CUT OFF POS. CO = (mm or inch). . . . . . . .
Specify the distance between the
cut off point and the inner surface
or center of the workpiece.
(The initial value is set in system
parameter 141.)
COND. RESET POS. CR = (mm or inch). . . .
Specify the distance between the
point at which the cutting
conditions are changed and the
cut off point. (The initial value is
set in system parameter 142.)
RETURN AMOUNT RA = (mm or inch). . . .
Specify the retraction distance
along the X–axis of the tool from
the point at which the cutting
conditions are changed.
(The initial value is set in system
parameter 143.)
CUTTING SPEED V1 = (m/min or feet/min). . . . . .
V2 = (m/min or feet/min)
FEED RATE F1 = (mm/rev or inch/rev). . . . . . . . . . .
F2 = (mm/rev or inch/rev)
For the example of cutting off shown in Fig. 3.4.9 (a), specify the
cutting speed and feedrate from a to b and b to c with V1 and F1,
respectively. Then specify the cutting speed and feedrate from c to d
with V2 and F2 respectively.
