Macro techniques
Grouping of a set of statements under a single identifier. The identifier represents the set of consolidated
statements in the program.
Main block
A block prefixed by ":" introductory block, containing all the parameters required to start execution of a -> part
program.
Main program
The term "main program" has its origins during the time when part programs were split strictly into main and →
subprograms. This strict division no longer exists with today's SINUMERIK NC language. In principle, any part
program in the channel can be selected and started. It then runs through in → program level 0 (main program
level). Further part programs or → cycles as subprograms can be called up in the main program.
MDA
Control operating mode: Manual Data Automatic. In the MDA mode, individual program blocks or block
sequences with no reference to a main program or subroutine can be input and executed immediately afterwards
through actuation of the NC start key.
Messages
All messages programmed in the part program and → alarms detected by the system are displayed on the
operator panel in plain text with date and time and the corresponding symbol for the cancel criterion. Alarms and
messages are displayed separately.
Metric measuring system
Standardized system of units: For length, e.g. mm (millimeters), m (meters).
Mirroring
Mirroring reverses the signs of the coordinate values of a contour, with respect to an axis. It is possible to mirror
with respect to more than one axis at a time.
Mode group
Axes and spindles that are technologically related can be combined into one mode group. Axes/spindles of a
BAG can be controlled by one or more → channels. The same → mode type is always assigned to the channels
of the mode group.
Mode of operation
An operating concept on a SINUMERIK control. The following modes are defined: → Jog, → MDA, →
Automatic.
