Synchronized axes take the same time to traverse their path as the
geometry axes take for their path.
1. Auxiliary function output
While a workpiece is being machined, technological functions (
auxiliary functions) can be output from the CNC program to the
PLC. These auxiliary functions are used for example to control
additional equipment for the machine tool, such as quills, grabbers,
clamping chucks etc.
2. High-speed auxiliary function output
For time-critical switching functions, the acknowledgement times
for the → auxiliary functions can be minimized and unnecessary
stops in the machining process can be avoided.
Instructions in → part programs for coordination of the operations in
different → channels at specific machining points.
A variable, which exists, although it has not been programmed by the
→ part program programmer. It is defined by a data type and the
variable name preceded by the character $.
See also → User-defined variable.
Teach-in is a means of creating or correcting part programs. The
individual program blocks can be input via the keyboard and executed
immediately. Positions approached via the direction keys or
handwheel can also be stored. Additional information such as G
functions, feedrates or
M functions can be entered in the same block.
A sequence of instructions to the NC control which combine to
produce a specific → workpiece. Likewise, performing a certain
machining operation on a specific → blank.
The part program management function can be organized according
to → workpieces. The size of the user memory determines the number
of programs and the amount of data that can be managed. Each file
(programs and data) can be given a name consisting of a maximum of
24 alphanumeric characters.

Programming in a Cartesian coordinate system, execution in a non-
Cartesian coordinate system (e.g., with machine axes as rotary axes).
