Basic coordinate system B-CS
The basic coordinate system is a 3-D Cartesian coordinate system.
Its coordinate origin is the end of the kinematics model.
The orientation of the basic coordinate system in most cases
corresponds to that of the machine coordinate system. There may
be exceptions to this if a machine manufacturer uses additional
kinematic transformations.
The kinematic model and thus the position of the coordinate
origin for the basic coordinate system is defined by the machine
manufacturer in the machine configuration. The user cannot modify
the machine configuration values.
The basic coordinate system serves to determine the position and
orientation of the workpiece coordinate system.
Soft key Application
The user determines the position and orientation
of the workpiece coordinate system by using a 3-
D touch probe for example. The control saves the
values determined with respect to the basic coordi-
nate system as BASE TRANSFORM. values in the
preset management.
The machine tool builder configures the
BASE TRANSFORM. columns of the preset management
in accordance with the machine.
