e (set by a parameter)
Fig. 14.2.1 (e) Chamfering in Stock Removal in Turning (Type II)
The clearance e (specified in R) to be provided after cutting can also be
set in parameter No. 5133.
A sample cutting path is given below:

The offset of the tool tip radius is not added to finishing allowances
∆u and ∆w. In turning, the offset of the tool tip radius is assumed to be
W=0 must be specified ; otherwise, the tool tip may cut into one wall side.
For the first block of a repetitive portion, two axes X(U) and Z (W) must
be specified. When Z motion is not performed, W0 is also specified.
When only one axis is specified in the first block of a repetitive portion
When two axes are specified in the first block of a repetitive portion
When the first block does not include Z motion and type IIis to be used,
W0 must be specified.
