Frame types

A frame is a data structure that contains values for offset (TRANS), fine offset (FINE), rotation
(ROT), mirroring (MIRROR) and scaling (SCALE) for axes.
When activating the frame, using the frame values, a static coordinate transformation for the
axes contained in the frame is performed using a defined algorithm.
Axial frame
An axial frame contains the frame values of an axis.
Example of the data structure of an axial frame for axis X:
Axis
X
Channel-specific frame
A channel-specific frame contains frame values for all channel axes (geometry, special and
machine axes).
Rotations (ROT) are only included in the calculation for geometry axes.
A channel-specific frame is only active in the channel in which the frame is defined.
Example of the data structure of a channel-specific frame:
● Geometry axes: X, Y, Z
● Special axes: A
● Machine axes: AX1

Global frame
A global frame contains the frame values for all machine axes.
A global frame is active in all channels of the NC.
Example of the data structure of a channel-specific frame:
● Machine axes: AX1, ... AX5
