Press the [17 C–NOTC] soft key to select notching around the C–axis,
then specify the machining area, tool post, start point Z–coordinate, and
end point Z–coordinate.
Specifying these values automatically selects an end mill tool whose
length is greater than the machining depth (= end point Z–coordinate –
start point Z–coordinate) and determines the cutting conditions.
Also enter data for the cutting allowance X–coordinate and the finishing
allowance X–/Z–coordinate necessary for notching around the C–axis.
NOTE
The finishing allowance X–/Z–coordinate for nothing
around the C–axis must bespecified separately from the
finishing allowance entered as the initial cutting data
