Linear transformation
The tool length can be uniquely defined in the MCS only if the MCS is generated by linear
transformation from the BCS.
This would be the case when:
•
no kinematic transformation is active
•
or orientation transformations (3-axis, 4-axis and 5-axis transformations) are active.
TOWWCS
Wear values in WCS (workpiece coordinate system):
•
If a toolholder with orientation capability is active, the tool vector is calculated as for
TOWMCS
, without taking the wear into account.
•
The wear data are interpreted in the workpiece coordinate system.
The wear vector in the workpiece coordinate system is converted to the machine coordinate
system and added to the tool vector.
TOWBCS
Wear values in BCS (basic coordinate system):
•
If a toolholder with orientation capability is active, the tool vector is calculated as for
TOWMCS
, without taking the wear into account.
•
The wear data are interpreted in the workpiece coordinate system.
The wear vector in the basic coordinate system is converted to the workpiece coordinate
system and added to the tool vector.
Nonlinear transformation
If a nonlinear transformation is active, e.g., with
TRANSMIT
, and the MCS is specified as the
desired coordinate system, the BCS is automatically used instead of the MCS.
Toolholder with orientation capability
A table component of the toolholder with orientation capability, if available, is not applied
directly to the coordinate systems, unlike a table (or part) component of the kinematic
transformation. A rotation described by such a component is represented in a basic frame or
system frame and is thus included in the transition from WCS to BCS.
Kinematic transformation
The table (or part) component of the kinematic transformation is described by the transition
from BCS to MCS.
