3.2 Piston Lathe
* Cutting Sequence
(1) The piston outside is cut by rotating the spindle to move the tool back and forth along the Y axis. By feeding
the tool along the Z axis, the piston outside is gradually cut deeper.
(2) Both Y axis and C axis use the Suspension mode or the Continuation mode of the Learning control. When
the command of Y axis gradually changes, Y axis should use the Continuation mode of the Preview
repetitive control. If changing rate of the command is small, the Continuation mode of the Learning control
might be sufficient for Y axis.
