6.9.2 Cylindrical Interpolation Cutting Point Compensation
Overview
The conventional cylindrical interpolation function controls the
movement of the tool center so that the tool axis moves along a
specified path on the cylindrical surface to always face toward the
rotation axis of the workpiece (cylindrical axis).
On the other hand, the cylindrical interpolation cutting point control
function controls the tool so that the tangent from the tool to the
cutting face of a contour figure passes the rotation center of the
workpiece at all times.
That is, the cutting face of a contour figure is always perpendicular to
the cylinder. Therefore, the figure of the cutting face can be kept
identical regardless of the cutter compensation.

ROTx, ROSx Setting linear or rotation axis.
ROSx ROTx Meaning
0 0
Linear axis
(1) Inch/metric conversion is done.
(2) All coordinate values are linear axis type. (Is not rounded in 0 to 360
°)
(3) Stored pitch error compensation is linear axis type (Refer to parameter No.3624)
0 1
Rotation axis (A type)
(1) Inch/metric conversion is not done.
(2) Machine coordinate values are rounded in 0 to 360
°. Absolute coordinate values are rounded or not
rounded by parameter No.1008#0(ROAx) and #2(RRLx).
(3) Stored pitch error compensation is the rotation type. (Refer to parameter No.3624)
(4) Automatic reference position return (G28, G30) is done in the reference position return direction and the
move amount does not exceed one rotation.
1 1
Rotation axis (B type)
(1) Inch/metric conversion, absolute coordinate values and relative coordinate values are not done.
(2) Machine coordinate values, absolute coordinate values and relative coordinate values are linear axis
type. (Is not rounded in 0 to 360
°).
(3) Stored pitch error compensation is linear axis type (Refer to parameter No.3624)
(4) Cannot be used with the rotation axis roll over function and the index table indexing function (M series)
Except for the above. Setting is invalid (unused)
