A study on the stress analysis for rake face of a tool with crack in cutting process

적삭중인 공구의 경사면상에 crack을 갖는 경우의 응력해석에 관한 연구

The determination of stress distributions on the rake face of tool are important to understand the mechanism of metal cutting. For this reason, many researchers have been payed much effort to analyize machining stress distribution on the rake face. The author's photoelastic experiment has shown that the stress distributions on a rake face can be obtained photoelastically by using a specially designed tool made of epoxy resin plate, and also, Stress Intensity Factors $k_{I}$, $k_{II}$ and Crack Extension Angle can be deter mined by using Linear Elastic Fracture Mechanics.ics..
