Important terms are listed below in alphabetical order, accompanied
by explanations. Cross-references to other entries in this glossary are
indicated by the symbol ->.
A destination for an axis movement is defined by a measure referring
to the origin of the currently active coordinate system.
See also -> incremental dimension.
All -> messages and alarms are displayed on the control panel in
plain-text form and accompanied by date and time and the symbol for
the appropriate deletion criterion.
Exporting files and/or directories to an external storage device.
Auxiliary functions can be used to pass -> parameters to the -> PLC in
the -> parts program, triggering reactions there which are defined by
the machine manufacturer.
The CNC axes are categorized by their functional scope as follows:
• Axes: interpolative path axes
• Auxiliary axes: non-interpolative infeed and positioning axes with
axis-specific feedrates. Auxiliary axes do not participate in
workpiece machining as such and include tool feeders, tool
magazines, etc.
In compliance with DIN 66217, axes are identified as X, Y, Z for a
right-handed rectangular Cartesian -> coordinate system rotating in
the clockwise direction. Rotary axes rotating around X, Y, Z are
assigned the identifiers A, B, C. Additional axes, which are parallel to
those specified, can be identified with other letters.
The unmachined workpiece.
Axis about which the tool spindle describes a controlled rotational and
positioning movement.
-> NC
Outline of a -> workpiece
See -> Machine coordinate system -> Workpiece coordinate system
(work).
Protected subroutine for execution of a recurring machining process
on the -> workpiece.
The editor allows programs/text/program blocks to be created,
modified, appended, moved in blocks and inserted.
Electronic handwheels are used to traverse the selected axes
simultaneously under manual control. The handwheel clicks are
analyzed by the increment analyzer.
