See also: Four Axis Turning
The Four Axis Turning option allows you to use more than one turret at the same time in the turning environment. This means you can use two fixed cutting tools in the same cycle, using the Four Axis commands from the Cycles menu.
In Balanced cycles, the Upper and Lower turrets work opposite each other about the Z axis. These cycles have an additional parameter called Z Lead. Using a value here instructs the currently active turret to cut in front of the other turret by the Z Lead distance.
The Four Axis cycles operate in the same way as the Two Axis cycles Straight Turn and Rough Turn, except that two turrets are used for the same cycle at the same time. The leading turret is the currently selected (active) turret.
