Quality Analysis of Roughing Reamers That Use WNMG080408–P30 Mechanical Fixed Cutting Inserts

Abstract

Due to the many advantages, the using of mechanical fixed cutting inserts extents to development of different cutting tools, like the reamers. Roughing reamers with switchable inserts that use WNMG mechanical fixed inserts are used for both enlarging and reaming. Knowing the value of the electrical current at cutting is important because it provides much information regarding the quality appreciation of the tool, which is determined by the tool life of the used cutting inserts. In this paper there are experimentally determined values of the electrical current at cutting at processing 1C45 steel with roughing reamers in the range of diameters of 20÷153 mm that use at cutting edge mechanical fixed WNGB080408-P30 cutting inserts.
