A multi-axis roll-forming system for forming a stepped diameter in a cylinder includes a support that spins about a rotation axis while supporting a workpiece that includes the cylinder. A first actuator translates a first roller perpendicularly to the rotation axis. A second actuator moves a multi-axis roller radially outward, relative to the rotation axis, and upward along the rotation axis. The system may also include a first roller arm to which the multi-axis roller is coupled. The first roller arm is connected to a pivot joint having a pivot axis that is perpendicular to the rotation axis. The second actuator may include a linear-drive actuator that is coupled to the first roller arm and extends along the rotation axis to force the multi-axis roller to pivot about the pivot axis.
