Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the roller-metal interfaces.

For a spur gear or straight spline, it is a straight cut, so it requires only a four-axis machine (or a three-axis machine with a rotary table) and no special cycles. For a helical, a five-axis machine or a four-axis with a head with the ability to tilt the cutter is needed, and still no special cycles are needed. Figure 4: Disc cutters
