<1> The tool moves to the position "machining profile top surface
height + clearance (Ct) in the tool axis direction" by rapid
traverse.
<2> The tool moves to the position "machining profile bottom surface
+ cutting allowance (Vt) in the tool axis direction + clearance
(Ct) in the tool axis direction" at the feedrate (Ftm) specified for
movement in the tool axis direction.
<3> The tool moves to the machining profile bottom surface at the
feedrate (Ft) specified for cutting in the tool axis direction.
<4> The tool approaches, in the tool radius direction, the in-feed
machining start point in the tool radius direction.
