Glossary
Reference point
Machine tool position that the measuring system of the → machine axes references.
Rotary axis
Rotary axes apply a workpiece or tool rotation to a defined angular position.
Rotation
Component of a → frame that defines a rotation of the coordinate system around a particular
angle.
Rounding axis
Rounding axes rotate a workpiece or tool to an angular position corresponding to an
indexing grid. When a grid index is reached, the rounding axis is "in position".
Safety Functions
The control is equipped with permanently active montoring functions that detect faults in the
→ CNC, the → PLC, and the machine in a timely manner so that damage to the workpiece,
tool, or machine is largely prevented. In the event of a fault, the machining operation is
interrupted and the drives stopped. The cause of the malfunction is logged and output as an
alarm. At the same time, the PLC is notified that a CNC alarm has been triggered.
Scaling
Component of a → frame that implements axis-specific scale modifications.
Selecting
Series of statements to the NC that act in concert to produce a particular → workpiece.
Likewise, this term applies to execution of a particular machining operation on a given → raw
part.
Serial RS-232-C interface
For data input/output, the PCU 20 has one serial V.24 interface (RS232) while the
PCU 50/70 has two V.24 interfaces. Machining programs and manufacturer and user data
can be loaded and saved via these interfaces.
Setting data
Data, which communicates the properties of the machine tool to the NC, as defined by the
system software.
