2–AXES (X AND Z–AXIS) LATHES
TYPES OF MACHINING
PROGRAMS
259
CZ: Z coordinate of a cutting start point for finish
machining
NOTE
Pass point 2 and the cutting start point are automatically
determined in the same way as for rough machining.
JESCAPE AMNT EA: Movement along the X–axis (in outer/inner
surface machining: diameter) or along the
Z–axis (in end facing: radius) for retraction
after finish machining
NOTE
For finish bar machining, the finishing tool is moved along
the specified workpiece outline. At the end of machining,
the tool is retracted, cancelling tool nose radius com-
pensation.
For this clearance, the value obtained by multiplying the tool–tip radius
of the tool being used by 2 (or 4 when using a diameter value) is set when
a bar machining process is newly created.
Example of retraction in finish machining:
ESCAPE AMNT
X
Z
JS–DRCT RS: Direction of spindle rotation for finish
machining. Choose from [NORMAL] and
[REVERSE]
JSPINDL GEAR GM: Spindle gear. Choose from [AUTO], [LOW
GEAR], [MID GEAR 1], [MID GEAR 2], and
[HIGH GEAR].
JCOOLANT CM: Specifies whether to use coolant. Choose [ON]
or [OFF]. M8 (ON) or M9 (OFF) is output.
By setting bit 7 (OIL) of parameter No. 9763 to
1, a selection can be made from [TYPE 1],
[TYPE 2], and [OFF]. At this time, M8 (type
1), M7 (type 2), or M9 (OFF) is output.
JRESIDUAL CUT AU: Specifies automatic residual machining.
Specify whether to perform automatic residual
machining, in the same way as for rough
machining.
