Defining the touch probe cycle in the Programming and
Editing mode of operation
U
The soft-key row shows all available touch probe
functions divided into groups.
U
Select the desired probe cycle group, for example
datum setting. Cycles for automatic tool
measurement are available only if your machine has
been prepared for them.
U
Select a cycle, e.g. datum setting at pocket center.
The TNC initiates the programming dialog and asks
for all required input values. At the same time a
graphic of the input parameters is displayed in the
right screen window. The parameter that is asked for
in the dialog prompt is highlighted.
U
Enter all parameters requested by the TNC and
conclude each entry with the ENT key.
U
The TNC ends the dialog when all required data has
been entered
