Turning Operations

Turning operations generate a series of predetermined grinding/dressing
motions to turn or thread a part. The major topics covered in this chapter
include:

Important: We assume that your control is in the G18 plane and you
define that plane as the ZX plane. If your system has a different plane
active, operation of these features is different. Parameters defined here
assume that Z is the first axis in the plane and that X is the second axis in
the plane. If, for example, the XZ plane is the currently active plane,
descriptions in this document should be interpreted accordingly
(i.e., Z-axis description applies for X-axis and X-axis description applies
to Z-axis). See your system installer’s documentation for details on the
plane definitions on your system.

Single pass turning cycles consist of these cycles:

G20 - Single Pass O.D. and I.D. Roughing Cycle

G24 - Single Pass Rough Facing Cycle

We call these cycles single pass cycles because each time the cycle is
executed, it makes only one grinding pass over the workpiece or one
dressing pass over the grinding wheel. Typically, single pass cycles are
modal and repeat after any block that commands axis motion.

Your system installer can select in AMP to repeat the cycle after every
block following the single pass cycle block. If your control is configured
this way, the motions of the last executed single pass cycle repeat after
every program block until you cancel the cycle.
