Detailed Description
2.9 Sum offsets and setup offsets
Tool Compensation (W1)
2-134 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Tool T = t is active. With the data in the figure, the following is programmed:
D2 ; Cutting edge compensations, i.e., $TC_DP3 to $TC_DP11 + wear
($TC_DP12 to $TC_DP20) + adapter dimension
...
DL=1 ; Sum offset 1 is added to the previous D2 compensations,
i.e., $TC_ECP13 + $TC_SCP13 to $TC_ECP21 + $TC_SCP21
...
DL=2 ; Sum offset 2 is added to the D2 compensation instead of sum
offset 1;
i.e., $TC_ECP23 + $TC_SCP23,...$TC_ECP31 + $TC_SCP31
...
DL=0 ; Deselection of sum offset.
Only the data of D2 remain active.
Reading/writing in the part program
The individual sets of sum offset parameters are differentiated according to the number
ranges of system variable $TC_SCP.
The meaning of the individual variables is similar to geometry variables $TC_DP3 to
$TC_DP11. Only length 1, length 2 and length 3 are enabled for the basic functionality
(variables $TC_SCP13 to $TC_SCP15 for the first sum offset of the cutting edge).
R5 = $TC_SCP13[ t, d ] ; Sets the value of the R parameter to the value
of the first component of sum offset 1 for
cutting edge (d)
on tool (t).
R6 = $TC_SCP21[ t, d ] ; Sets the value of the R parameter to the value
of the last component of sum offset 1 for
cutting edge (d) on tool (t).
R50 = $TC_SCP23[ t, d ] ; Sets the value of the R parameter to the value
of the first component of sum offset 2 for
cutting edge (d) on tool (t).
$TC_SCP43[ t, d ] = 1.234 ; Sets the value of the first component of sum
offset 4 for cutting edge (d) on tool (t) to the
value 1.234.
