3.1 Machine mode of operation
The Machine mode of operation includes all functions for machine
setup, workpiece machining, and Teach-in program definition.
 Machine setup: For preparations like setting axis values (defining
workpiece zero point), measuring tools or setting the protection
zone.
 Manual mode: Machine a workpiece manually or semi-
automatically.
 Teach-in mode: "Teach-in" a new cycle program, change an existing
program, or graphically simulate cycles.
 Program run: Graphically simulate existing cycle programs or
smart.Turn programs and use them for the production of parts.
A Teach-in cycle is a machining step that has already been
programmed for you. This can be any machining operation from a
single cut through to a complex machining task like thread cutting. In
any case, a cycle is always a complete machining step that is
immediately executable once you have defined a few parameters that
describe the workpiece to be machined.
In Manual mode, the cycles that you program are not stored. In
Teach-in mode, each machining step is executed with a cycle and then
stored and integrated into a complete Teach-in program. You can
subsequently use this program in parts production by repeating it as
often as desired in the Program Run mode.
In ICP programming, any contour can be defined using linear/circular
elements and transition elements (chamfers, rounding arcs,
undercuts). You include the contour description in ICP cycles (see "ICP
contours" on page 360).
You write smart.Turn and DIN programs in the smart.Turn mode of
operation. The DIN programming feature provides your with
commands for simple traversing movements, DIN cycles for complex
machining tasks, switching functions, mathematical operations and
programming with variables.
You can either create "independent" programs that already contain all
necessary switching and traversing commands and are executed in
the Program Run mode, or program DIN subprograms that are
integrated in Teach-in cycles. The commands that you use in a DIN
subprogram depend on the job at hand. DIN subprograms support the
complete range of commands that is available for DIN programs.
You can also convert Teach-in programs to smart.Turn programs. This
enables you to make use of straightforward Teach-in programming,
and then convert the part program to DIN format for subsequent
optimization or completion.
