Abstract
TiN coated and uncoated tools were used to conduct the dry cutting temperatures for AISI 304 stainless steel. Effects of cutting variables on cutting temperatures were investigated using single factor experiment method. The optimal cutting parameters of cutting temperatures were obtained through orthogonal experiment method. The forming process and temperature distribution of chips were analyzed using finite element method (FEM). The results show that cutting temperature generally increases with the increase of cutting speed and feed rate. When depth of cut increases at the range of 0.8-1.5 mm, the cutting temperature increases firstly and decreases subsequently. And the cutting temperature of TiN coated tool is lower than that of uncoated tool. The optimal parameters of cutting temperature are obtained by orthogonal experiment, which is A1B1C3. The highest temperature appears on the second deformation zone by the simulation.
