6.5 Tool offset number (D)
The tool offset contains the tool dimensions. Each tool may have several offsets associated
with it in such a way that when using combined tools having parts with different dimensions,
a different offset number will be used for each of those parts.
When activating a tool offset, the CNC assumes the tool dimensions defined for that offset,
therefore when working with tool radius or length compensation, the CNC will apply those
dimensions for compensating the path.
Definition
To activate an offset, it must be previously defined. To do that, the CNC offers a portion of
the tool table where the user may define several offsets. The table data may be defined:
• Manually from the CNC's front panel (as described in the Operating Manual).
• Via program, using the associated variables (as described in the relevant chapter of this
manual).
The offsets are only associated with the tool for which they have been defined. This means
that when activating a tool offset, the offset of the corresponding active tool will be activated.
Activation
Once the tool offsets have been defined in the table, they may be selected by program using
the "D<n>" code where <n> is the number of the offset to be applied. The offset number may
also be defined using a parameter or an arithmetic expression.
If no tool offset is programmed, the CNC assumes tool offset D1.
Only one tool offset may be active at a time; therefore, activating a tool offset will cancel the
previous one. Programming "D0" will cancel the active offset.
