W1: Tool offset
18.11 Sum offsets and setup offsets
Figure 18-51 MD18112 $MN_MM_KIND_OF_SUMCORR, bit 4 = 1 "setup offsets" + "sum offsets fine"
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
...
DL=1 ; Sum offset 1 is added to the previous D2 compensations, i.e.,
...
DL=2 ; Sum offset 2 is added to the D2 compensation instead of sum
...
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 significance 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 ]
R6 = $TC_SCP21[ 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).
; 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).
