(a) Rapid traverse
•
Dry run OFF
The rapid traverse rate (#2001 rapid) is
applied.
Normal line control axis turning speed f
= Rapid traverse rate

Dry run OFF
Normal line control axis turning speed f

(Rapid traverse override)
(°/min)
For R=0, the following expression is
applied.
Normal line control axis turning speed f
= F
∗
(Rapid traverse override) (°/min)
F: Rapid traverse rate (#2001 rapid)
(mm/min)
R: Parameter (#8041 C-rot.R) (mm)
(Length from normal line control axis
center to tool nose)
(Note 1) If the normal line control axis
turning speed exceeds the rapid
traverse rate (#2001 rapid), the
speed is clamped to the rapid
traverse rate.
•
Dry run ON
The manual feedrate is applied.
Normal line control axis turning speed f
= Manual feedrate
∗
(Cutting feed
override) (°/min)
(Note 1) When the manual override valid is
ON, the cutting feed override is
valid.
(Note 2) If the normal line control axis
turning speed exceeds the cutting
feed clamp speed (#2002 clamp),
the speed is applied to the cutting
feed clamp speed.
(Note 3) When the rapid traverse is ON, the
dry run is invalid.

(Cutting feed override) (°/min)
F: Manual feedrate (mm/min)
R: Parameter (#8041 C-rot.R) (mm)
(Length from normal line control axis

(Note 1) When the manual override valid is
ON, the cutting feed override is
valid.
(Note 2) If the normal line control axis
turning speed exceeds the rapid
traverse rate (#2001 rapid), the
speed is applied to the rapid
traverse rate.
(Note 3) When the rapid traverse is ON, the
dry run is invalid.
