• Tool path
<1> The tool moves to the position "cut-in start point + clearance (L,
M)" by rapid traverse.
<2> After moving to the center of the groove (in the Z-axis direction)
by rapid traverse, the tool cuts in in the X-axis direction at the
feedrate
(F) specified for the cutting direction. If pecking is
specified, the tool cuts a specified pecking amount while
retracting in the -X-axis direction between pecking cycles.
<3> When the tool reaches the groove bottom (but the finishing
allowance) in the X-axis direction, the tool retracts in the -X-axis
direction, shifts by a cut-in amount through the width in the
-Z-axis direction, and then cuts in the X-axis direction.
<4> After step <3> is repeated until one groove wall is reached, the
tool cuts another wall.
<5> After all portions are cut, the tool moves to the position "cut-in
start point
+ clearance (M)" in the Z-axis direction by rapid
traverse and is pulled out from the workpiece.

faces of a groove evenly in finishing.
[CORNER] : Cuts one side face and the entire
bottom successively then cuts the
other side face only in finishing.

V
ESCAPE AMOUNT
Distance by which the tool retracts from a cutting
surface when finishing is completed (radius value,
positive value)
Remark1) This item is displayed only when
[CORNER] is selected as a cutting end
position. The default value is 0.
Remark2) By referring to the parameter No. 27177
(minimum clamp value), the system sets
the data as an initial value.

• Tool path
Cutting end position [CENTER]
Cutting end position [CORNER]
<1> The tool moves to the position "cut-in start position + clearance
(L, M)" by rapid traverse.
<2> If [CENTER] is specified as the cutting end position, the tool
cuts in one of the groove walls and continues cutting to the center
(in the X-axis direction) of the groove at the finishing feedrate.
After retracting in the Z-axis direction, the tool performs the
same cutting operation for the other groove wall.
<3> If [CORNER] is specified as the cutting end point, the tool cuts
in to the bottom from the wall in the +X-axis direction, and
retracts by a return clearance in the X- and Z-axis directions and
then in the Z-axis direction. After this, the tool starts cutting from
the other groove wall and continues cutting to the edge of the
bottom, and then retracts by a return clearance in the X- and
Z-axis directions.
<4> The tool moves to the position "cut-in start point + clearance
(M)" in the Z-axis direction by rapid traverse.
