5.5 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.
Defintion
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.
