Subblock
Block preceded by "N" containing information for a sequence, e.g. positional data.
Subroutine
Sequence of statements of a → part program that can be called repeatedly with different
defining parameters. The subroutine is called from a main program. Every subroutine can be
protected against unauthorized read-out and display. → Cycles are a form of subroutines.
Synchronization
Instructions in → part programs for coordination of sequences at certain machining points.
System variables
A variable that exists without any input from the programmer of a → part program. It is
defined by a data type and the variable name preceded by the character $. See → User-
defined variable.
Tapping without compensation chuck
This function allows threads to be tapped without a compensation chuck. By using the
interpolating method of the spindle as a rotary axis and the drilling axis, threads can be cut to
a precise final drilling depth e.g. for blind hole threads (requirement: spindles in axis
operation).
Text editor
The control system provides a function for editing Chinese characters in the program editor
and in the PLC alarm text editor.
This function is only available in the Chinese language version.
Tool
Active part on the machine tool that implements machining (e.g. turning tool, milling tool, drill,
etc.).
Tool nose radius compensation
Contour programming assumes that the tool is pointed. Because this is not actually the case
in practice, the curvature radius of the tool used must be communicated to the control which
then takes it into account. The curvature center is maintained equidistantly around the
contour, offset by the curvature radius.
Tool offset
Consideration of the tool dimensions in calculating the path.
