抄録

For the efficient metal cutting operation, the chip control is one of the most serious problems at the present. In the turning operation, thin and/or ductile chips cause trouble because they are hard-ly broken. But, when a curved section is given to such chips, they can be broken at small deflection. Curved rake face for this purpose is studied in this paper, and cylindrical groove and spherical pit properly located on rake faces are shown to increase the chip breaking ability of tool. Based on the results of series of test, a rake face having a double spherical pit is developed. This rake face is very effective to produce broken chip in the turning under wide range of cutting conditions including very small feed. When the cutting tool with this shape of rake face is compared with standard tools, no apparent difference in cutting forces and tool wear are observed.
