MANUAL (JOG) MODE. TOOL CALIBRATION
(REF: 1505)
Semi-automatic calibration. Calibration with a probe
Bear in mind that in this calibration mode, the [CYCLE START] key has two functions. If a
new tool has been selected, it executes the tool change. If the selected tool is the active one,
pressing [CYCLE START] initiates the calibration.
Calibration in a mill model
On milling tools, it calibrates the radius and length of the tool. After calibrating one of the two
dimensions, its wear value is reset to zero.
For the lathe tools, it calibrates the tool offsets on each axis. The offset wears are set to zero.
Calibration in a lathe model
For the lathe tools, it calibrates the tool offsets on each axis. When validating the calibration
in one of the offsets, the wear of that offset is reset to zero.
Validating the calibration
Use the horizontal softkey menu to select the axis and the moving direction for the calibration.
Once selected and after placing the tool in the spindle, press [CYCLE START] to start the
calibration. The tool will move in the indicated direction until touching the probe and it will
then conclude the calibration updating the tool data with the measured values.
Once the tool has been calibrated, the CNC shows a message proposing to press [START]
so the CNC assumes the new values of the offset. When pressing [START] while this
message is displayed, the CNC assumes the new values of the offset; if the message is not
displayed, pressing [START] executes the probing movement again.
Once a movement has been selected, the window will show a help drawing indicating the
type of calibration to be done, length or radius.
Definition of data
To define the data, place the focus on the relevant data, key in the desired value and press
[ENTER].
Tool calibration steps
To calibrate the tool, follow these steps:
1 Define the probing distance and feedrate. If the feedrate is not defined, the probing
movement will be made at the feedrate set by the OEM.
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 "Tool calibration" on page 117.
3 Manually approach the tool to the probe until it is placed on the path that will be used
for probing. To calibrate the radius with a cylindrical probe, the path must coincide with
the probe's center point; if not, the radius will be calculated wrong.
Data Meaning
PRBMOVE Maximum probing distance. If the CNC does not receive the probe signal before
reaching moving this probing distance, it stops the axes.
F Probing feedrate.
T Tool to be calibrated.
D Tool offset to be calibrated.
LTool length.
Lw Length wear.
R Tool radius.
Rw Radius wear.
