6.3 Crowning device programming and adjusting
The crowning device position and the crowning device adjustment are necessary to work
properly with the crowning device.
Crowning device position and adjustment for calculated purposes
When you use the calculated crowning device then the required crowning is based on the
programmed values of three machine parameters. The following machine parameters must
therefore be programmed (See also Y-axis and general parameters of chapter 3):
•
inertia upper beam;
•
inertia under beam;
•
machine length.
The required crowning value is calculated (computed value in data preparation and data editing).
To be sure that the crowning device reaches the computed position, the crowning device should
be adjusted as follows:
•
Go to to the auxiliary menu and program axis ‘CROWNa’.
•
Press ‘change parameters’.
•
Program for Min. value and DA-min 0.
•
Program for Max. value and DA-max 255 (standard resolution) or 1023 (high resolution).
•
Move the crowning device to its mechanical minimal position by means of the handwheel.
•
Measure the deflection in hundreds of mm. Remember this value and program it at the end of
the adjustment procedure for the parameter Min. value. The programmed Min. value is the
measured value times hundred. Measured value 1.05, programmed value 105 (In most cases
this value will be near to zero).
•
Read out the deflection value on the screen (Manual mode, manual positioning). This value
corresponds with the number of DA-points. Remember that value and program it at the end
of the adjustment procedure at the parameter DA-min.
•
Now move the crowning device to its mechanical maximal position.
•
Measure the deflection in hundreds of mm. Remember this value and program it at the end of
the adjustment procedure for the parameter Max. value. The programmed Max. value is the
measured value times hundred.
•
Read out the deflection value on the screen (Manual mode, manual positioning). This value
corresponds with the number of DA-points. Remember the value and program it at the end of
the adjustment procedure at the parameter DA-max.
•
Program now the found values to the corresponding machine parameters.
Example
The crowning device position must always be programmed in 0.01 mm units and the initial value
and the decimal point position must be 0.
•
The minimal deflection = 0 mm at 25 DA-points.
•
The maximal deflection = 1.20 mm at 185 DA-points.
For this example the crowning device parameters must be programmed as follows:
DA-min. = 25
Min. value = 0
Max. value = 120
