Presetting with an end mill
Select Manual operation mode
Move the tool slowly until it touches (scratches)
the workpiece surface
Setting a preset in an axis:
Select the axis
The control opens the PRESETTING Z= dialog
window
Alternative: Press the SET PRESET soft key
Select the axis via soft key
Zero tool in spindle axis: Set the display to a
known workpiece position (here, 0) or enter the
thickness d of the shim. In the tool axis: Consider
the tool radius
Repeat the process for the remaining axes.
If the tool in the tool axis has already been set, set the display of the
tool axis to the length L of the tool or enter the sum Z=L+d.
Operating notes:
The control automatically saves the preset set with
the axis keys in row 0 of the preset table.
If the machine tool builder has locked an axis, then
you cannot set a preset in that axis. The soft key for
that axis is then not visible.
The behavior of the control during presetting depends
on the setting in the optional machine parameter
chkTiltingAxes (no. 204601).
