13.6 CHANGING ACTIVE OFFSET VALUE WITH MANUAL MOVE
If you want to perform roughing or semi-finishing with a single tool,
you may fine-adjust the tool length compensation or cutter
compensation. Moreover, you may want to fine-adjust the setting of
the workpiece origin offset that was already set up. This function can
change the offset (such as tool length compensation, cutter
compensation, or workpiece origin offset) for the currently valid offset
number or workpiece coordinate system among those specified, by
adding an amount of axis movement made by manual feed
automatically.
Explanation
- Active offset change mode
This mode is specified by an active offset change mode signal
(specified from the machine operator’s panel). In this mode, an amount
of axis movement made by manual feed is automatically added to the
offset (such as tool length compensation, cutter compensation, and
workpiece origin offset) for the currently valid offset number or
workpiece coordinate system among those specified. The types of
manual feed valid with this function include manual handle feed,
incremental feed, and jog feed.
- Specifying an offset to be changed
An active offset selection signal (specified from the machine operator’s
panel) is used to select a tool length compensation, cutter compensation,
or workpiece origin offset. In active offset change mode, the selected
offset is indicated by blinking its status indication as listed below.

- Changing the tool length compensation
This function can change the tool length compensation identified by the
offset number corresponding to an H code specified during automatic
operation. If there is no valid tool length compensation (for example,
just after a reset is executed or when no H code has been issued since
cycle start), no tool length compensation change takes place even when
axis movement is made manually.
The tool length compensation can be changed by movement along the
basic three axes (X, Y, Z) and any axis parallel to one of them (that is,
an axis with parameter No. 1022 set to a nonzero value). It cannot be
changed using rotation axis movement. When the tool length
compensation is being changed, manual feed cannot cause movement
along more than one axis at a time.
