10.1 Brief description
10.1.1 Axes
Machine axes
Machine axes are the axes that actually exist on a machine tool.
Channel axes
Every geometry axis and every special axis is assigned to a channel and, therefore, a channel axis. Geometry
axes and additional axes are always traversed in "their" channel.
Geometry axes
The three geometry axes always make up a fictitious rectangular coordinate system, the basic coordinate system
(BCS).
By using FRAMES (offset, rotation, scaling, mirroring), it is possible to image geometry axes of the workpiece
coordinate system (WCS) on the BCS.
Special axes
In contrast to geometry axes, no geometrical relationship is defined between the special axes.
Path axes
Path axes are interpolated together (all the path axes of a channel have a common path interpolator).
All the path axes of one channel have the same acceleration phase, constant travel phase and delay phase.
Positioning axes
Positioning axes are interpolated separately (each positioning axis has its own axis interpolator). Each
positioning axis has its own feedrate and acceleration characteristic.
Synchronized axes
Synchronous axes are interpolated together with path axes (all path axes and synchronous axes of one channel
have a common path interpolator).
All path axes and all synchronous axes of a channel have the same acceleration phase, constant travel phase
and deceleration phase.
