Detailed Description
2.5 Toolholder with orientation capability
Tool Compensation (W1)
2-84 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Machine kinematics:
$TC_CARR1 to $TC_CARR20 and $TC_CARR23
$TC_CARR18 to $TC_CARR20 define a further vector l
4,
, which is needed to describe the
machine with extended kinematics (both tool and workpiece can be rotated).
$TC_CARR21 and $TC_CARR22 contain the channel-axis identifiers of the rotary axes, the
positions of which can be used to determine the orientation of the toolholder with orientation
capability, if necessary.
Kinematic type:
$TC_CARR23 using letter T, P or M
The following three options are available for the kinematic type, for which both upper and
lower case text are permissible:
T: Only the Tool can be rotated (basic value).
P: Only the workpiece (Part) can be rotated.
M: Both tool and workpiece can be rotated (Mixed mode).
Any character other than the three mentioned here will result in the alarm 14153 if it is tried
to activate the toolholder with orientation capability.
Rotary axis parameters:
$TC_CARR24 to $TC_CARR33
The system variables in $TC_CARR24 to $TC_CARR33 can be used to define offsets, angle
compensations, Hirth tooth system, and axis limits.
Note
The system variables are available with and without active tool management.
Components and presetting of the chain/data block
The values $TC_CARR1 to $TC_CARR20 and $TC_CARR24 to $TC_CARR33 in the
toolholder data block are of NC language format type REAL.
The values $TC_CARR21 and $TC_CARR22 for the axis identifier of the first rotary axis (v
1
)
and the second rotary axis (v
2
) are of NC language format type AXIS. They are all preset to
zero.
The value $TC_CARR23 is initialized with the uppercase letter "T" (only tool can be rotated).
$TC_CARRn[m]
$TC_CARR[0]= 0 has a special meaning
