3 Calibrate the tool. Approach the tool manually until touching the part and then validate
the calibration using the softkey menu.
After validating the calibration, it updates the values and initializes the wear value to zero.
Them, the new values are saved in the tool table.
4 Press [START] for the CNC to assume the new values of the offset.
To calibrate another tool, repeat steps 2 and 3.
Considerations for the offsets and their wear.
It must be borne in mind that the offset of a tool on an axis is the distance between the base
of the tool and its tip (nose). This means that when calculating the offset of a milling tool on
an axis that includes the radius dimension, that radius is included in the offset. The same
is true for the tool length.
When calibrating the offsets of a milling tool, the length value is deleted but not the radius
value.
Sign criteria for the offsets and their wear.
The sign criterion for the offsets and their wear is established by machine parameter
TOOLOFSG.
Entering wear values incrementally or absolutely.
In the tool table, it is possible to define whether the wear value being entered must be
incremental or absolute.
Using incremental wear, the value entered by the user will be added (or subtracted if it is
negative) to the absolute value of the wear. After pressing [ENTER] to accept the new value,
the wear field will show the resulting absolute value.
TOOLOFSG Meaning.
Negative. Tool calibration returns a negative offset. The offset wear must be entered with
a positive value.
Positive. Tool calibration returns a positive offset. The offset wear must be entered with
a negative value.
