Function
The Machine operating area contains all the functions and control
variables that trigger actions on the machine tool or detect its status.
There are three different modes in this area:
· Jog: Jog is the mode required for manual operation and setting up
of the machine. The setup functions provided are "Reference point
approach", "Repositioning", "Handwheel" or "Traverse in preset
increments" and "Redefine control zero" (preset).
· MDI: Semi-automatic operation
Part programs can be set up and processed block by block in this
mode. The tested blocks can then be stored in the part program.
In Teach In mode, positions can be traversed and stored to
generate motion sequences which are then stored in the MDI
program.
· Automatic: Fully automatic operation
Part programs are executed fully automatically in Automatic mode,
i.e. they are selected, started, corrected, selectively manipulated
(e.g. single block) and processed.
You can switch to the "Machine" area at any time from any of the
other operating areas simply by pressing the "Machine area" key.
When you switch on the control, it is usually in the operating area
"Machine" in operating mode "Jog".
Please consult the documentation provided by the machine
manufacturer!
