2.1 Working with Fixed Cycles
Defining a cycle using soft keys
U The soft-key row shows the available groups of cycles
U Press the soft key for the desired group of cycles, for
example DRILLING for the drilling cycles
U Select the desired cycle, for example THREAD
MILLING. The TNC initiates the programming dialog
and asks 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
