In this study, the effects of the treatment (applied to cutting parameters and cutting tool) on the cutting forces, surface roughness and tool life were investigated. Part of the cutting tools was subjected to a cryogenically treatment at -145 degrees C for 24 h. The effects of the cryogenically treated and untreated cemented carbides (uncoated) on the cutting forces, surface roughness and wear behaviors were investigated. Machinability tests were carried out at four different cutting speeds (30, 45, 60, 75) m/min, three different feed rates (0.20, 0.25 and 0.30) mm/r and the 1 mm cutting depth. Wear tests were made for four different chip volumes (20, 40, 60 and 80) cm(3), four different cutting speeds (30, 45, 60, 75) m/min, the 0.25 m/r feed rate and the 1 mm cutting depth. At the end of the tests, the cryogenically treated inserts gave better results compared to the untreated tools with respect to the wear behavior, cutting forces and surface roughness.
