8.1 Working with Cycles
Frequently recurring machining cycles that
comprise several working steps are stored in the
TNC memory as standard cycles. Coordinate
transformations and other special cycles are also
provided as standard cycles (see table on next
page).
Fixed cycles with numbers 200 and above use Q
parameters as transfer parameters. Parameters
with specific functions that are required in several
cycles always have the same number: For example,
Q200 is always assigned the set-up clearance, Q202
the plunging depth, etc.
Defining a cycle using soft keys
U U U U The soft-key row shows the
available groups of cycles.
U U U U Press the soft key for the desired
group of cycles, for example
DRILLING for the drilling cycles.
U U U U Select a cycle, e.g. DRILLING. 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 U U U Enter all parameters asked by the
TNC and conclude each entry with
the ENT key.
U U U U The TNC terminates the dialog
when all required data has been
entered.
