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, 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. 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.
