4-4 Starting Tool-length Offset
When Tool-length Offset Starts
Tool-length offset is activated in the following cases. In each of these cases, the offsets are applied according to the registered
adjustment values. (You can use the [Magazine] dialog box to view and check the adjustment values.) Note, however, that
the adjustment values are all zero by default, and unless you change them, no offsets are applied.
RML-1 Mode
In the RML-1 mode, offsets are always applied according to the registered adjustment values. The offset is applied when a
tool-grasping operation is performed, whether according to a command from the computer or by a manual tool-change.
NC-code Mode
In the NC-code mode, no offsets are applied unless an offset-start command is given in the NC program. Note, however, that
offsets are applied only during manual feed after a manual tool-change.
Tool-length Offset in a Manual Tool-change
The following events occur as a result of offset application due to a manual tool-change.
Manual Feed
The Z-axis coordinate view is updated to reflect the tool-length offset.
Cutting Operations in the RML-1 Mode
If the program you're using doesn't support the ATC (that is, if it's a program incapable of automatic tool-change), you can
still perform cutting by grasping the tool using manual tool-change. Tool-length offset is applied at this time as well. Note,
however, that this does not occur in the NC-code mode.
Correspondences Between Stocker Numbers and Offset Numbers
RML-1 Mode
Being aware of any differences between stocker numbers and offset numbers is not necessary. In the RML-1 mode, the stocker
numbers and the offset numbers are always identical.
NC-code Mode
In the NC-code mode, it's necessary to be aware of any differences between stocker numbers and offset numbers. For instance,
offset No. 2 may be assigned to stocker No. 1. The combinations are all specified by the NC program.
Manual Tool-change
In manual tool-changes, the stocker number and the offset number are always the same. Offset No. 2, for example, can never
been assigned to stocker No. 1, not even in the NC-code mode.
