Abstract
Hard turning is a potential machining process to replace for grinding process due to many advantages such as high material removal rate, good surface integrity, and friendly environment. Sintered tungsten carbide is widely used for the die and molds of the metal forming process because of their high hardness and wear resistance compared with alloy steel. CBN is a super hard cutting tool material used for machining difficult-to-cut materials as tungsten carbide. In this research, the influence of the cutting parameters including cutting speed, feed rate and cutting depth on the flank wear and surface roughness was analyzed by using 2k experimental model with some center points. The results investigated that the feed rate is the most significant parameter effecting on the surface roughness in the machining process and the cutting speed strongly affects on the flank wear in the hard turning of sintered tungsten carbide using CBN inserts. The results of ANOVA analysis for the surface roughness and the flank wear indicated that the curve models were required to describe the effect of the cutting parameters on the surface roughness and the flank wear in this machining process.
