The paper aims to study the effect of four values of the rotational speed of the cutting tool (600, 700, 800, 900) r.p.m as a function of the cutting speed of the peripheral milling versus of five values of the feed rate (0.4, 0.6, 0.8, 1.0 and 1.2) mm on the tool life in peripheral milling, using medium carbon steel (DIN CK45), The tool life was calculated theoretically and experimentally using Taylor's Equation for (60) test specimens.

Search Results showed that moderate feed rates with medium-cutting speed of machine peripheral milling give a longer life to the tool cutting, and that the increase in cutting speed with the feed rate more than the right one leads to the collapse of the cutting edge of the milling cutter in the peripheral milling process, and the pieces that fall between (100 speed m / se) and (125 m / sec) with a little feed rate (0.6 mm) are the values that check Tyler's equation, and the study proved that the tool life rate would be appropriate for the peripheral milling operations at medium speeds and moderate feed rates, as the cutting speed with high feed rate greater than (1 mm) leads to reduced cutting tool life during operations, and that the current study has given practical results achieved Tyler 's logarithmic equation.
