This paper considers two of the major problems associated with the design and manufacture of ball-end cutters whose cutting edge lies at a constant angle to the axis. The first problem involves the inability to solve the mathematical description of the cutting edge at the top of the ball-end cutter, while the second problem relates to the tendency of the grinding wheel feeding speed description to approach infinity in the same region. Mathematical models are developed to overcome these problems. These models provide a valuable reference for the future design and manufacture of cutters of this type.
