Abstract: Aiming at the problems that there is no equation for crosscutting feed to calculate the durability of cutter, by researching the wear process of crossingcutting feed, the wear influenced by cutting data(cutting speed υc、feed data f、cutting depth ap) was analyzed. According to F.W.taylor , equation to calculate the working life of cutting data and cutter was established.In CY6140 lathe,turning tools with carbide YT5, the parameters of the carbon steel crosscutting feed(υcmax=175 m/min，f=0.2 mm/r，ap=5 mm)were taken for grooving experiment 30 times. The results indicate that equation for crosscutting feed to calculate the working life of cutter according is feasible.
