Mode groups
A mode group combines NC channels with axes and spindles to form a machining unit.
A mode group contains the channels that are required to run simultaneously in the same
mode from the point of view of the machining sequence.
Any axis can be programmed in any channel of a certain mode group. A mode group
therefore corresponds to an independent, multiple-channel NC.
Example
On large machine tools (machining centers), it may be necessary for a parts program to be
processed on one part of the machine while new workpieces to be machined need to be
clamped and set up on another part. Such tasks usually require two independent NC
controls.
With the mode group function, both tasks can be implemented on one NC control with two
mode groups because a different mode can be set for each mode group (AUTOMATIC mode
for the program processing, JOG for setting up a workpiece).
Mode group assignment
The configuration of a mode group defines the channels, geometry axes, machine axes and
spindles which it is to contain.
A mode group consists of one or several channels which must not be assigned to any other
mode group. Machine axes, geometry axes and special axes themselves are assigned to
these channels. A machine axis can only be assigned to the channels of one mode group
and can only traverse in this mode group.
A mode group is configured with the following data:
● Channel-specific machine data:
● Configuration data of the channels
