Comparison of the Wear of Toroidal and Spherical Cutters in Milling and the Impact of Corrosion

In this study, the tool axis inclination angle with respect to the surface normal is used to compare the wear of spherical and toroidal milling cutters. Five different surface types were machined in this investigation using three toroidal and three spherical milling cutters at inclination angles of 15°, 35°, and 55°. Each cutter processed 45 surfaces, nine of each type. The MM1-200 microscope was used to monitor tool wear under a microscope after the surfaces had been machined. A comparison diagram and microscopic pictures of tool wear in relation to the wear surface are presented in the paper. Additionally, it contrasts the tool edge’s state at the conclusion of machining with its state following five years of storage, during which time the tool was subjected to environmental influences.
