CAUTION
1 Set the same tool tip radius (RN) for both tools. The system
does not check the data other than the radius of the tool tip.
It is recommended to use tools having an identical tip figure.
If tools having different tip figures are used, the workpiece
may vibrated during actual machining and the tool tip may
interfere with the workpiece.
2 A negative value cannot be specified as the delay (DA). The
operator is prompted to specify the delay only when outer
surface roughing is selected. The system accepts 0 or a
positive integer. If 0 is specified, type A is selected. If a
positive integer is specified, type B is selected.

Specify turret 1 (TL = 1) for the first tool and turret 2 (TL =
2) for the second tool.

(SD).
Unless the above instructions are observed, the system gives a warning
