STUDYING THE EFFECT OF CUTTING SPEED AND FEED RATE ON TOOL LIFE IN THE TURNING PROCESSES

Abstract

In this paper, a thorough investigation has been carried out to study the effect of cutting speed and feed rate on tool life at constant depth of cut equal to (1mm) with no cooling fluid. Different cutting speed and feed rate with constant depth of cut are used to optimize these variables for maximum life can be obtained experimentally. The experiments were conducted on the fermented low alloy steel and using high hardness cutting tool of Tungsten Carbide. It was found that the longest life of cutting tool is at cutting speed (66.88 m / min) and feed rate (0.72 mm / rev), where the life of cutting tool is(388.3 min). The shortest life of cutting tool occurring at cutting speed of (263.76m/min) and feed rate (0.8 mm / rev), where the value of the life is about (0.274 min). Thus, we clear note that the cutting speed and feed rate have a direct impact on the longevity of the kit.
