Signed angle relative to the Z-axis. The CW
direction viewed from the plus direction of the
rotation axis is positive. (-90≤R≤90).

3.SLANT FACE MACHINING (COORDINATE CONVERSION) CYCLE MACHINING TYPES B-63874EN/05
Direct origin specification (with the rotation center on the Z-axis): G1954
The machining plane rotates about the new point (reference point) that
is to become the workpiece origin of the XY plane.

V
REF. POINT Y
Y coordinate of a new workpiece origin
W
REF. POINT Z
Z coordinate of a new workpiece origin
R
SLANT ANGLE
Signed angle with respect to the X-axis. The CW
direction viewed from the plus rotation axis
direction is positive (-90 ≤ R ≤ 90).

B-63874EN/05
CYCLE MACHINING TYPES 3.SLANT FACE MACHINING (COORDINATE CONVERSION)
Indirect origin specification (with the rotation center on the Z-axis): G1955
The machining plane rotates about a specified reference point. Define
the workpiece origin of the XY plane, which is a new machining plane,
by specifying the distance (positive/negative value) from the reference
point.
COORD CONVERSION
Data item
Meaning
U
REF. POINT X
X coordinate of a reference point (workpiece
coordinate system before rotation)
W
REF. POINT Y
Y coordinate of a reference point (workpiece
coordinate system before rotation)
I
NEW WORK ORIGIN X’
X coordinate of the workpiece origin of the slant
J
NEW WORK ORIGIN Y’
Y coordinate of the workpiece origin of the slant
K
NEW WORK ORIGIN Z’
Z coordinate of the workpiece origin of the slant
R
SLANT ANGLE
Signed angle with respect to the Z-axis. The CW
direction viewed from the plus rotation axis
direction is positive (-90 ≤ R ≤ 90).

3.SLANT FACE MACHINING (COORDINATE CONVERSION) CYCLE MACHINING TYPES B-63874EN/05
Coordinate conversion cancel: G1959
After coordinate conversion is canceled, the tool moves to the entered
end point by rapid traverse. If no end point is specified, the tool will
not move.
CANCEL
Data item
Meaning
X*
END POINT X
X coordinate to which the tool is to move by rapid
traverse after coordinate conversion is canceled. If
this data is omitted, the tool will not move.
Y*
END POINT Y
Y coordinate to which the tool is to move by rapid
traverse after coordinate conversion is canceled. If
this data is omitted, the tool will not move.
Z*
END POINT Z
Z coordinate to which the tool is to move by rapid
traverse after coordinate conversion is canceled. If
this data is omitted, the tool will not move.
