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 81.
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.
To calibrate another tool, repeat steps 2 and 3.
Considerations for the offsets
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.
Data
Meaning

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.
