Press the [18 C–CYL.] soft key to select cylindrical surface machining
around the C–axis, then specify the tool post, groove start point
X–coordinate, groove depth, and groove diameter.
Specifying these values automatically selects an end mill tool whose
length is greater than the groove depth and whose diameter is less than the
groove diameter, and determines the cutting conditions.
