Axial preset offset
The "Preset" function can be used to redefine the control zero in the machine coordinate system. The preset
values act on machine axes. Axes do not move when "Preset" is active.
10.4.3 Basic coordinate system (BCS)
Basic coordinate system (BCS)
The basic coordinate system (BCS) consists of three mutually perpendicular axes (geometry axes) as well as
other special axes, which are not interrelated geometrically.
Machine tools without kinematic transformation
BCS and MKS always coincide when the BCS can be mapped onto the MCS withouth kinematic transformation
(e.g., TRANSMIT /face transformation, 5-axis transformation and up to three machine axes).
On such machines, machine axes and geometry axes can have the same names.
Figure 10-14 MCS=BCS without kinematic transformation
Note
After Preset, the reference points are invalid!
If possible do not use this function.
