(REF: 1807)
When a lathe has a third axis perpendicular to the work plane ("trihedron" geometrical
configuration), the CNC will also show its data and calibration will be possible on that axis.
The data of the third axis may be hidden or shown using the horizontal softkey menu.
For a milling tool.
Tool calibration steps
To calibrate the length, follow these steps.
1 Define the dimensions of the reference part being used in the calibration.
2 Select the tool and the offset to be calibrated. After the selection, the CNC shows the
dimensions defined in the tool table for that offset.
To calibrate a tool, it must be the active tool. When selecting a tool and pressing [ENTER],
the CNC only shows the data for that tool. Press [CYCLE START] for the CNC to make
the tool change so it becomes the active tool. See "Selecting a tool" on page 137.
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.
D Tool offset to be calibrated.
Off Y
Off X
Tool offsets on each axis.
Lw Offset wear on each axis.
Data Meaning
Zp Coordinate of the reference part being used in the calibration. This coordinate is
referred to the longitudinal axis of the tool.
T Tool to be calibrated.
D Tool offset to be calibrated.
L Tool length.
Lw Length wear.
R Tool radius.
Rw Radius wear.
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.
