Frame types

Frame
A frame is a data structure that contains values for offset (TRANS), fine offset (FINE), rotation (ROT), mirroring
(MIRROR) and scaling (SCALE) for axes.
Axial frame
An axial frame contains the frame values of an axis.
Example of the data structure of an axial frame:
Axis TRANS
X 10.0
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
Axis TRANS
X 10.0
Y 0.0
Z 0.0
A 2.0
AX1 0.0
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
