Defining A Cycle Using Soft Keys; Defining A Cycle Using The Goto Function - HEIDENHAIN TNC 620 User Manual

Using Fixed Cycles | Working with fixed cycles

Defining a cycle using soft keys

The soft-key row shows the available groups of
cycles
Press the soft key for the desired group of
cycles, for example DRILLING for the drilling
cycles
Select the cycle, e.g. THREAD MILLING. 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.
Enter all parameters requested by the TNC and
conclude each entry with the ENT key
The TNC ends the dialog when all required data
has been entered

Defining a cycle using the GOTO function

The soft-key row shows the available groups of
cycles
The TNC shows an overview of cycles in a pop-
up window
Choose the desired cycle with the arrow keys, or
Enter the cycle number and confirm it with the
ENT key. The TNC then initiates the cycle dialog
as described above
