| Abstract: | In the experiment,two different kinds of coated cemented carbide tools were used to cut austenitic stainless steel 1Cr18Ni9Ti;tool wear modalities and fracture surfaces were observed by means of SEM and EPMA;chemical composition of the abrasion area and fracture surfaces were analyzed.Using the same cutting parameters,as the results indicated,the cutting force of GC2025 is smaller than that of YBC251;the tool life of GC2025 exceeds that of the latter,of which abrasion and breakage are obvious and oxidative ... |
