Tool calibration
2.7.5 Manual tool calibration without stopping the spindle
This feature may be used to manually calibrate the tool on a conversational lathe. It may be used
to calibrate tools without having to go back with the tool after performing a turning or facing operation.
Tool calibration is done without having to stop the spindle at each pass. It saves the tool position
in each touch and it applies the calibration by measuring the part only once at the end of the process.
Operation
Follow these steps to manually calibrate the tool:
1. After placing the part in the spindle and start the spindle, perform a facing operation.
2. Place the focus on "MEMO Z" and press the two-color key to save the current position
(coordinate).
Besides pressing the two-color key, pressing the [INS] or [-] key also memorizes the current
position. Once the position has been saved, enable "APPLY Z".
3. Withdraw the tool along the Z axis.
4. Perform a turning operation, place the focus on "MEMO X" and press the two-color key to save
the current position (coordinate).
Besides pressing the two-color key, pressing the [INS] or [-] key also memorizes the current
position.
5. Withdraw the tool along the X axis.
6. Stop the spindle and measure the resulting diameter of the turning operation just done.
The memorized positions are kept until a new calibration is applied or until quitting the tool cycle.
When quitting the cycle, a message warns that the saved data may get lost.
7. After filling the data out, the calibration may be applied on each axis (APPLY X or APPLY Z) or
on all the axes whose position has been memorized (APPLY ALL) so it assumes the new
calculated offsets. This is also possible with the Y axis.
It is also possible to delete the memorized position by pressing the [CLEAR] key when the focus
is on APPLY X, APPLY Y, APPLY Z or APPLY ALL. This way, a position may be corrected without
having to exit the screen.
The following hotkeys may be used to access the data quickly:
• The X, Y, Z keys give access to the fields for the part measurements before machining and to
the tool offsets for each axis.
• The M key gives access to the "MEMO" option used to memorize the positions.
• The A key gives access to the "APPLY" option used to apply the calibration.
Set bit 13 of general machine parameter CODISET (P147) = 0 to enable this calibration.
