Operating notes:
The rotation of the workpiece creates centrifugal
forces that lead to vibration (resonance), depending
on the unbalance. This vibration has a negative effect
on the machining process and reduces the tool life.
The removal of material during machining will change
the mass distribution within the workpiece. This
generates the unbalance, which is why an unbalance
test is recommended even between the machining
steps.
Unbalance Monitor function
The Unbalance Monitor function monitors the unbalance of a
workpiece in turning mode. If a maximum unbalance limit specified
by the machine manufacturer is exceeded, the control issues an
error message and initiates an emergency stop. In addition, you
can further decrease the permissible unbalance limit by setting
the optional machine parameter
limitUnbalanceUsr
(no. 120101). If
this limit is exceeded, the control issues an error message. Table
rotation is not interrupted in this case. The control automatically
activates the Unbalance Monitor function when you switch to
turning mode. The unbalance monitor is effective until you switch
back to milling mode.
