Study on Interrupted Hard Turning : Effect on Extending Tool Life by Applying an Oblique Cutting Method(Advanced machining technology (continued))

概要

For materials having a hardness of 60 HRC or more, continuous cutting is possible with CBN tools and ceramic tools in conventional single-point cutting processes. However, in interrupted cutting of the spline outer diameter of transmission parts, there is the problem that tool life is shortened by the continuous impulse force acting on the tool cutting edge. To avoid that problem, we applied an oblique cutting method in interrupted cutting, and investigated the effect on tool life. The results showed that tool life was substantially extended compared with conventional single-point cutting, and that surface roughness was also reduced in comparison with conventional grinding processes.
