Experimental results show that it is possible to increase cutting tool life substantially by a proper variation of the cutting feed rate throughout the cutting process. Experiments clearly demonstrate this phenomenon which is most prevalent for the machining of hard materials. Experimental results show a decrease of approximately 60% in tool wear indices for the machining of steels with a high chromium content (60 Rc). Comparisons between constant and variable feed processes are based on constant volume of material removed in a given time span, therefore maintaining a constant process efficiency for both cases.
