so that the cutting tool does not fail prematurely.

As stepovers decrease, tool wear decreases, too, as long as the chip load remains constant. RCT has to do with the behavior of cutting tools when stepovers are 50 percent or less. Question: Is it possible to improve material removal efficiency and increase cutting tool life at the same time?Īnswer: It is not only possible, it is required.įor more than 50 years, material scientists have known that the theoretical answer to this question is “yes.” This understanding is based on a phenomenon known as radial chip thinning (RTC). Here a small number of efficient, material-aware dynamic toolpaths are used to automatically blend transitions between steep and shallow areas to achieve the part geometry.
