X is diameter axis:

N90
N100
N110
N120

N140
N150
N160
N170
The compensation of the tool length is to be 1 mm in each axis (N80 to N100).
1 mm is thus added to the original length in lengths L2 and L3.
Twice the compensation value (2 mm) is added to the original tool length in L1, in order to
change the total length by 1 mm as required. If the positions approached in blocks N110 and
N130 are compared, it can be seen that each axis position has changed by 1 mm.
