Gear planning of helical gears with rack type cutters:


For cutting helical gear, the cutter is inclined in a vertical plane to reciprocate along a line inclined to the horizontal. The work axis is vertical, and the cutter is mounted on a vertical slide which can be swiveled in the vertical plane. The cutter reciprocates along the vertical slide, cutting during the downward stroke. During cutting the rolling motion is stopped. During the return stroke the cutter is relieved, and the workpiece is rotated in small increments and moves right to left by an amount equal to the distance a rack would travel for that amount of rotation of workpiece. This process is repeated until the whole gear is cut.
